the complete guide to fasting (review)

Considering the massive amount of research and interest in the idea of fasting, not a lot has been written for the general population on the topic.

Brad Pilon’s 2009 e-book Eat Stop Eat was a great, though fairly concise, resource on the mechanisms and benefits of fasting.

image08

Martin Berkhan’s LeanGains blog had a cult following for a while in the bodybuilding community.

image17Michael Mosley’s 2012 documentary Eat, Fast and Live Longer documentary piqued the public interest and was followed by the popular 5:2 Diet book.

Then in 2013, Jason Fung emerged onto the low carb scene with his epic six part Aetiology of Obesity YouTube Series in which he detailed a wide range of theories relating to obesity and diabetes.

Essentially, Jason’s key points are that:

  • simply treating Type 2 diabetes with more insulin to suppress blood glucose levels while continuing to eat the diet that caused the diabetes is futile,
  • people with Type 2 diabetes are already secreting plenty of insulin, and
  • insulin resistance is the real problem that needs to be addressed.

Jason’s Intensive Dietary Management blog has explored a lot of concepts that made their way into his March 2016 book, The Obesity Code.  However surprisingly, given that Jason is the fasting guy, the book didn’t talk much about fasting.

my experience with fasting

I have benefited personally from implementing an intermittent fasting routine after getting my head around Jason’s work.  I like the way I look and perform, both mentally and physically, after a few days of not eating.  I also like the way my belt feels looser and my clothes fit better.

Complete abstinence is easier than perfect moderation.

St Augustine

I recently did a seven day fast and since then I’ve done a series of four day fasts, testing my glucose and blood and breath ketones with a range of different supplements (e.g. alkaline mineral mix, exogenous ketones, bulletproof coffee / fat fast and Nicotinamide Riboside) to see if they made any difference to how I feel and perform, both mentally and physically.

Fasting does become easier with practice as your body gets used to accessing fat for fuel.

I love the mental clarity!   My workout performance and capacity even seems to be better when I’ve fasted for a few days.

My key fasting takeaways are:

  1. Fasting is not that hard. Give it a try.
  2. You can build up slowly.
  3. If you don’t feel good. Eat!

The more I learn about health and nutrition, the more I realise how critical it is to be able to burn fat and conserve glucose for occasional use.  We get into all sorts of trouble when we get stuck burning glucose.

Our body is like a hybrid car with a slow burning fat motor (with a big fuel tank) and high octane glucose motor (with a small fuel tank).  If you’re always filling the small high octane fuel tank to overflowing, you’ll always be stuck burning glucose and your fat burning engine will start to seize up (i.e. insulin resistance and diabetes).

image25

Reducing the processed carbs in our diet enables us to lower our insulin levels and retrain our body to burn fat again.  But nothing lowers insulin as aggressively and effectively as not eating.

Even though lots of Jason’s thoughts on fasting seem self-evident, his blog elucidating them has been very popular, perhaps because the concept of fasting is novel in the context of our current nutritional education.

We’ve been trained, or at least given permission, to eat as often as we want by the people that are selling food or sponsored by them.[1]

context

Jason’s angle on obesity and diabetes comes from his background as a nephrologist (kidney specialist) who deals with chronically ill people who are a long way down the wrong track before they come to his office.  Jason also talks about how he had tried to educate his patients about reducing their carbs, however after eating the same thing for 70 years this is just too hard for many people to change.

2016-10-29-6

Desperate times call for desperate measures!

image11

Many of these patients come to him jamming in hundreds of units a day of insulin to suppress blood glucose levels, even though their own pancreas is still likely secreting more than enough insulin.

image07

Rather than continuing to hammer more insulin to suppress the symptom (high blood glucose), the solution, according to Jason, is to attack the ultimate cause (insulin resistance) directly.

Jimmy Moore is well known to most people that have an interest in low carb or ketogenic diets.  Whether you agree with his approach, it’s safe to say that low carb and keto would not be as popular today without his role.

image06

Meanwhile Jason talks about trying to educate people about reducing the processed carbs from their diet not working, not because of the science but more due to people not being able to change their eating habits after 70 years.

the Complete Guide to Fasting

You’ve probably heard by now that Jason has teamed up with Jimmy to write The Complete  Guide to Fasting which captures Jason’s extensive thoughts on fasting from the blog along with Jimmy’s n=1 experiences and wraps them up in a cohesive comprehensive manual with a colourful bow.

image01

Jason and Jimmy both sent me a copy of their new 304 page book, The Complete Guide to Fasting, to review (thanks guys).   So here goes…

Similar to The Obesity Code, TCGTF is a compilation of ideas that Jason has developed on his Intensive Dietary Management blog.  Blogging is a great way to get the ideas together and thrash them out in a public forum.   Some people love to read the latest blog posts and debate the minutiae, however most people would rather spend the $9 and sit down with a comprehensive book and get the full story.

Unlike The Obesity Code, TCGTF is a bright, full colour production with great graphics that will make it worth buying the hard copy to have and to hold.

TCGTF did originally have the working title Fasting Clarity as a follow on from Jimmy’s previous Cholesterol Clarity and Keto Clarity.   However, other than Jimmy’s discussion of his n=1 fasting experiences, TCGTF is predominantly written in Jason’s voice building from his blog, so it wouldn’t be appropriate for it to have become the third in Jimmy’s Clarity series.

What is similar to Jimmy’s clarity series is that it’s easy to read and accessible for people who are looking for an entry level resource.  This book will be great for people who are interested in the idea of fasting.  It is indeed the complete guide to fasting and is full of references to studies, however it doesn’t go into so much depth as to lose the average reader with scientific detail and jargon.

The book covers:

  • Jimmy’s n=1 experience with fasting,
  • Dr George Cahill’s seminal work on the effects of fasting on metabolism, glucose, ghrelin, insulin, and electrolytes,
  • the history of fasting over the centuries,
  • myth busting about fasting,
  • fasting in weight loss,
  • fasting and diabetes, physical health, and mental clarity,
  • managing hunger during a fast,
  • when not to fast, and
  • when fasting can go wrong.

The book is complete with a section on fasting fluids (water, coffee, tea, broth) and a range of different protocols that you can use depending on what suits you.  What did seem out of place are the recipes for proper meals.  Apparently, the publisher insisted they include these to widen the appeal (If you don’t like the fasting bit you’ve still got some new recipes?)

Overall, the book will be an obvious addition to the library (or Kindle) of people who are already fans of Jason and / or Jimmy and want a polished, consolidated presentation of all their previous work with a bunch of new material added.

TCGTF will also be a great read for someone who is interested learning more about fasting and wants to start at the beginning.   TCGTF is the most comprehensive book on the topic of fasting that I’m aware of.

my additional 2c…

Jason doesn’t mind weighing into a controversial argument, using some hyperbole or dropping the occasional F-bomb for effect and Jimmy’s no stranger to controversy either, so I thought I’d take this opportunity to give you my 2c on some of the topical issues at the fringe that aren’t specifically unpacked in the book.  We learn more as we thrash out the controversial issues at the fringes.   Many arguments come down to context.

target glucose levels

Jason has come under attack for using the word ‘cured’ in relation to HbAc1 values that most diabetes associations would consider non-diabetic,[2] though are not yet optimal.[3]

In the book Jason does discuss relaxing target blood glucose levels during fasting.  This makes sense for someone taking a slew of diabetic medications.   They’re probably not going to continue the journey if they end up in a hypoglycaemic coma on day one.

image12

The chart below shows the real life blood glucose variability for someone with Type 1 Diabetes on a standard diet.  With such massive fluctuations in glucose levels, it’s impossible to target ideal blood glucose levels (e.g. Dr Bernstein’s magic target blood glucose number of 4.6 mmol/L or 83 mg/dL).

image31

If your glucose levels are swinging wildly due to a poor diet coupled with lots of medication, your glucose levels are simply going to tank when you stop eating.  Hence, a safe approach is to back off the medication, at least initially, until your glucose levels have normalized.

Being married to someone with Type 1 Diabetes, I have learned the practical realities of getting blood glucose levels as low as possible while still avoiding dangerous lows.[4]  My wife Monica doesn’t feel well when her blood glucose levels are too low, but neither does she feel good with high blood glucose levels.  Balancing insulin and food to get blood glucose levels as low as possible without experiencing lows requires constant monitoring.

The chart below shows how scattered blood glucose levels can be even if you’re fairly well controlled.   Ideally you want the average blood glucose level to be as low as possible while minimising the number of hypoglycaemic episodes (i.e. below the red line).  If you can’t reduce the variability you just can’t bring the average blood glucose level down.  The last thing you want is to be eating to raise your blood glucose levels because you had too much blood glucose lowering medication.

image24

Pretty much everyone agrees that it’s dumb to be eating crap food and dosing with industrial levels of insulin to manage blood glucose levels.   High levels of exogenous insulin just drive the sugar that is not being used to be stored as fat in your belly, then your organs, and then in the more fragile places like your eyes and the brain.

Jason’s perspective is that people who are chronically insulin resistant and morbidly obese are likely producing more than enough insulin.  The last thing they need is exogenous insulin which will keep the fat locked up in their belly and vital organs.  Dropping insulin levels as low as possible using a low insulin load diet and fasting coupled with reducing medications will let the fat flow out.

image00

fasting to optimise blood glucose levels

In the long run, neither high insulin nor high glucose levels are optimal.

image10

Once you’ve broken the back of your insulin resistance with fasting, you can continue to drive your blood glucose levels down towards optimal levels.

One of the most popular articles on the Optimising Nutrition blog is how to use your glucose meter as a fuel gauge which details how you can time your fasting based on your blood glucose levels to ensure they continue to reduce.

image04

Your blood glucose levels can help calibrate your hunger and help you to understand if you really need to eat.  I think this is a great approach for people whose main issue is high blood glucose levels and who aren’t ready to launch into longer multi day fasts.

image26

In a similar way, a disciplined fasting routine can help optimise blood glucose levels in the long term.  The chart below shows a plot of Rebecca Latham’s blood glucose levels over three months where she used her fasting blood glucose numbers AND body weight to decide if she would eat on any given day.

image09

While there is some scatter in the blood glucose levels, you can see that regular fasting does help to reduce blood glucose levels over the long term.

Once you’ve lost your weight , broken the back of your insulin resistance and stopped eating crap food, you may find that you still need some exogenous insulin or other diabetic medication to optimise blood glucose levels if you have burned out your pancreas.

fasting frequency

The TGTF book covers off on several fasting regimens such as intermittent fasting, 24 hours, 36 hours, 42 hours and 7 to 14 days.  One concept that I’m intrigued by, similar to the idea of using your glucose meter as a fuel gauge, is using your bathroom scale as a fuel gauge.

image02

The reality, at least in my experience, is that we can overcompensate for our fasting during our feasting and end up not moving forward toward our goal.

If your goal is to lose weight I like the idea of tracking your weight and not eating on days that your weight is above your goal weight for that day.

14633142_10209291396354349_7869008000126784615_o

Again, Rebecca Latham has done a great job building an online community around the concept of using weight as a signal to fast through her Facebook group  My Low Carb Road – Fasting Support.

image28

The chart below shows Rebecca’s weight loss journey through 2016 where she initially targeted a weight loss of 0.2 pounds AND a reduction of 0.25 mg/dL in blood glucose per day.   After three months, she stabilized for a period (during a period when she had a number of major family issues to look after).  She is now using a less aggressive weight loss goal as she heads for her long-term target weight at the end of the year.

image15

The chart below shows the fasting frequency required to achieve her goals during 2016.  Tracking her weight against her target rate of weight loss has required her to fast a little more than one day in three to stay on track.

image16

Eating quality food is part of the battle, but managing how often you eat is also an important consideration.  After you’ve fasted for a few days, you can easily excuse yourself for eating more when you feast again.  And maybe it’s OK to enjoy your food when you do eat rather than tracking every calorie and trying to consciously limit them.

The obvious caveat is that there are a lot of other things that influence your scale weight such as muscle gain, water, GI tract contents etc, but this is another way to keep yourself accountable over the long term.

FAST WELL, FEED WELL

Fasting is a key component of the metabolic healing process, but it’s only one part of the story.

image29

Fasting is like ripping out your kitchen to put in a new one.   You have to demolish and remove the old stovetop to put the new shiny one back in.  You don’t sticky tape the new marble bench top over the crappy old Laminex.  You have to clean out the old junk before you implement the new, latest, and greatest model.

image32

In fasting, the demolition process is called autophagy, where the body ‘self eats’ the old proteins and aging body parts.   The great thing about minimising all food intake is that you get a deeper cleanse than other options such as fat fast, 500 calories per day or a protein sparing modified fast (PSMF).

But keep in mind that it’s the feast after the fast that builds up the shiny, new body parts that will help you live a longer, healthier, and happier life.

“Fasting without proper refeeding is called anorexia.” 

Mike Julian

Even fasting guru Valter Longo is now talking about the importance of feast / fast cycles rather than chronic restriction.  In the end you need to find the right balance of feasting / fasting, insulin / glucagon, mTOR / AMPK that is right for you.

In TCGTF, Jason and Jimmy talk about prioritising nutrient dense, natural, unprocessed,  low carb, moderate protein foods after the fast.  I’d like to reiterate that principle and emphasise that nutrient density becomes even more important if you are fasting regularly or for longer periods.

In the long term, I think your body will drive you to seek out more food if you’re not giving it the nutrients it needs to thrive.  Conversely, I think if you are providing your body with the nutrients it needs with the minimum of calories I think you will have a better chance of accessing your own body fat and reaching your fat loss goals.

optimising insulin levels AND nutrient density

It’s been great to see the concept of the food insulin index and insulin load being used by so many people!  In theory, when people reduce the insulin load of their diet they more easily access their own body fat and thus normalizes appetite.

image30

Some people who are very insulin resistant do well, at least initially, on a very high fat diet.  However, as glycogen levels are depleted and blood glucose levels start to normalise, I think it is prudent to transition to the most nutrient dense foods possible while still maintaining good (though maybe not yet optimal) blood glucose levels.

The problem with doubling down on reducing insulin by fasting combined with eating only ultra-low insulinogenic foods is that you end up “refeeding” with refined fat after your fast.

image22

While lowering carbs and improving food quality is the first step, I think that, as soon as possible you should start focusing on building up your metabolic machinery (i.e.  muscles and mitochondria).   A low carb nutrient dense diet is part of the story, but I don’t see many people with amazing insulin sensitivity that don’t also have a good amount of lean muscle mass which is critical to ‘glucose disposal’, good blood sugar levels and metabolic health.

This recent IHMC video from Doug McGuff provides a stark reminder of why we should all be focusing on maximising strength and lean muscle mass to slow aging.

The chart below shows a comparison of the nutrient density of the various dietary approaches.  Unfortunately, a super high fat diet is not necessarily going to be as nutrient dense and thus support muscle growth, weight loss, or optimal mitochondrial function as well as other options.

image03

The chart below (click to enlarge) shows a comparison of the various essential nutrients provided by a high fat therapeutic ketogenic dietary approach versus a nutrient dense approach that would suit someone who is insulin sensitive.

image33

I developed a range of lists of optimal foods that will help people in different situations with different goals to maximise the nutrient density that should be delivered in the feast after the fast.   The table below contains links to separate blog posts and printable .pdfs.  The table is sorted from highest to lowest nutrient density.   In time, you may be able to progress to a more nutrient dense set of foods as your insulin resistance improves.

protein

Jason had  a “robust discussion” with Steve Phinney over the topic of ideal protein levels recently during the Q&A session at the recent Low Carb Vail Conference.

To give some context again, Phinney is used to dealing with athletes who require optimal performance and are looking to optimise strength.  Meanwhile Jason’s patient population is typically morbidly obese people who are on kidney dialysis and probably have some excess protein, as well as a lot of fat that they could donate to the cause of losing weight.

I also know that Jimmy is a fan of Ron Rosedale’s approach of minimising protein to minimise stimulation of mTOR.  Jimmy and Ron are currently working on another book (mTOR Clarity?).  Protein also stimulates mTOR which regulates growth which is great when you’re young but perhaps is not so great when you’ve grown more than enough.

The typical concern that people have with protein in a ketogenic context is that it raises blood insulin in people who are insulin resistant.  ‘Excess protein’ can be converted to blood glucose via gluconeogenesis in people who are insulin resistant and can’t metabolise fat very well.

Managing insulin dosing for someone with Type 1 Diabetes like my wife Monica is a real issue, though she doesn’t actively avoid protein.  She just needs to dose with adequate insulin for the protein being eaten to manage the glucose rise.

The chart below shows the difference in glucose and insulin response to protein in people who have Type 2 Diabetes (yellow lines) versus insulin sensitive (white lines) showing that someone who is insulin resistant will need more insulin to deal with the protein.

image14

As well as insulin resistance, these people are also “anabolic resistant” meaning that some of the protein that they eat is turned into glucose rather than muscle leaving them with muscles that are wasting away.

People who are insulin resistant are leaching protein into their bloodstream as glucose because they can’t mobilise their fat stores for fuel.  They are dependent on glucose and they’ll even catabolise their own muscle to get the glucose they need if they stop eating glucose.

While it’s nice to minimise insulin levels, I wonder whether people who are in this situation may actually need more protein to make up for the protein that is being lost by the conversion to glucose to enable them to maintain lean muscle mass.  Perhaps it’s actually the people who are insulin sensitive that can get away with lower levels of protein?

As well as improving diet quality which will reduce insulin and thus improve insulin resistance, in the long term it’s also very important to maintain and build muscle to be able to dispose of glucose efficiently and also improve insulin resistance.

In TCGTF Jason talks about the fact that the rate of the use of protein for fuel is reduced during a fast and someone becomes more insulin sensitive.  He goes to great lengths to point out that concern over muscle loss shouldn’t stop you trying out fasting (which is a valid point).

image18

A big part of the magic of fasting is that you clean out some of your oldest and dodgiest proteins in your body and set the stage for rebuilding back new high quality parts.   But the reality is that you will lose some protein from your body during a fast (though this is not altogether a bad thing).[5] [6]

Bodybuilders often talk about the “anabolic window” after a workout where they can maximise muscle growth after a workout.  Similarly, one of the awesome things about fasting is that you reduce your insulin resistance and anabolic resistance meaning that when at the end of your fast your body is primed to allocate the high quality nutrients you eat in the right place (i.e. your muscles not your belly or blood stream).

In the end, I think optimal protein intake has to be guided to some extent by appetite.  You’ll want more if you need it, and less if you don’t.

I think if we focus on eating from a shortlist of nutrient dense unprocessed foods we won’t have to worry too much about whether we should be eating 0.8 or 2.2 g/kg of lean body mass.

However, avoiding nutrient dense, protein-containing foods and instead “feasting” on processed fat when you break your fast will be counter-productive if your goal is weight loss and waste a golden opportunity to build new muscle.

are you really insulin resistant?

Insulin resistance and obesity is a continuum.

Not everyone who is obese is necessarily insulin resistant.

If you are really insulin resistant, then fasting, reducing carbs, and maybe increasing the fat content of your diet will enable you to improve your insulin resistance.  This will then help with appetite regulation because your ketones will kick in when your blood glucose levels drop.

However, if you continue to overdo your energy intake (e.g. by chasing high ketones with a super high fat, low protein diet), then chances are, just like your body is primed to store protein as muscle, you will be very effective at storing that dietary fat as body fat.

image05

I fear there are a lot of people who are obese but actually insulin sensitive who are pursuing a therapeutic ketogenic dietary approach in the belief that it will lead to weight loss.  If you’re not sure which approach is right for you and whether you are insulin resistant, this survey may help you identify your optimal dietary approach.

image19

optimal ketone levels

Measuring ketones is really fascinating but confusing as well.

“Don’t be a purple peetone chaser.”

Carrie Brown, The Ketovangelist Podcast Ep 78

Urine ketones strips have limited use and will disappear as you start to actually use the ketones for energy.

In a similar way blood ketones can be fleeting.  Some is better than none, but more is not necessarily better.  As shown in the chart of my seven day fast below I have had amazing ketones and felt really buzzed at that point but since then I haven’t been able to repeat this.  I think sometimes as your body adapts to burning fat for fuel the ketones may be really high but then as it becomes efficient it will stabilise and run at lower ketone levels even when fasting.

image27

If your ketone levels are high when fasting then that’s great.  Keep it up.  They might stay high.  They might decrease.  But don’t chase super high ketones in the fed state unless you are about to race the Tour de France or if you want your body to pump out some extra insulin to bring them back down and store them as fat.

image20

The chart below shows the sum of 1200 data points of ketones and blood glucose levels from about 30 people living a ketogenic lifestyle.  Some of the time they have really high blood ketone levels but I think the real magic of fasting happens when the energy in our bloodstream decreases and we force our body to rely on our own body fat stores.

the root cause of insulin resistance is…

So we’ve worked out that large amounts of processed carbs drive high blood glucose and insulin levels which is bad.

We’ve also worked out that insulin resistance drives insulin levels higher, which is bad.

But what is the root cause of insulin resistance?

I think Jason has touched on a key component in that, as with many things, resistance is caused by excess.  If we can normalise insulin levels, then our sensitivity to insulin will return, similar to our exposure to caffeine or alcohol.

However, at the same time, I think insulin resistance is potentially more fundamentally caused by our sluggish mitochondria that don’t have enough capacity (number or strength) to process the energy we are throwing at them, regardless of whether they come from protein, carbs, or fat.

image13

A low carb diet lowers the bar to enable us to normalise our blood glucose levels.  However, the other end of the spectrum is focusing on training our body and our mitochondria to be able to jump higher.  In the long term this is achieved through, among other things, maximising nutrient dense foods and building lean body mass through resistance exercise.

image23

summary

  1. The Complete Guide to Fasting is, as per the title, the complete guide to fasting. It’s the most comprehensive guide to the nuances of fasting out there and there’s a good balance between the technical detail, while still being accessible for the general public.
  2. Fasting can help optimise blood glucose and weight in the long term, with a disciplined regimen.
  3. Fasting makes the body more insulin sensitive and primes it for growth. When you feast after you fast, it is ideal to make sure you maximise nutrient density of the food you eat as much as possible while maintaining reasonable blood glucose levels.
  4. Understanding your current degree of insulin resistance can help you decide which nutritional approach is right for you. As you implement a fasting routine and transition from insulin resistance to insulin sensitivity you will likely benefit from transitioning from a low insulin load approach to a more nutrient dense approach.

how to make endogenous ketones at home

I’ve spent some time lately analysing these 1100 ketone vs glucose data points looking for the secret to achieving optimal ketone values for weight loss and health.

image23

As you can see from this chart, there is a relationship between ketones and glucose.  As your blood glucose levels decrease your blood ketones rise to compensate.

Different glucose : ketone relationships for different people

It seems that each person has a unique relationship between their blood glucose and ketone values that gives us an insight to understand their insulin resistance status and metabolic health.

image02

Characterisation of different metabolic states

Similar to Dr Kraft’s insulin curves, we can characterise different levels of insulin resistance metabolic health using the relationship between glucose and ketones.

image27

If you want to know why hyperinsulinemia is the “unifying theory of chronic disease” it’s worth taking the time to read up on it to provide some more context for the discussion later in this article. [1] [2] [3] [4] [5]

Type 2 Diabetes

If you have type 2 diabetes and your blood glucose levels are consistently high, you are not metabolising carbohydrates well, and will likely benefit from a lower insulin load dietary approach.

When you go a long time between meals, your ketones don’t kick in because of high insulin levels and / or your mitochondria are not functioning optimally.  You feel tired and hangry.

Particularly in the early stages when someone is still insulin resistant, a lower insulin load dietary approach will help with satiety and carb cravings while keeping blood glucose levels under control.

Hyperinsulinemia and metabolic disorders

If your blood glucose levels are very low and ketone levels are also very low, you may have an infection or a metabolic disorder that is stopping you from producing enough energy.

The yellow line in the chart above is based on an actual person who is suffering from a range of metabolic related issues including obesity, PCOS, depression, etc.  For these people, EXOGENOUS ketones may help to relieve the debilitating symptoms of acute Hyperinsulinemia.

Exciting research is currently underway looking at the use of EXOGENOUS ketones as an adjunct treatment for cancer or to provide energy directly to the mitochondria for people with epilepsy, dementia, Alzheimer’s and the like.[6]  [7]  

2016-08-11.png

Patrick Arnold, who worked with Dr Dominic D’Agostino to develop the first ketone esters and BHB salts, has noted that exogenous ketones may help alleviate the symptoms of the ‘keto flu’ during the transition from a high carb to a low carb dietary approach.


However, as noted by Robb Wolf, once you have successfully transitioned to a lower carb eating style you would need to reduce or eliminate the exogenous ketones to enable your body to fully up-regulate lipolysis (fat burning), maximise ENDOGENOUS ketone production and access your ENDOGENOUS FAT stores.

2016-08-08.png

Insulin resistant

Someone with diabetes who persists with a nutrient dense low insulin load dietary approach may be able to successfully normalise their blood glucose and insulin levels.  When this happens your body will be able to more easily release ENDOGENOUS ketones which will help improve satiety between meals, and decrease appetite which will in turn lead to weight loss.  Exercising to train your body to do more with less is also helpful.

image20

If you are insulin resistant you are probably not able to metabolise carbohydrates, protein or fats very well.  The light blue “mild insulin resistance” line is based on my ketone and glucose values when I started trying to wrap my head around this ketosis thing.

image27

I enthusiastically started adding unrestricted amounts of fat from all the yummy stuff (cheese, butter, cream, peanut butter, BPC etc) in the hope of achieving higher ketone levels and therefore weight loss, but I just got fatter and more inflamed as you can see in the photo on the left.  My blood tests suggested I was developing fatty liver in my mid 30s!  And I thought I was doing it right with the bacon and BPC?!?!?

The photo on the right is after I worked out how to decrease the insulin load of my diet and learning about intermittent fasting from Jason Fung.  I realised that ENDOGENOUS ketosis and weight loss is caused by a lower dietary insulin load, not more EXOGENOUS fat on your plate or in your coffee cup.

image05

I recently had my HbA1c tested at 4.9%.  It’s getting there.  But knowing what I know now about the importance of glucose control,  I would love to lose a bit more weight and see my HbA1c even lower.

I recently purchased a couple of bottles of KetoCaNa from the USA after hearing a number of podcast interviews with Dominic D’Agostino and Patrick Arnold.[8] [9]

This metabolic jet fuel is definitely fascinating stuff!  My experience is that it gives me the buzz like a BPC, but also has an acute diuretic effect (meaning I need to stay close to a toilet and long drives to work in slow traffic were sometimes humiliating).

I had hoped it would have a weight loss effect like some people seemed to be saying it would.

2016-08-10

I did find it had an amazing impact on my appetite.  While it was in my system I didn’t care as much about food.  However once the ketones were used up my appetite came flooding back.  It was like I had ‘bonked’ all of a sudden and needed LOTS OF FOOD NOW!

image17

Unfortunately my hunger and subsequent binge eating seemed to offset the short term appetite suppression.  And it was not going to be financially viable for me to maintain a constant level of artificially elevated ketone levels.

I asked around to see if anyone had come across studies demonstrating long term weight loss effects of exogenous ketones.[11]   It was a VERY enlightening discussion if you want to check it out here.  Wow!

image30

The Pruvit FAQ says that one of the benefits of Keto//OS is weight loss, however no reference to the research studies was provided to Pruve this claim.

AVPageView 11082016 13036 PM.bmp.jpg

Also, the studies that were referenced in the Pruvit FAQ all appear to relate to the benefits of ENDOGENOUS or nutritional ketosis rather than EXOGENOUS ketone supplementation.

According to a Pruvit tele-seminar the EXOGENOUS ketone salts were not designed to be a weight loss product and hence have not been studied for weight loss.

The only studies that we could find that mentioned EXOGENOUS ketone supplementation and weight loss were on rats an they found that there was no long term effect on weight loss.[12]   

So in spite of my hopeful $250 outlay it seems that exogenous ketones ARE just a fuel source after all.

image06

Even the experts don’t seem to think exogenous ketones help with fat loss.

Confused yet?  I don’t blame you.

Metabolically healthy

The “metabolically healthy” line in the chart above is based on RD Dike man’s ketone and glucose data when he recently did a 21 day fast.

image32

Due to his hard earned metabolic health and improved insulin resistance he has developed the ability to fairly easily release ketones when goes longer periods between meals.

2016-08-10 (2).png

RD has achieved a spectacular HbA1c of 4.4%.  Perhaps a two or three day water only fast testing blood glucose and ketones with no exercise would be a useful test of your insulin status?  You could use RD’s line as the gold standard.

image04

In spite of his improvement in insulin resistance and blood glucose control, he still says the “siren” of hunger is incredibility difficult to resist and mastering appetite is more challenging than particle physics.  As a Chief Scientist at Lockheed Martin, he would know.

RD also told me that when he is not fasting and is eating his regular nutrient dense higher protein meals his ketone levels are not particularly high. While RD fairly easily produces ketones, it seems they are also quickly metabolised so they do not build up in his bloodstream.

I know Luis Villasenor of Ketogains finds the same thing.

image10

Total energy = ketones + glucose

Where this gets even more interesting is when we look at the glucose and ketone data in terms of TOTAL ENERGY.  That is, from both glucose and ketones.

2016-08-12 (11)

The average TOTAL ENERGY of the 1100 data points from these 26 fairly healthy people working hard to achieve nutritional ketosis is 6.1mmol/L. It seems the body works to maintain homeostasis around this level.

When the TOTAL ENERGY in our bloodstream increases outside of the normal range it appears the body raises insulin to store the excess energy.  That is, unless you have untreated Type 1 Diabetes, in which case you end up in diabetic ketoacidosis with high blood glucose and high ketones.

Regardless of whether your energy takes the form of glucose, ketones or free fatty acids they all contribute to acetyl-coA which is oxidized to produce energy.  Forcing excess unused energy to build up in the bloodstream is typically not desirable and can lead to long term issues (gyration, oxidized LDL etc).

I’m not sure if ketones can be converted to glucose or body fat, but it makes sense that excess glucose would be converted to body fat via de novo lip genesis to decrease the TOTAL ENERGY in the blood stream to normal levels.

A number of studies seem to support this view including Roger Unger’s 1964 paper the Hypoglycemic Action of Ketones.  Evidence for a Stimulatory Feedback of Ketones on the Pancreatic Beta Cells.[14]

Ketone bodies have effects on insulin and glucagon secretions that potentially contribute to the control of the rate of their own formation because of antilipolytic and lipolytic hormones, respectively.  Ketones also have a direct inhibitory effect on lipolysis in adipose tissue.[15]

This guy seems to agree too.  But what would he know? [16]  [17] [18]

image26

Looking at the glucose and ketones together in terms of TOTAL ENERGY was a bit of an ‘ah ha’ moment for me.  It helped me to understand why people like Seyfried and D’Agostino always talk about the therapeutic benefits and the insulin lowering effects of a calorie restricted ketogenic diet. [19] [20] [21] [22]

Dealing with high ketones and high glucose typically a concern fro the body because it just doesn’t happen in nature with real whole foods.  But now we have refined grains, HFCS, processed fats and exogenous ketones to ‘bio-hack’ our metabolism and send it into overdrive.

While fat doesn’t normally trigger an insulin response, it seems that excess unused energy in the blood stream, regardless of the source, will trigger an increase in insulin to reduce the TOTAL ENERGY in the blood stream.

I am concerned that if people continue to enthusiastically zealously focus on pursuing higher blood ketones “through whatever means you can”[24] in an  effort to amplify fat loss they will promote excess energy in the bloodstream which will lead to insulin resistance and hyperinsulinemia.

Using multi-level marketing tactics to distribute therapeutic supplements to the uneducated masses who are desperate to lose weight with a ‘more is better’ approach also troubles me deeply.

My heart sank when I saw this video.

MORE investigation required?

There are anecdotal reports that use of exogenous ketones provide mental clarity, enhanced focus and athletic performance benefits.  At the same time there are also people who have been taking these products for a while that don’t appear to be doing so well.

A July 2016 study Ketone Bodies and Exercise Performance: The Next Magic Bullet or Merely Hype? didn’t find that EXOGENOUS ketones were very exciting.

Recently, ketone body supplements (ketone salts and esters) have emerged and may be used to rapidly increase ketone body availability, without the need to first adapt to a ketogenic diet. However, the extent to which ketone bodies regulate skeletal muscle bioenergetics and substrate metabolism during prolonged endurance-type exercise of varying intensity and duration remains unknown. Therefore, at present there are no data available to suggest that ingestion of ketone bodies during exercise improves athletes’ performance under conditions where evidence-based nutritional strategies are applied appropriately.

Another study by Veech et al (who is trying to bring his own ketone ester to market) from August 2016 Nutritional Ketosis Alters Fuel Preference and Thereby Endurance Performance in Athletes found in favour of ketones.

Ketosis decreased muscle glycolysis and plasma lactate concentrations, while providing an alternative substrate for oxidative phosphorylation. Ketosis increased intramuscular triacylglycerol oxidation during exercise, even in the presence of normal muscle glycogen, co-ingested carbohydrate and elevated insulin. These findings may hold clues to greater human potential and a better understanding of fuel metabolism in health and disease.

I can understand how exogenous ketones could be beneficial for someone who is metabolically healthy and consuming a disciplined hypo-caloric nutrient dense diet.  They would likely be able to auto regulate their appetite to easily offset the energy from the EXOGENOUS ketones with less food intake.

While it seems that EXOGENOUS ketones assist in relieving the symptoms of metabolic disorders I’m yet to be convinced that a someone who is obese and / or has Type 2 Diabetes would do as well in the long term, especially if they were hammering MOAR fat and MORE exogenous ketones (along with maybe some sneaky processed carbs on the side) in an effort to get their blood ketones as higher in the hope of losing body fat.

Some questions that I couldn’t find addressed in the Pruvit FAQ that I think would be interesting to study in a long term controlled environment in the in the future are:

  1. What is the a safe dose limit of EXOGENOUS ketones for a young child?  How would you adjust their maximum intake based on age and weight?
  2. IF EXOGENOUS ketones do have a long term weight loss effect what is the upper limit  of intake of EXOGENOUS ketones to avoid stunting a child’s growth?
  3. Is there a difference in the way EXOGENOUS ketones are processed in someone is metabolically healthy versus someone who is very insulin resistant?
  4. Does the affect on appetite continue beyond the point that the ketones are out of your system?
  5. Do you need to take EXOGENOUS ketones continuously to maintain appetite suppression?  Does the effect of ENDOGENOUS wear off as your own ENDOGENOUS ketone production down regulates?  Do you need to keep taking more and more EXOGENOUS ketones to maintain healthy appetite control?
  6. How should someone with Type 2 Diabetes adjust their medication and insulin dose based on their dose of EXOGENOUS ketones?  Should they be under medical supervision during this period?
  7. Is there a difference in health outcome if you are taking EXOGENOUS ketones in the context of a hypo-caloric ketogenic diet versus a hyper-caloric ketogenic diet?  What about a diet high in processed carbs?
  8. Is there a minimum effective dose to achieve optimal long term benefits to your metabolic health or is MORE better?
  9. Are the long term health benefits of EXOGENOUS ketones equivalent to a calorie restricted ketogenic diet?

Unfortunately, I think we will find the answers to these questions sooner rather than later with the large scale experiment that now seems to be well underway.

Perhaps the burden of proof is actually on Pruvit to prove it rather getting their Pruvers to demonstrate that within 59 minutes they are successfully peeing out the product they’ve just paid some serious money for!

The lower the better?

Alessandro Ferretti recently made the observation that metabolically healthy people tend to have lower TOTAL ENERGY levels at rest (and hence have a lower HbA1c), but are able to quickly mobilise glycogen and fat easily when required (e.g. when fasting or a sprint). They are metabolically flexible[25] and metabolically efficient.[26]   

These people would have been able to both conserve energy during a famine and run away from a tiger and live to become our ancestors, while the ones who couldn’t didn’t.

image29

Similar to RD Dikeman, John Halloran is an interesting case.  Recently he has been putting a lot of effort into eating nutrient dense foods, intermittent fasting and high intensity exercise.

image13

He is also committed to improving his metabolic fitness to be more competitive in ice hockey.  His resting heart rate is now a spectacular 45 bpm!

image08

And he’s been able to lose 10kg (22lb) during July 2016!

image12

At 5.2mmol/L (i.e. glucose of 4.0mmol/L plus ketones of 1.2mmol/L) John’s TOTAL ENERGY is lower than the average of the 26 people shown in the glucose + ketone chart above.  Looking good John!

It seems excellent metabolic health is actually characterised by lower TOTAL ENERGY.

MORE is not necessarily BETTER when it comes to health.

Fast well, feed well

To clean up the data a little I removed the ketones vs glucose data points for a couple of people who I thought might be suffering from pancreatic beta cell burnout and one person that was taking exogenous ketones during their fast that had a higher TOTAL ENERGY.  I also removed the top 30% of points that I thought were likely high due to measuring after high fat meals.

So now the chart below represents the glucose and ketone values for a group of reasonably metabolically healthy people following a strict ketogenic dietary approach, excluding for the effect of high fat meals, BPC, fat bombs and the like.

image22

The average ketone value for this group of healthy people trying to live a ketogenic lifestyle is 0.7mmol/L. Their average glucose is 4.8mmol/L (or 87mg/dL). The average TOTAL ENERGY is 5.5mmol/L or 99mg/dL.

It seems we may not necessarily see really high ketone levels in our blood even if we follow a strict ketogenic diet, particularly if we are metabolically healthy and our body is using to ketones efficiently.

The real ketone magic

When we deplete glucose we train our body to produce ketones.

This is where autophagy, increased NAD+ and SIRT1 kicks in to trigger mitochondrial biogenesis and ENDOGENOUS ketone production (i.e. the free ones).[27]   The REAL magic of ketosis happens when all these things happen and ketones are release as a byproduct.  I do not believe that simply adding EXOGENOUS ketones will have nearly as much benefit to your mitochondria, metabolism and insulin resistance as training your body to produce ENDOGENOUS ketones in a low energy state.

image33

Everything improves when we train our bodies to do more with less (e.g. fasting, high intensity exercise, or even better fasted HIIT).  Resistance to insulin will improve as your insulin receptors are no longer drowning in insulin caused by high TOTAL ENERGY building up in your bloodstream.

image01

Driving up ketones artificially through EXOGENOUS inputs (treating the symptom) does NOT lead to increased metabolic health and mitochondrial biogenesis (cure) particularly if you are driving them higher than normal levels and not using them up with activity.

You may be able to artificially mimic the buzz that you would get when the body produces ketones ENDOGENOUSLY, however it seems you may just be driving insulin resistance and hyperinsulinemia if you follow a “MORE is better” approach.

Simply managing symptoms with patented products for profit without addressing the underlying cause often doesn’t end well.

Just like having low blood glucose is not necessarily good if it is primarily caused by high levels of EXOGENOUS insulin couple with a poor diet, or having lower cholesterol due to statins, having high blood ketone values is not necessarily a good thing if it is achieved it by driving up the TOTAL ENERGY in your blood stream with high levels of purified fat and EXOGENOUS ketones.

Nutrient density

When we feed our body with quality nutrients we maximise ATP production which will make us feel energised and satisfied.  Nutrient dense foods will nourish our mitochondria and reduce our drive to keep on seeking out nutrients from more food.  Greater metabolic efficiency will lead to higher satiety, which leads to less food intake, which leads to a lower TOTAL ENERGY, greater mitochondrial biogenesis, improved insulin sensitivity and lower blood glucose levels.

Prioritising nutrient dense real food is even more important in a ketogenic context.[28]  While we can always take supplements, separating nutrients from our energy source is never a great idea, whether it be soda, processed grains, sugar, glucose gels, HFCS, protein powders, processed oils or exogenous ketones.

Based on my analysis of nutrient density I don’t think you should be trying to avoid protein and carbohydrates in the pursuit of higher ketone levels unless you have a legitimate medical reason for perusing therapeutic ketosis (e.g. cancer, Alzheimer’s, epilepsy, dementia etc).

image09

I believe the best approach is to maximise nutrient density as much as possible while working within the limits of your metabolic health and your pancreas’ ability to maintain normal blood glucose levels.

image14

Intermittent fasting

If your goal is metabolic health, weight loss and improving your ability to produce ENDOGENOUS ketones, then developing a practice of FEASTING and FASTING is important.

To start out, experiment by extending your fasting periods until your TOTAL ENERGY is decreasing over time.  This will cause your circulating insulin levels to decrease which will force your body to produce ENDOGENOUS ketones from your ENDOGENOUS fat stores.

image03

Check out the how to use your glucose meter as a fuel gauge article or Jason Fung’s Intensive Dietary Management blog for some more ideas on how to get started with fasting.   Rebecca Skvorc Latham has also developed a fasting protocol using weight to guide your eating schedule if your primary goal is weight loss rather than blood glucose control.

image24

If you really want to measure something, see how low you can get your glucose levels before your next meal.  Then when you do eat, make sure you choose the most nutrient dense foods you possibly can to build your metabolic machinery and give your mitochondria the best chance of supporting a vibrant, active and happy life.

As my wise friend Raymund Edwards keeps reminding me, FAST WELL, FEED WELL.

 

 

Epilogue

Like most people dabbling in this low carb thing, I’m still on a journey.

I’d love to be able to share shirtless photos like Ted and Dom but I’m still working to overcome my own genetic propensity for diabetes, obesity, Alzheimer’s and Parkinson’s.  I’m still learning and working out how to apply these things in my own life.

Although I do sometimes check blood glucose levels before meals to see how I’m tracking I haven’t been testing ketones much for a year or so after I realised chasing high ketones with more dietary fat wasn’t helping me lose weight.

However after writing this article using other peoples’ data, I was intrigued to see how my ketones were travelling.

This was mid-morning after a kettlebell session.

I was able to get my heart rate up to 190 bpm which is my highest ever!  My daughter joined me today so there was some downtime between sets.  Usually I do an exercise until my heart rate gets up to at least 170 bpm.  I then stop and wait until it drops back down to 140 bpm and then go again.

My aim is to train my mitochondria to pump out more power with less energy (i.e. fasted) to improve insulin sensitivity as well as mitochondrial efficiency and drive  mitochondrial bio-genesis.

You can get a lot of work done in an intense 25 to 30-minute session with these weapons of torture that I keep downstairs in my garage (although I don’t think it really matters what you do as long as you push your body to do more with less).

My appetite today was great so I didn’t feel the need to eat until I had dinner with my family.

Previously I would have not been happy with these ketone readings and would have wanted to drive my ketones higher to get into the ‘optimal ketone zone’.  I would have wondered “Maybe I should have eaten some MORE butter or had a BPC to drive ketones higher to facilitate fat loss?”

But given I’d still like to lose some more body fat I’m pretty happy with these numbers.

  • My total energy is low (4.5mmol/L and 5.1mmol/L).  Check.
  • Ketones are present but not too high which means I’m able to mobilise fat but not building it up in my bloodstream.  Check.
  • Blood glucose is low.  Check.

All good!  Feeling crisp, happy and vibrant thanks to ENDOGENOUS ketones!

(Sorry.   I can’t sell you mine.  You’ll have to make your own.)

REVERSION Y REMISION DE LA DIABETES TIPO 2 CASO DE ANTONIO C. MARTINEZ II

¿Puede el ayuno intermitente optimizar los niveles de glucosa en la sangre y reducir la necesidad de medicamentos para la diabetes? Antonio Martínez estaba ansioso por descubrirlo, por lo que se propuso realizar un experimento con él mismo.

[for the English version of this post click here]

El Dr. Antonio C. Martinez II., es un Abogado reconocido de nivel distinguido por Martindale Hubbard, y de la Red Legal de los Mejores Abogados (Top Lawyers) en Nueva York y un hombre de negocios que trabajó para el ya fenecido Dr. Robert C. Atkins MD en relaciones gubernamentales y apareció en su programa de radio en los años 90. Fue uno de los principales cabilderos que logró la aprobación de la Ley de Educación y Salud de los Suplementos Dietéticos de 1994 (DSHEA). Ha participado activamente en cuestiones de salud en las leyes y políticas a lo largo de su carrera. En los años 90 Antonio adoptó un enfoque bajo en carbohidratos para bajar de peso durante un tiempo, pero luego retomó una dieta moderada en carbohidratos. No fue hasta que Antonio comenzó a tener sus propios problemas de salud, como la diabetes tipo 2 y un ataque cardíaco, que se dio cuenta que necesitaba intensificar sus esfuerzos para elevar la calidad de su nivel de vida con respecto a su salud.

image07

DIAGNOSTICO: DIABETES TIPO 2

Antonio tiene antecedentes familiares de diabetes tipo 2, ya que ambos padres sufren de la enfermedad, así que es diagnosticado con diabetes tipo 2 en 2002, por lo que los médicos le indicaron inicialmente empezar a tomar Metformina y a partir del 2008 utilizar Janumet. Con la ayuda de éstos Antonio mantenía un HbA1c (HbA1c se refiere a la hemoglobina glucosilada ( A1c ), que identifica la concentración promedio de glucosa en plasma)  en los 6s y fue elogiado por sus médicos por su gran control de la glucosa en sangre, sin embargo, a pesar de que los mantuvo por debajo de los recomendados por la Asociación Americana de Diabetes (un máximo de HbA1c del 7%) ,  Antonio en realidad estaba en el rango de alto riesgo para la enfermedad cardiovascular, como se muestra en la siguiente tabla. Durante este tiempo él siempre fue informado por sus médicos de que su A1c estaba entre 6 y 7 se encontraba dentro de las directrices médicas.

image05

Si bien los medicamentos antidiabéticos ayudan a disminuir los niveles de glucosa en la sangre (es decir, el de los síntomas) estos datos que se muestran a continuación muestran que los medicamentos no reducen necesariamente el riesgo de enfermedades o permiten que la grasa de sus órganos puedan ser lanzados para restaurar la sensibilidad a la insulina (es decir, la solución).

image09

Como se muestra en la tabla a continuación, la insulina es una hormona anabólica que permite que el cuerpo construya reservas de energía en el cuerpo. Sin embargo, si su problema es la hiperinsulina, la diabetes tipo 2 o hígado graso, entonces su objetivo debe ser reducir el nivel de glucosa en la sangre y los niveles de insulina para permitir que la grasa almacenada se metabolice a energía. Parece que simplemente tomando medicamentos para reducir el alto nivel de glucosa en la sangre sin cambios en la dieta va a conducir la energía de nuevo en el almacenamiento en forma de grasa, incluso dentro el corazón, el hígado y el páncreas.

El siguiente diagrama del Dr. Ted Naiman ayuda a explicar cómo la resistencia a la insulina, los niveles altos de insulina (hiperinsulina) y azúcar en la sangre (hiperglucemia) están interelacionados y ambas cosas son malas noticias.

image04

ATAQUE CARDIACO

image03

Lamentablemente el 28 de marzo de 2014 Antonio sufrió un ataque al corazón, razón por la cual le colocaron un stent en una arteria. A su ingreso en el hospital pesaba 158 libras y tenía una HbA1c del 7%. Después de su ataque cardíaco, Antonio se le indicó tomar aspirina, medicamentos para la presión arterial, una estatina, un anticoagulante y un bloqueador beta. En poco tiempo comenzó a sentir los efectos secundarios de las medicaciones múltiples. Frustrado, volvió a leer una serie de materiales de salud y medicina y dijo a sus médicos que no estaría tomando medicamentos para el resto de su vida. También vio el documental “Cereal Killers – Asesinos del Cereales”, que fue como una luz en su camino para seguir dando los pasos necesarios en los cambios de sus hábitos para su restablecimiento.

Ver este video a continuación:

https://www.youtube.com/watch?v=dON-fPp5Hy0

DIETA BAJA EN CARBOHIDRATOS

En julio de 2014 Antonio dijo a su médico de cabecera y a su cardiólogo que iba hacer una dieta baja en carbohidratos y rica en grasas. Mientras que sus médicos no le aconsejaron nada en contra de ella, eran escépticos y le advirtieron que tendría que hacerse un análisis hecho con frecuencia para controlar el impacto de la dieta. A continuación, para septiembre de 2014 Antonio recibió una llamada de su médico quien le dijo: “¡felicidades, lo que sea que está haciendo, sígalo haciendo, tiene usted un HbA1c normal!, por lo que le recomendaron dejar de tomar el medicamento Janumet y como forma de control que siguiera tomando el Metformin”. Como se muestra a continuación, el HbA1c de Antonio había bajado del 6,6% al 4,9% con el enfoque de la dieta baja en carbohidratos, también había rebajado trece libras, por lo que se encontraba ahora con 145 libras, mientras que su presión arterial se había normalizado, su HDL aumentó en 20 puntos y sus triglicéridos habían disminuido por debajo de 100 mg / dl.

image00

ELIMINANDO EL FENOMENO DEL ALBA EN LA DIABETES TIPO II

A pesar de comer sólo dos comidas bajas en carbohidratos por día, Antonio observó que a finales del 2015 sus niveles de azúcar en sangre comenzaban a dispararse hacia arriba en horas de la mañana.

El fenómeno del amanecer es el proceso en el que el cuerpo segrega una serie de hormonas y la glucosa en el torrente sanguíneo, en preparación para el día, sin embargo, si usted es resistente a la insulina entonces la respuesta de la insulina puede no ser adecuada para mantener los niveles normales de glucosa en la sangre, por lo que Antonio después de haber sufrido un ataque al corazón se tomó esto en serio y estaba dispuesto a hacer lo que fuese necesario para revertir esta situación, así que para poner en marcha el nuevo año, Antonio adoptó un régimen regular de ayuno intermitente que involucró a ir a la cama sin cenar el domingo por la noche y luego no comer hasta el martes por la noche, ofreciéndole esto una ventana de ayuno de 44 a 48 horas cada semana. La siguiente tabla muestra los números de glucosa en la sangre de Antonio hasta diciembre antes del protocolo de ayuno y luego a través de enero y febrero con el protocolo de ayuno en su lugar.

image06

La vida real de los números de la glucosa en la sangre siempre van a rebotar, sin embargo, se puede ver que los valores promedio de glucosa en sangre de Antonio han mejorado mucho. Sus números de glucosa en sangre por la mañana se muestran a continuación. “Estoy consiguiendo los mejores números que he tenido y sin fenómeno del amanecer”, dice Antonio.

image11

Mientras que los ayunos más largos están trabajando bien para Antonio, también puede utilizar períodos de ayuno más cortos regulares para mantener su glucosa en la sangre hacia abajo. Echa un vistazo a la sección: usando el medidor de glucosa en su artículo como un indicador de combustible para que obtengan algunas ideas sobre cómo puede asegurarse de que su glucosa en sangre promedio sea una tendencia en la dirección correcta.

Una forma de ver los niveles de glucosa en la sangre y el fenómeno del amanecer es la manera del cuerpo de liberar el exceso de energía almacenada en el torrente sanguíneo para ser utilizado. Si usted es resistente a la insulina del cuerpo va a utilizar un proceso llamado gluconeogénesis para convertir el exceso de proteínas, grasas e incluso hasta cierto punto, en glucosa. Una vez que el exceso de grasa de las personas disminuye, la frecuencia será más sensible a la insulina y el cuerpo detendrá el bombeo de este exceso de glucosa en el torrente sanguíneo.

HBA1C

Comenzando con una HbA1c de 5,1% se notaba que Antonio ya había realizado buenas modificaciones con los cambios en su dieta debido a su baja ingesta en carbohidratos bajo un enfoque disciplinado. Sin embargo, la adición del protocolo de ayuno le ayudó a fundar sobre una buena base y a hacer posible que sus niveles de glucosa en la sangre disminuyeran aún más que los niveles óptimos y en base a esto sus valores de glucosa en sangre ahora tienen un HbA1c de alrededor del 4,6%.

image02

CETONAS

Las cetonas de Antonio son estables, pero en realidad con tendencia a la baja después de la introducción del régimen de ayuno. El hecho de que Antonio tiene valores más bajos de cetonas no es realmente una preocupación dado que él está probablemente utilizando sus cetonas de manera más eficaz de la energía en lugar de dejar que se acumulen en la sangre como podría ser el caso con una dieta alta en grasa y sin ayuno.

image01

Creo que muchas personas se meten en problemas persiguiendo a altos valores de cetona, añadiendo más grasa dietética sin mejorar su metabolismo y la sensibilidad a la insulina, hasta el punto en que realmente puede utilizar las cetonas. El ayuno da fuerzas al cuerpo para aprender a usar cetonas como combustible.

GLUCOSA: INDICE DE CETONA

La relación entre la glucosa y las cetonas (GKI) pueden ser una medida más útil cuando los niveles de glucosa en la sangre se están reduciendo. Un GKI reductor es una indicación de que los niveles de insulina están disminuyendo y su salud metabólica está mejorando. Podemos ver en el gráfico a continuación la glucosa de Antonio: relación de cetona (GKI) que mejora cada vez que ayuna y que está en una baja tendencia con el tiempo. Estos valores bajos GKI indican que él está logrando una excelente salud metabólica.

Thomas Seyfried GKI es una herramienta útil para el seguimiento de su salud metabólica una vez que sus valores de glucosa en sangre están acercando a los niveles óptimos. Seyfried apunta a sus pacientes de cáncer para tienen una GKI de 1,0, aunque un GKI debajo de 10 se considera que es un estado de insulina bastante bajo y que en menos de tres es excelente para la salud metabólica de alguien que no esté persiguiendo una cetosis terapéutica.

¿NO HAY VUELTA A ATRÁS?

Antonio sigue disfrutando de los ayunos semanales durante el cual se centra en beber grandes cantidades de té, café y un poco de caldo de hueso, ingiere también varios suplementos dietéticos y una aspirina diaria. Su peso ahora se ha reducido a 141 libras y ha vuelto a usar la misma talla de ropa que solía llevar durante estuvo en la universidad.

Cuando sus amigos le preguntan cómo ha logrado revertir su diabetes tipo 2 y cómo ha logrado perder peso, él responde: “lo he logrado al comer una dieta baja en carbohidratos y rica en grasas en base a comer comida de verdad. Yo trabajo para mantener la mayor cantidad de mis alimentos en el rango del 70% de grasa, 20% por ciento de proteínas y un10% de carbohidratos como mis objetivos ideales. Yo miro mi ingesta de proteínas, porque el exceso convertirá a través de la gluconeogénesis. “Yo me propongo mantener este enfoque para el resto de mi vida, pues amo los resultados que esta dieta ha proporcionado a mi nuevo estilo de vida! ”

Antonio dice: Otra manera de mirar la resistencia a la insulina es su cuerpo, ya que éste le dice que usted está comiendo en exceso, ya sean demasiadas cosas inadecuadas o simplemente comer demasiado a menudo. Nuestros antepasados ​​eran cazadores recolectores cuyos hábitos de alimentación eran más como escasez y abundancia, no de tres comidas con bocadillos. Conozca y respete la insulina, ya que ésta le dirá cómo puedo hacerlo y si no atiende a sus señales le podrá causar estragos en su salud metabólica.

También puede pensar en su medidor de glucosa en sangre como indicador de combustible. Si sus niveles de glucosa en la sangre son altos, entonces podría ser el momento de dejar de llenar el depósito de combustible por un tiempo. El ayuno intermitente es como ir a un gimnasio metabólico y de trabajo. El cuerpo obtiene la oportunidad de reparar, recuperar y regenerarse si se utiliza de forma inteligente lo que hará la diferencia para su salud y para los sensibilizadores a la insulina.

Estoy decepcionado en el establecimiento médico, ya que deben saber mejor que yo lo que hay que hacer y no lo hacen. ¿Por qué no es la educación en nutrición clínica y terapéutica obligatoria en la escuela de medicina y no es enseñado con el mismo énfasis que la farmacología?

¿CURADO?

¿Antonio está curado de su diabetes tipo 2? La respuesta depende de su definición de “curado”.

¿Antonio va a ser capaz de comer comida chatarra y alimentos procesados ​​cinco veces al día? Probablemente, no, sin embargo, si Antonio mantiene este protocolo en ayunas junto con su enfoque bajo en carbohidratos entonces él podría ser capaz de mantener los niveles óptimos de glucosa en sangre sin temor a otro ataque al corazón. Si ese es su definición de “curado”, la respuesta podría ser sí.

Felicidades Antonio y mantener el gran trabajo!

what is a ‘well formulated ketogenic diet’?

While everyone uses fat for fuel to some degree, a ketogenic diet aims to reduce insulin levels to a point where ketone levels are high enough to be measured in the blood, breath or urine. [1]

In starvation, insulin levels plummet with glucose levels coming down and ketone levels increase progressively.

According to Dr Steve Phinney’s chart below, [2] a “well formulated ketogenic diet” (WFKD) contains between 3 and 20% carbohydrates and between 10 and 30% protein.  Other dietary templates such as the Mediterranean or Paleo diets typically contain more carbohydrates and less fat.

There is a lot of knowledge encapsulated into this chart, so I encourage you to take the time to digest it, or even better, take the 20 minutes to watch this video from the man himself.

The concern typically expressed about restricted carbohydrate diets is that they will not provide adequate nutrition (i.e. vitamins, minerals and amino acids).

Diabetics, along with the general population, are advised to eat in line with the USDA Food Pyramid / My Plate guidelines which emphasise “healthy whole grains” while discouraging saturated fat and cholesterol.

Diabetics are told that they should not deprive themselves of any foods or not to risk getting inadequate nutrition, but rather to “cover” any carbohydrates they eat with insulin (or treat with medications such as Metformin for type 2 diabetics).

Even in health circles ketosis is sometimes considered to be extreme and not worth the effort for most people, but is it really that hard to achieve?

When we look at the relationship between ketones, blood sugar and HbA1c we see that someone with excellent blood glucose levels will have a moderate amount of blood ketones.

The chart and table below are based on my tracking of blood sugars and ketone values.  Optimal blood (i.e. 4.6mmol/L) glucose corresponds to a ketone value of about 1.3mmol/L.

HbA1c average blood sugar ketones
 (%)  (mmol/L)  (mg/dL)  (mmol/L)
low normal 4.1 3.9 70 2.1
optimal 4.5 4.6 83 1.3
excellent < 5.0 < 5.4 < 97 > 0.4
good < 5.4 < 6.0 < 108 < 0.3
danger > 6.5 > 7.8 > 140 < 0.3

In view of this it’s hard to see why ketosis is extreme.  It’s just what happens when someone has reduced their dietary insulin load to a point where they are achieving excellent blood sugars!

Ketosis is a sliding scale.  Some people will want to push their ketone levels to therapeutic levels though fasting and a higher fat diet, but this may not be necessary for general health.

Most people would benefit from reducing their dietary insulin load to a point where their blood sugars are close to excellent.

See Diabetes 102 for more info on what your blood sugars should be and the Goldilocks Glucose Zone for more thoughts on how to manipulate your diet to get excellent blood glucose levels.

I am a big fan of Steve Phinney (I attended a masterclass with him when he was in Brisbane last year), but I think he potentially alienates people when he starts off talking about the Inuit and Steffanson living off all meat diets.

I also understand why the people generally might baulk at the idea of mainlining butter and MCT oil to drive up ketones.  “How can eating all that extra fat really be healthy?” they ask.

I propose an alternative sales pitch for ketosis:

  1. ketosis occurs when your blood sugars are close to optimal,
  2. blood sugars can be optimised by reducing the insulin load of your diet, and
  3. once you optimise your blood sugars you will reduce your hunger, access your body fat for fuel and a whole host of other health markers will improve.
