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.

energy density, food hyper-palatability and reverse engineering optimal foraging theory

In Robb Wolf’s new book Wired to Eat he talks about the dilemma of optimal foraging theory (OFT) and how it’s a miracle in our modern environment that even more of us aren’t fat, sick and nearly dead.[1]

But what is  optimal foraging theory[2]?   In essence it is the concept that we’re programmed to hunt and gather and ingest as much energy us we can with the least amount of energy expenditure or order to maximise survival of the species.

In engineering or economics this is akin to a cost : benefit analysis.  Essentially we want maximum benefit for minimum investment.

image13

In a hunter gatherer / paleo / evolutionary context this would mean that we would make an investment (i.e. effort / time / hassle that we could have otherwise spent having fun, procreating or looking after our family) to travel to new places where food was plentiful and easier to obtain.

In these new areas we could spend as little time as possible hunting and gathering and more time relaxing.  Once the food became scarce again we would move on to find another ‘land of plenty’.

The people who were good at obtaining the maximum amount of food with the minimum amount of effort survived and thrived and populated the world, and thus became our ancestors.  Those that didnt’ didn’t.

You can see how the OFT paradigm would be well imprinted on our psyche.

OFT in the wild

In the wild, OFT means that native hunter gatherers would have gone bananas for bananas when they were available…

image28

… gone to extraordinary lengths to obtain energy dense honey …

image16

… and eaten the fattiest cuts of meat and offal, giving the muscle meat to the dogs.

image02

OFT in captivity

But what happens when we translate OFT into a modern context?

image09

Until recently we have never had the situation where nutrition and energy could be separated.

In nature, if something tastes good it is generally good for you.

Our ancestors, at least the ones that survived, grew to understand that as a general rule:

 sweet = good = energy to survive winter

But now we have entered a brave new world.

image19

We are now surrounded by energy dense hyperpalatable foods that are designed to taste good without providing substantial levels of nutrients.

image05

Our primal programming is defenceless to these foods.  Our willpower or our calorie counting apps are no match for engineered foods optimised for bliss point.

image14

These days diabetes is becoming a bigger problem than starvation in the developing world due to a lack of nutritional value in the the foods they are eating.[3]

The recent industrialisation of the world food system has resulted in a nutritional transition in which developing nations are simultaneously experiencing undernutrition and obesity.

In addition, an abundance of inexpensive, high-density foods laden with sugar and fats is available to a population that expends little energy to obtain such large numbers of calories.

Furthermore, the abundant variety of ultra processed foods overrides the sensory-specific satiety mechanism, thus leading to overconsumption.”[4]

what happens when we go low fat?

So if the problem is simply that we eat too many calories, one solution is to reduce the energy density of our food by avoiding fat, which is the most energy dense of the macronutrients.

Sounds logical, right?

The satiety index demonstrates that there is some basis to the concept that we feel more full with lower energy density, high fibre, high protein foods.[5] [6]   The chart below shows how hungry people report being in the two hours after being fed 1000 kJ of different foods (see the low energy density high nutrient density foods for weight loss article for more on this complex and intriguing topic).

image21

However the problem comes when we focus on reducing fat (along with perhaps reduced cost, increased shelf life and palatability combined with an attempt to reach that optimal bliss point[7]), we end up with cheap manufactured food like products that have little nutritional value.

image10

Grain subsidies were brought in to establish and promote cheap ways to feed people to prevent starvation with cheap calories.[8]  It seems now they’ve achieved that goal.[9]

image07

Maybe a little too well.

image01

The foods lowest in fat however are not necessarily the most nutrient dense.     Nutritional excellence and macronutrients are are not necessarily related.

In his blog post Overeating and Brain Evolution: The Omnivore’s REAL Dilemma Robb Wolf says:

I am pretty burned out on the protein, carbs, fat shindig. I’m starting to think that framework creates more confusion than answers.

Thinking about optimum foraging theory, palate novelty and a few related topics will (hopefully) provide a much better framework for folks to affect positive change. 

The chart below shows a comparison of the micronutrients provided by the least nutrient dense 10% of foods versus the most nutrient dense foods compared to the average of all foods available in the USDA foods database.

image18

The quantity of essential nutrients you can get with the same amount of energy is massive!  If eating is about obtaining adequate nutrients then the quality of our food, not just macronutrients or calories matters greatly!

Another problem with simply avoiding fat is that the foods lowest in fat are also the most insulinogenic, so we’re left with foods that don’t satiate us with nutrients and also raise our insulin levels.  The chart below shows that the least nutrient dense food are also the most insulinogenic.


what happens when we go low carb?

So the obvious thing to do is eliminate all carbohydrates because low fat was such a failure.  Right?

image20

So we swing to the other extreme and avoid all carbohydrates and enjoy fat ad libitum to make up for lost time.

The problem again is that at the other extreme of the macronutrient pendulum we may find that we have limited nutrients.

The chart below shows a comparison of the nutrient density of different dietary approaches showing that a super high fat therapeutic ketogenic approach may not be ideal for everyone, at least in terms of nutrient density.  High fat foods are not always the most nutrient dense and can also, just like low fat foods, be engineered to be hyperpalatable to help us to eat more of them.

image24

The chart below shows the relationship (or lack thereof) between the percentage of fat in our food and the nutrient density.   Simply avoiding or binging on fat does not ensure we are optimising our nutrition.

image12

While many people find that their appetite is normalised whey they reduce the insulin load of their diet high fat foods are more energy dense so it can be easy to overdo the high fat dairy and nuts if you’re one of the unlucky people whose appetite doesn’t disappear.

what happens when we go paleo?

So if the ‘paleo diet’ worked so well for paleo peeps then maybe we should retreat back there?  Back to the plantains, the honey and the fattiest cuts of meat?

image27

Well, maybe.  Maybe not.

image06

For some people ‘going paleo’ works really well.  Particularly if you’re really active.

Nutrient dense, energy dense whole foods work really well if you’re also going to the CrossFit Box to hang out with your best buds five times a week.

image11

But for the rest of us that aren’t insanely active, then maybe simply ‘going paleo’ is not the best option…

image25

… particularly if we start tucking into the energy dense ‘paleo comfort foods’.

image03

If we’re not so active, then intentionally limiting our exposure to highly energy dense hyperpalatable foods can be a useful way to manage our OFT programming.

enter nutrient density

A lot of people find that nutrient dense non-starchy veggies, or even simply going “plant based”, works really well, particularly if you have some excess body fat (and maybe even stored protein) that you want to contribute to your daily energy expenditure.

image15

Limiting ourselves to the most nutrient dense foods (in terms of nutrients per calorie) enables us to sidestep the trap of modern foods which have separated nutrients and energy.  Nutrient dense foods also boost our mitochondrial function, and fuel the fat burning Krebs cycle so we can be less dependent on a regular sugar hit to make us feel good (Cori cycle).

Limiting yourself to nutrient dense foods (i.e. nutrients per calorie) is a great way to reverse engineer optimal foraging theory.

image04

If your problem is that energy dense low nutrient density hyperpalatable foods are just too easy to overeat, then actively constraining your foods to those that have the highest nutrients per calorie could help manage the negative effects of OFT that are engrained in our system by imposing an external constraint.

image22

But if you’re a lean Ironman triathlete these foods are probably not going to get you through.  You will need more energy than you can easily obtain from nutrient dense spinach and broccoli.

optimal rehabilitation plan?

So while there is no one size fits all solution, it seems that we have some useful principles that we can use to shortlist our food selection.

  1. We are hardwired to get the maximum amount of energy with the least amount of effort (i.e. optimal foraging theory).
  2. Commercialised manufactured foods have separated nutrients from food and made it very easy to obtain a lot of energy with a small investment.
  3. Eliminating fat can leave us with cheap hyperpalatable grain-based fat free highly insulinogenic foods that will leave us with spiralling insulin and blood glucose levels.
  4. Eating nutrient dense whole foods is a great discipline, but we still need to tailor our energy density to our situation (i.e. weight loss vs athlete).

the solution

So I think we have three useful quantitative parameters with which to optimise our food choices to suit our current situation:

  1. insulin load (which helps as to normalise our blood glucose levels),
  2. nutrient density (which helps us make sure we are getting the most nutrients per calorie possible), and
  3. energy density (helps us to manage the impulses of OFT in the modern world).

I have used a multi criteria analysis to rank the foods for each goal.  The chart below shows the weightings used for each approach.

The lists of optimal foods below have been developed to help you manage your primal impulses.  The table below contains links to seperate blog posts and printable .pdfs for a range of dietary approaches that may be of interest depending on your goals and situation.

the most nutrient dense autoimmune friendly foods

An “autoimmune disease” develops when your immune system, which defends your body against disease, decides your own healthy cells are foreign.  As a result, your immune system attacks healthy body cells.[1]

The list of diseases that are said to be autoimmune related are extensive,[2] [3] and to add insult to injury, people with autoimmune issues often end up with challenging digestive issues.

An autoimmune dietary protocol eliminates foods that can trigger inflammation in people with more sensitive digestion that may be autoimmune related.  The foods typically eliminated include nuts, seeds, beans, grains, artificial sweeteners, dairy, alcohol, chocolate and nightshades.

The remaining foods largely involve vegetables, seafood and animal products.  Given that Type 1 Diabetes is an autoimmune condition I have also created a lower insulin load diabetes friendly autoimmune list of foods that that will be more gentle on blood glucose levels.

Although sticking to the autoimmune friendly list of foods is somewhat restrictive it is a very nutrient dense approach compared to other options as you can see in the comparison of the nutrient density of different nutritional approaches in the chart below where it came in at #2 of the thirteen approaches analysed.  The nutrients provided by these foods in comparison to the USDA foods database is shown below.

2017-02-18 (3).png

The nutrient density of the diabetes friendly list is shown below.

2017-02-18 (4).png

An autoimmune protocol is often a short term ‘reset’ where inflammatory foods are eliminated for a period.  Once things settle down potential other possible trigger foods are slowly reintroduced to see which foods can be tolerated.

For more information see Robb Woolf’s The Paleo Solution, Sarah Ballantyne’s The Paleo Approach or Chris Kresser The Paleo Cure.

The foods listed below represent the top 10% of the USDA food database using this ranking system.  Also included in the table are the nutrient density score, percentage of insulinogenic calories, insulin load, energy density and the multicriteria analysis score (MCA) that combines all these factors.

nutrient dense foods for weight loss and insulin resistance

I found a number of people that were using the a combination of the optimal foods for diabetes and nutritional ketosis and the optimal foods for weight loss lists.  So I thought it would be useful to combine the two approaches into a single list of foods for people who want to lose weight but who were still somewhat insulin resistant.

optimal foods for diabetes and nutritional ketosis

The food ranking system revolves around manipulating these three parameters to suit different goals:

The optimal foods for diabetes and nutritional ketosis list has a low insulin load, is fairly low in non-fibre carbs and moderately high fat while still being as nutrient dense as possible.

This approach suits someone who has Type 1 Diabetes or is lean and looking to achieve nutritional ketosis.  People who are at their goal weight can afford to eat a little more added dietary fat.

img_7321-1

While  most people looking to manage their blood glucose levels limit their carbohydrates to some arbitrary number that works for them, maximising nutrient density as well will help you to improve your mitochondrial function and increase your energy levels to ideally overcome your insulin resistance.  Maximising nutrient density also means that your body won’t keep on seeking out more and more food to obtain the nutrients it requires.

People who are very insulin resistant often do well on a higher fat dietary approach initially to let the insulin levels drop, however they often find further success in the long term if they drop their dietary fat to let more fat come from their body.

optimal foods for weight loss

The optimal foods for weight loss list is fairly low in dietary fat to allow for to come form the body during weight loss.  It’s heavy in lean proteins and non-starchy veggies and is VERY nutrient dense.  The chart below shows a comparison of a range of dietary approaches with the insulin sensitive weight loss approach being having the highest nutrient density while the diabetes and nutritional ketosis approach comes in at #8 of thirteen.

2016-10-16-4

This list of foods may look like a low fat dietary approach, but it’s not really low fat once you factor in your body fat.  The chart from Steve Phinney illustrates how your body fat makes a contribution to the weight loss phase of a well formulated ketogenic diet.

2016-10-10 (1).png

The weight loss list of foods is also quite bulky (i.e. lots of fibre and water) so they would be very hard to overeat if you stick to just these foods.  The chart below show a comparison of the various approaches with the weight loss approach having the lowest energy density.

2016-10-16-6

Eating from the weight loss foods basically equates to a protein sparing modified fast (which is widely held to be the most effect way to lose weight in the long term) meaning that will fill you up so much you won’t be above to overeat while at the same time providing enough protein to preserve lean muscle mass during the weight loss phase.

The “problem” with the aggressive weight loss approach is that it is very low in energy dense comfort foods and it is higher in carbohydrates and protein than most low carbers might be used to, so it might be harder to stick to.  It may also raise your blood glucose levels if you’re still somewhat insulin resistant.

finding the optimal balance between the extremes

I have designed this list of foods for people who are insulin resistant and also looking to lose weight provides a balance between both extremes – high nutrient density, lowish levels of dietary fat and lower energy density.

The foods listed below represent the top 10% of the USDA food database using this ranking system.  I’ve included the nutrient density score, percentage of insulinogenic calories, insulin load (per 100g), energy density (per 100g) and the multicriteria analysis score score (MCA) that combines all these factors.

The chart below shows the amount of each nutrient provided by the more balanced approach compared to average of all the foods in the USDA food database.  As you can see you will still be able to obtain heaps of nutrients while the fat comes from your body.
