optimal meals for therapeutic ketosis

Therapeutic ketosis, which involves reducing the insulin load of our diet to increase fat burning, is an exciting adjunct therapy for a range of chronic conditions such as cancer, epilepsy and dementia.  A more aggressive ketogenic approach can also be implemented in the early stages of a low carb dietary approach to minimise blood sugars and strip excess glucose from the system.

At the same time, people using a very high fat approach need to be intentional to ensure they obtain adequate nutrition.  These meals prioritise a low insulin load while maximising nutrient density as much as possible.

The nutrient density of these meals is not as high as other approaches and hence it is ideal if you are able to transition to one of the following approaches as your metabolic health and / or blood glucose levels improve:

nutrient dense diabetic friendly vegan foods

  • Eating plant-based foods can be a great way to improve nutrient density and reduce the amount of highly insulinogenic processed carbohydrates in your diet.
  • This article looks at how we can optimize a plant-based diet for nutrient density as well as diabetic friendly by reducing insulin load.
  • Finally, we will look at whether adding additional food groups such as seafood, dairy or eggs would diminish or improve the nutrient density of a plant based approach.

nutrient density

A nutrient dense diet is key to maximizing health and satiety with a minimum of calories.  Maximising nutrient density enables our mitochondria to do more with less.

If our world is full of beneficial nutrients our body realises that there is no longer an energy crisis and is more likely to stop searching for more nutrients and lets go of our stored body fat and decrease appetite.

As detailed in the ‘Building a Better Nutrient Density Index’ article, quantifying nutrient density enables us to prioritise foods that contain the highest amount of essential nutrients that are harder to obtain.[1]

The chart below (click to enlarge) shows the percentage of the recommended daily intake of various essential nutrients provided by:

  • all 7000+ foods in the USDA foods database,
  • plant based foods, and
  • the most nutrient dense plant based foods.


Restricting ourselves to ‘plant based’ foods will improve the vitamin and mineral content of the foods we eat.  However, focusing on the most nutrient dense plant based foods allows us to improve nutrient density even further

most nutrient dense plant based foods

Listed below is a summary of the most nutrient dense plant based foods sorted by their nutrient density score.  The nutrient density score (ND) is shown for each of the foods.

As you can see from the plot below from Nutrition Data, celery, which has a very high nutrient density score (ND), will provide you with a range of vitamins and minerals equivalent to 92% of your recommended daily intake with 1000 calories and 83% of your protein intake with 1000 calories.  Keep in mind though that you would need to eat five bunches of celery to get that 1000 calories though.


The fact that broccoli has a low energy density may be a benefit if you are trying to lose weight, but perhaps would not be so helpful if you are fueling for an Ironman Triathlon.

Also shown in the tables below is the net carbohydrates and calories per 100g for each of the foods listed.

The great thing about most of these foods is that they will provide you with heaps of nutrients while having a low energy density which will make it hard to over consume them to a point that they will spike your blood glucose levels.

Listed below are the most nutrient dense plant based foods.  In the second half of this article we will look at how we can choose foods that will be more gentle on blood glucose levels for those of us that are more insulin resistant.

diabetic friendly nutrient dense vegan foods

While the foods listed above would represent a significant dietary improvement for most people, those who are insulin resistant may struggle to keep their blood glucose levels stable if they eat too much non-fibre carbohydrate that can be found in plant based foods (e.g. bread, sweet potato, quinoa, rice, beans or spaghetti).

It is hard to get too many calories and / or spike your glucose levels if you restrict yourself to vegetables like celery, broccoli and spinach.

The problem comes if you are still hungry after you have eaten your fill of non-starchy veggies and are not wanting to lose more weight.  People using a plant based approach may end up filling up on energy dense higher carbohydrate foods which are more likely to raise their blood glucose and insulin levels.

As shown in the chart below, our insulin response to food is only partially explained by the quantity of carbohydrates in our food.


The analysis of the food insulin index data indicates that our insulin response is also influenced by the fibre and the protein in the foods we eat.


We can use the formula below to estimate the amount of insulin that our food will require as shown by the formula below.  Foods with a lower insulin load will enable your pancreas to keep up with demand and maintain normal blood glucose levels without the ‘blood glucose roller coaster’.

insulin load (g)=carbohydrates (g)-fiber (g) + 0.56*protein (g)

The higher fat foods actually have a lower nutrient density than the most nutrient dense vegetarian foods listed above.  Ideally in time someone with insulin resistance would be able to restore their insulin sensitivity through eating nutrient dense, low insulin load foods along with perhaps intermittent fasting and exercise.  However, in the meantime the lower insulin load foods will enable you to maintain normal blood glucose levels.

The list of foods below is prioritised by both nutrient density and the proportion of insulinogenic calories.  These foods will provide high levels of nutrition while also being gentle on your blood glucose levels with lower levels of insulin required.


The vegetables in this list have a lower percentage of insulinogenic calories, lower amounts of net carbohydrates and a low energy density and therefore will have a minimal impact on blood glucose levels.   While the percentage of insulinogenic calories is often high, the net carbohydrates is low so the effect on blood glucose will be minimal.

nuts and seeds seeds

Nuts and seeds have a lower proportion of insulinogenic calories as well as being lower in net carbs which makes them diabetic friendly.  They do have a considerably higher energy density and hence, unlike the veggies, it is possible to overeat nuts and seeds if you’re keeping an eye on your weight.

The list of diabetic friendly fruits with a lower proportion of insulinogenic calories ends up being quite short.  Some of these fruits will raise your blood glucose levels if you eat enough of them.  So if you are particularly insulin resistant then you will want to limit your quantity of fruit or stick to the lower insulin load fruits (e.g. olives and avocados rather than mango).

what about pescetarian, lacto, ovo options?

In the development of this article I spoke with Barry Erdman who runs the Vegetarian Low Carb Diabetic Healthy Diet Society Facebook group.

Barry has been a strict vegetarian since 1970 and was diagnosed with Type 1 Diabetes nine years ago.  Barry maintained a nutrient dense plant based diet after his diagnosis, however found that he needed to incorporate dairy, eggs and some oils (e.g. MCT, coconut) into his vegetarian diet in order to achieve acceptable blood glucose control.  Barry told me that when he lost 30 lbs when he switched from a vegetarian diet to a LCHF keto lacto ovo vegetarian diet eliminating all grains, bad oils and fruit (except berries).

Barry also came to the conclusion that he would need to incorporate some fish oil into his diet in order to provide adequate levels of essential fatty acids which are not available in significant quantities in plant based products.

Barry asked me to have a look at how a lacto, ovo, pescitarian diet would stack up against the straight vegan approach.  So listed below are the most nutrient dense lacto (dairy), ovo (eggs), and pescetarian (seafood) diabetic friendly foods.


For those who are interested in adding eggs or seafood I have listed them based on their nutrient density and proportion of insulinogenic calories.

macronutrient comparison

The image below shows a comparison of the macronutrients of these different approaches compared to the average of all of the foods in the USDA foods database.

The nutrient dense vegan approach will provide a lot of of fibre which will make these foods very filling and hard to overeat, however perhaps not particularly diabetes friendly.

The diabetes friendly approach has more protein and only 30% net carbohydrates so it will have are more gentle effect on blood glucose levels.

With higher levels of fat from fish, dairy and eggs, the pescetarian approach is 40% fat which will be more gentle on the blood glucose levels of someone with diabetes.

comparison of essential micronutrients

This chart shows the nutrients provided by the vegan approach compared to the average of all the foods in the USDA database.  We get a lot of vitamin K, vitamin C and vitamin A but no omega 3 fatty acids and lower quantities of vitamin B-12.

2017-02-26 (12).png

This chart shows the nutrients contained in the diabetes friendly vegan approach.  While this approach has more fat and less carbohydrates the nutrient density is lower overall.

2017-02-26 (14).png

This chart shows the nutrient density of the pescetarian approach which is higher overall.

So in summary, there are some great nutrient dense options for people with diabetes who choose to follow a plant based dietary approach.  Supplementing a plant based diet with some seafood will provide essential fatty acids and boost protein levels.

Dominic D’Agostino’s breakfast – sardines, oysters, eggs and broccoli

At first it sounds like a bizarre food combination, but when the smartest guy in the room says that he has sardines, oysters, eggs and broccoli as his regular breakfast I wasn’t surprised to find that it scored highly in the nutritional analysis.

Before he started saving the world by progressing Warburg’s mitochondrial theory of cancer and oxygen toxicity seizures for DARPA Dominic D’Agostino studied nutrition and is rumoured to have done some bodybuilding.

Both physical and mental performance are undoubtedly critical to Dom, so it’s not surprising that he is very intentional about what he puts in his mouth to start each day.

As you can see in the plot from Nutrition Data below Dom’s breakfast scores a very high 93 in the vitamins and minerals score and a very solid 139 in the protein score.

You could say this meal was high protein (44%), low carb (10%) and moderate fat (46%), although his fatty coffee and high fat deserts would boost the fat content to make it more “ketogenic”.

Chrome Legacy Window 29122015 35453 PM.bmp.jpg

Dom’s breakfast scores well against the 250 meals analysed to date in the meal rankings for different goals coming in at:

  • therapeutic ketosis – 176
  • diabetes and nutritional ketosis – 87
  • nutrient density – 9
  • weight loss – 16

I’ve heard Dom say that he aims for a ‘modified Atkins’ approach with higher protein levels rather than a classical therapeutic ketogenic diet which is harder to stick to and might be used for people with epilepsy, cancer, dementia etc.  It was intriguing to see that Dom’s standard breakfast ranks the highest in nutrient density rather than therapeutic or nutritional ketosis.

Image result for tim ferriss dom d'agostino

Dom first mentioned his favourite breakfast concoction in his first interview with Tim Ferriss (check out the excellent three hour podcast here).   You can hear the shock and slight repulsion in Tim’s voice in the sound check as he responds with

“Do you blend that up in the Vitamix?”

But now Tim, rather than following his own slow carb approach, has made sardines and oysters a regular breakfast staple and mentions it as one of the top 25 great things he learned from podcasts guests in 2015.

The stats for a 500 calorie serve of Dom’s breakfast are shown in the table below.

net carbs

insulin load carb insulin fat protein fibre
6g 38g 18% 46% 44%



I was aware that broccoli, eggs and sardines are nutritionally amazing, but then the oysters fill out the vitamin and mineral score to take it a little bit higher.  Dom obviously understands the importance of Omega 3s which are hard to get in significant quantities from anything other than seafood.

I was surprised to see that oysters can be ‘carby’ (at 23% carbs) which is apparently due to their glucose pouch which varies in size depending when they’re harvested.

Chrome Legacy Window 30122015 52819 PM.bmp.jpg

If you wanted to skip the oysters due to taste or cost considerations, the combination of sardines, egg and broccoli still does pretty well.  This option gives less carbs, a slight decrease in the vitamin and mineral score with an slight increase in the amino acid score.

Chrome Legacy Window 30122015 54033 PM.bmp.jpg

The ranking for the sans-oyster option is:

  • therapeutic ketosis –  159
  • diabetes and nutritional ketosis –  67
  • nutrient density –  11
  • weight loss – 20

The stats for a 500 calorie serving are:

net carbs

insulin load carb insulin fat protein fibre

The combination of nutrient dense seafood with nutrient dense vegetables is hard to beat.  The chart below shows my comparison of the nutrients in the various food groups in terms the proportion of the Daily Recommended Intake (DRI) from 2000 calories (click to enlarge).


I couldn’t get any photos of Dom’s breakfast, but I did get a photo of my current go to lunch.   Each weekend I get a bunch of good quality celery and chop it up into tubs to take to work each day.  I have cans of mackerel and sardines in my drawer at work.

Celery does really well in terms of nutrient density per calorie and sardines and mackerel are high on the nutrient density lists without being outrageously expensive (e.g. caviar, anchovy, swordfish, trout).

mackerel and celery

When I feel hungry I might start munching on the celery which is pretty filling and hard to binge on.  Then if I’m still hungry I’ll have as many cans of mackerel or sardines as it takes to fill me up (which is usually 2 to 4).

At around 2pm this is my first meal of the day (other than espresso shots with cream) at around 2pm.  If I start to feel hungry before then I might check my blood glucose to see if I really need to refuel or if I think I’m hungry because I’m bored.   I’ll then go home and have an early dinner with the family around 6pm.

I’ve been known to indulge in some peanut butter with, cream, Greek yogurt or even butter if I’m still hungry (e.g. if I’ve ridden to work) but I try to not overdo it as I’m not as shredded as Dom yet.

The simple combination of celery and mackerel also does pretty well in the ranking of 250 meals and aligns well with my current goal of maximising nutrient density and ongoing weight loss now that I’ve been able to stabilise my blood glucose levels.

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.


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.


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.


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]  


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.


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.


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.


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.


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.


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!


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!


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.


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.


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.


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.


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]


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.


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.


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!


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


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.


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.

The table below shows this in US units (mg/dL).

70th percentile




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.


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.


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).


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.


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.


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.


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.


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.)

breakfast of champions

My Facebook feed has been flooded lately with stories about Tour de France cyclists going low carb.[1]


Or is it high protein?[2]


Whatever is going on, it seems helps them run well too![3]


While I’m not sure you can say that these elite cyclists have eschewed all carbohydrate-containing foods,  the trend away from processed carbs to whole foods is intriguing.

So if they’re going low carb does it mean they’re now butter, cream, MCT oil after starting the day with BPC?

Dr. James Morton, head of nutrition at Team Sky and an associate professor in the Faculty of Science at Liverpool John Moores University explains:[4] [5] [6] [7] [8]

We promote a natural approach to food.  Our riders eat food that grows in the ground or on a tree and protein from natural sources.

They need energy, but they also have to stay lean and healthy with a strong immune system. A natural diet is the best way to achieve this.

Fat is important for everything from energy release and muscle health to immunity, but by eating the right food the fat takes care of itself.  The riders eat eggs, milk, Greek yogurt, nuts, olive oil, avocados and some red meat for a natural mix of saturated and unsaturated fats.”

To achieve optimal weight Dr Morton asks the riders to “periodise” their carb intake by eating more when they train hard and cutting back when they’re less active.

They routinely train in the morning after eating a protein-rich omelette, instead of carbohydrate-dense bread, to encourage their bodies to burn fat for fuel.[9]


So how does low carb real food thing work?

According to Dr Terry Wahls it seems that nutrient density is a key part of maximising energy output.

To produce ATP efficiently, the mitochondria need particular things.  Glucose or ketone bodies from fat and oxygen are primary.  

Your mitochondria can limp along, producing a few ATP on only these three things, but to really do the job right and produce the most ATP, your mitochondria also need thiamine (vitamin B1), riboflavin (vitamin B2), niacinamide (vitamin B3), pantothenic acid (vitamin B5), minerals (especially sulfur, zinc, magnesium, iron and manganese) and antioxidants.  Mitochondria also need plenty of L-carnitine, alpha-lipoic acid, creatine, and ubiquinone (also called coenzyme Q) for peak efficiency.  

If you don’t get all these nutrients or if you are exposed to too many toxins, your ATP production will become less efficient, which leads to two problems:

Your body will produce less energy so they may not be able to do everything they need to do.

Your cells will generate more waste than necessary in the form of free radicals.

Without the right nutrient sources to fuel the ATP production in the mitochondria – which in turn produce energy for the cellular processes required to sustain life – your mitochondria can become starved.  The cells then can’t do their job as effectively.[10] 

So let’s look at the macro and micronutrient analysis of Chris Froome’s “rest day breakfast” (pictured above).   The analysis indicates that it does very well in both the vitamins and minerals score as well as the amino acids score.


If we throw in some spinach Froomey would improve the vitamin and mineral score of his breakfast even further.  The addition of spinach increases the nutrient balance score from 57 to 77 while the amino acid score stays high.


Froome’s wife says eating more protein has been one of the keys to losing weight and building muscle leading up to the tour.[11]  Getting a quarter of your calories from protein is more than the 16% most people consume, however with 65% of the energy coming from fat you could also call this meal low carb, high fat, or even “ketogenic” depending on which camp you’re in.


This simple but effective meal would be a pretty good option for just about anyone.  Froome’s breakfast ranks well regardless of your goals.  Based on the ranking system of meals for different goals it comes in at:

  • #10 (with spinach) and #31 (without spinach) out of 245 meals analysed for the low carb diabetes ranking,
  • #18 and 52 on the therapeutic ketosis ranking, and
  • #26 and 64 on the overall nutrient density ranking.


It seems it’s not just the low carbers, “ketonians”[12] and people battling diabetes who are training their bodies to burn fat more efficiently.  Maximising your ability to burn fat is critical even if you are extremely metabolically healthy.

The chart below shows comparison of the fat oxidation rate of well trained athletes (WT) versus recreationally (RT) athletes (who are not necessarily following a low carb diet).[13]  The well trained athletes are clearly oxidising more fat, which enables them to put out a lot more power (measured in terms of their VO2max).   It seems that you ability to efficiently burn fat for fuel it a key component of what sets the elite apart from the amateurs whether you call yourself vegan, ketogenic or a fruitarian.[14]


While carbohydrates help to produce maximal explosive power, it seems that the glucose turbocharger works best when it sits on a big power fat fueled motor.  According to Peter Defty (who spent the last couple of years helping 2016 Tour de France second place getter Romain Bardet refine his ability as a fat adapted athlete using his Optimised Fat Metabolism protocol), fat can yield more energy more efficiently with less oxidative stress which requires less recovery time.[15]

Dr Morton also understand the importance of keeping carbohydrates low to maximise mitochondrial biogenesis and to access fat stores.  If you want to learn more about his thinking on the use of diet to drive mitochondrial biogenesis you might be interested in checking out his array of published papers on the topic.[16] [17] [18] [19] [20] [21] [22]   On the topic of carbohydrate intake Morton says:

Amateur riders are taught the importance of carbohydrates for training and racing, perhaps too much actually.

From our research at Liverpool John Moores University, we now know that deliberately restricting carbs around carefully chosen training sessions can actually enhance training adaptations.

But then of course we must ensure higher carbohydrate intakes for key training sessions and hard stages in racing.

I believe this concept of periodising daily carbohydrate intake is the most exciting part of sports nutrition in the last decade and our challenge now is to address how best we do this practically.

Essentially, exercising your mitochondria in a low insulin and low glucose state forces your body to adapt to using fat for fuel and to use glucose and oxygen efficiently and effectively.[23] [24]


Not only is this useful for endurance athletes and people battling diabetes, training your body to use fat and oxygen more effectively is also claimed to be important to minimise anaerobic fermentation which is said to increase your risk of cancer.[25] [26] [27]

Many of us struggle trying to cope in an environment of excess energy from low nutrient density highly insulinogenic food.  If we can’t obtain the necessary nutrients from our food to efficiently produce energy our bodies seek out more and more food in the hope of finding the required nutrients and enough energy to feel OK.


Our bodies do their best to use the energy that we give them, but they are working overtime to pump out insulin to store the excess energy that is not used.  Over time our bodies adapt by becoming resistant to insulin in order to stop the excess energy being stored in our liver, pancreas and eyes when our fat stores on our muscles and belly can’t take any more.[28]  Then to overcome the insulin resistance the body has to pump out more insulin which makes even less of the energy we eat available for use.


When we call on our mitochondria to produce intensive bursts of energy with minimal fuel (i.e. fasting) or glucose (i.e. low carb) we force our bodies to more efficiently the limited carbohydrate.  Suddenly our bodies become insulin sensitive.

Recent studies indicate that people who are fat adapted are able to mobilise higher rates of fat at higher excercise intensities.[29]


With a higher reliance on fat they are able to conserve the precious glucose for explosive efforts.


Then, when they really need the power they have both fuel tanks available to cross the  line first… and second!
