is ‘too much protein’ on keto really a thing?

  • There is a lot of confusion in keto land about ‘excess protein’.
  • Insulin and protein are used to build and repair your muscles, organs and the other important parts of your body.  This is an important and beneficial use of protein and insulin.
  • Foods that contain the harder to find nutrients (e.g. potassium, magnesium, choline, vitamin D) typically contain plenty of protein.
  • Actively avoiding protein and can lead to a less nutritious diet.
  • Unless you require therapeutic ketosis for the treatment of cancer, epilepsy, Alzheimers, Parkinson or dementia, you should be chasing vitality, health and nutrition along with stable blood sugar levels rather than some arbitrary ketone level.
  • There are a range of different ways to quantify protein intake.  Thinking in terms of percentages can be more confusing than helpful.
  • It’s hard to over-consume protein because it is highly satiating.  However, if you avoid protein your body may drive you to consume more calories until you get the protein it needs.
  • If you follow your appetite and focus on foods that contain the vitamins and minerals you need you will probably get enough protein.

Virta Facebook Live Q&A

I recently had the opportunity to pose some questions about protein intake to the Godfather of Keto, Dr Stephen Phinney in a recent Facebook live Q&A.

image16

Dr Phinney’s response to my question is shown below, including his recommended protein intake levels of 1.2 to 1.75 g per kg reference body weight of protein.

image10.jpg

While I largely agree with Dr Phinney’s response, I think it’s worth elaborating on some of the issues that are causing so much confusion at the moment.

Will too much protein kick me out of ketosis?

If you’ve read previous posts on Optimising Nutrition you’ve probably seen my analysis of the food insulin index data that shows that our carbohydrate intake alone doesn’t explain our insulin response to food.

The food insulin index data shows that our insulin response to food is more accurately predicted when we consider the fibre and protein content of our food, not just the carbohydrate.

However, I fear that many people have used the insulin load concept as a reason to avoid protein.  I now understand that this is far from optimal within the broader context of good nutrition for health, weight loss and vitality.

If you are interested in learning more the implications of the insulin index data I recommend you check out the following articles:

Effect on blood sugar and insulin

While trading your calories from butter for steak will increase your requirement for insulin, the food insulin index data suggests that as a general rule, getting more of your energy from protein will reduce your insulin requirements as it forces out processed carbohydrates as shown in the chart below.

image46.png

Getting more energy from protein tends to decrease our glucose response as it forces out nutrient-poor refined high carb foods.  Your body can convert protein to glucose (i.e. gluconeogenesis) if it really needs to but it’s a lot of work, so it would much rather get energy from carbs or fat.

image49.png

Protein is also very satiating.  Once we have enough protein, our body tends to crave more fatty and carby foods for energy.[10] 

While it is both financially and metabolically expensive, protein is the most important component of your diet.  Different people will need different amounts of protein depending on their life stage and activity levels.

While you probably don’t need to be going out of your way to binge on more protein than you can comfortably consume, actively avoiding protein containing foods is a recipe for nutritional disaster.  If you are exercising or lifting heavy then you will naturally crave more protein.

If you actually need higher levels of blood ketones for therapeutic ketosis, it may be a good strategy to consciously restrict protein.  However, I don’t’ think the vast majority of people chasing ketones are looking for therapeutic keto for the management of cancer, Alzheimer’s, epilepsy, dementia or Parkinson’s but rather fat loss or diabetes control.

Protein number crunching

The numbers around protein can be confusing due to the units used.

  • Dr Phinney uses ‘reference body weight’ (RW) (which he says is ‘the weight you were when you were in college’).
  • The mainstream nutrition world talks in terms of total body weight (BW).
  • Meanwhile, the sports nutrition community talk in terms of lean body mass (LBM).

In order to understand what this means in practice, let’s look at an example of a woman who is currently 40% body fat but was 25% in college (i.e. her reference weight).  For argument’s sake let’s say she was 70 kg in college but she is currently 87 kg or 193 lb.  The images below will give you an idea of what these level of body fat levels look like.

image45.jpg

In the table below I have calculated what Dr Phinney’s recommended protein intake looks like for this person in terms of:

  • reference body weight (RW),
  • lean body mass (LBM), and
  • body weight (BW).

Based on Dr Phinney’s guidance, this person should be eating between 84 and 123 g of protein per day.

  body fat weight (kg) weight (lbs) lower limit upper limit
reference weight 25% 70 154 1.2 g/kg RW 1.75 g/kg RW
lean body mass 0% 52.5 116 1.6 g/kg LBM 2.3 g/kg LBM
body weight 40% 87.5 193 1.0 g/kg BW 1.4 g/kg BW
protein (g/day)       84 123

On a practical note, there is nothing low about 2.3 g/kg LBM protein.  While I do track my intake I find it hard to get above 2.2 g/kg LBM even when trying to maximise protein.  At the same time, the lower limit is well above the official Recommended Daily Intake of 0.84 g/kg for men and 0.75 g/kg for women which are set to maintain nitrogen balance and prevent disease (i.e. not achieve optimal health and vitality).

What about percentages?

Talking about protein in terms of percentages of energy intake can be confusing as it depends on your activity levels or whether you are dieting.   Theoretical energy intake requirements are based on your lean body mass and activity levels.

The table below shows what Dr Phinney’s protein recommendation of 1.2 to 1.75 g/kg RW (or 1.6 to 2.3 g/kg LBM) look like for our hypothetical woman above in terms of percentage of energy intake for different energy intakes depending if she was trying to lose weight, maintain weight or was more active.

scenario calories lower upper
30% deficit 1158 29% 42%
sedentary 1654 20% 30%
lightly active 1852 18% 27%
moderately active 2084 16% 24%
vigorously active 2431 14% 20%
protein (g)   84 123

Protein intake in terms of percentage energy intake can vary widely to the point that it’s practically useless.  It’s generally much more useful to talk in terms of protein intake in grams per weight lean body mass rather than percentages.

Protein and nutrient density

Since stumbling across the insulin index, one thing I have found consistently is that nutrient-dense foods are not low in protein.

If you are focusing on the foods that contain the harder to find nutrients (e.g. magnesium, magnesium, choline, vitamin D etc) you will be getting plenty of protein.

Conversely, the only way to really get the ultra-low protein intakes being recommended by many people without an energy deficit is to avoid most solid foods and prioritise macadamia nuts, butter and oils.  It should not be a surprise that it will be hard to get a broad spectrum of essential nutrients with this sort of dietary approach.

As shown in the chart below, nutrient density tends to increase up to about 50% of energy intake.   If you’re eating more than 50% protein you’re likely relying on processed foods and supplements.[11]

image20.png

The chart below shows the nutrient profile of the most nutritious foods in the USDA database.  If you could stick to these foods you would easily be getting a lot of the essential nutrients without having to consume too much energy.

image17.png

The problem with these foods is that they can be very satiating which makes it hard to get enough energy in if you are active.  However, if you are trying to lose weight these foods may help to ensure that you are getting the nutrients you need with less energy without being hungry.

It’s interesting to see many people who have been experimenting with the Nutrient Optimiser have commented on how little food they can get away with while experiencing minimal levels of hunger.   Nutrient dense foods tend to be hard to overeat and also provide you with the nutrients to prevent cravings and hence reduce appetite.

For comparison, the chart below shows the nutrient profile of the ketogenic diet foods.  That is, the foods that have the lowest percentage insulinogenic calories.   These foods are 80% fat, 15% protein and 3% net carbs).  Ironically, an individual consuming these foods will be meeting the minimum levels of protein but they will be missing out on a large number of other vitamins and minerals.

I find that it’s often the people who are trying to actively avoid protein that find themselves at the bottom of the Nutrient Optimiser Leaderboard with a very poor nutrient profile.

The chart below shows the nutrient profile that we get when we actively avoid protein.  The only nturients that we get enough of in this scenarios is sodium and vitamin C!

Unless you are chasing therapeutic ketosis for the treatment of cancer, epilepsy, Alzheimers or dementia I think your focus should be on building health and maximising nutrition rather than higher ketone values.

If you are getting the micronutrients you need to thrive you will be getting plenty of protein and won’t need to worry too much about getting adequate protein intake.  Conversely, if you are actively avoiding protein you will be unnecessarily sacrificing your other micronutrients (especially if you are replacing your calories from protein and carbs with refined fat).

But will too much protein kick me out of ketosis?

As I write this I have been experimenting with adequate protein with less fat and carbs and maximal nutrients on the Ketogains Bootcamp.  A typical daily Cronometer summary is shown below.

image24.png

My protein is sitting at about 2.2g/kg LBM for me given that I’ve been spending a lot of time in the gym lifting heavy during this time.  I’ve also been able to hit many of the nutrients targets while maintaining a significant calorie deficit.

Leading up to this period my blood glucose levels were sitting in the mid 5s (approx 100 mg/dL).  However, once I introduced the energy deficit my glucose levels plummet to the mid 4s (approx 80 mg/dL).

image21.jpg

And although I don’t worry much about ketones, they seem to be sitting at around 0.7 mmol/L, which I’m pretty happy with.

I know if I keep my blood glucose around this level I will continue to lose weight and continue to improve my glucose control and HbA1c.

I also get plenty of breath acetone from endogenous ketones as shown on my Ketonix below.

image32.png

Don’t forget the basal insulin!

While there has been a lot of focus on what we can do to not have too much insulin, we need to remember that insulin has a number of important roles including:

  1. to help us get glucose into cells to be used by our mitochondria,
  2. to help build and repair our muscles, and
  3. to control the release of glucose from our liver while the energy in our bloodstream is used up.

People with type 1 diabetes demonstrate happens if we don’t have enough insulin.  Not only would we not be able to store the energy we eat as fat and muscle, the brake comes off the liver and all the stored energy in our body comes flowing out in the form of excess glucose and ketones (i.e. diabetic ketoacidosis).

The image below is the same child, “J.L.”, in the 1920s before and after receiving insulin therapy.  In a healthy person, insulin suppresses the fuel flow from the liver to healthy levels.

In someone on a standard western diet, basal insulin represents about 30% of the today daily dose.  Basal insulin drops to about 50% for someone on a low carb or keto diet.  But you can never drop your insulin requirements to zero.  You always need this basal to stop the uncontrolled flow of fuel from your liver into your bloodstream.

We focus so much on the effect of the food we eat but we forget that it’s also the excess fuel on your body and floating around in our bloodstream that also plays a massive role in the insulin demand on our pancreas.

Whenever there are high levels of energy sitting in our bloodstream (from glucose, ketones or fat) the pancreas has to ramp up basal insulin production until the fuel in our bloodstream is used up.  The more fat there is on our body the harder our pancreas has to work to hold back the pressure of excess fat on our body from being released into our bloodstream.

So, you may believe that your mug of Bulletproof coffee or the fat bomb may not be raising your insulin levels because it does not contain glucose or protein.  However, your pancreas is still working overtime to produce more insulin to hold the fat on your bum and until the energy coming in via your mouth is used up.

You may be able to ramp up your energy expenditure for a while by shivering and fidgeting, more but after a time of overdriving energy you’ll likely end up fat and insulin resistant.

If you really want to reduce your insulin levels you need to work on reducing the excess level of energy floating around in your bloodstream (from any source, including fat, carbs, protein or exogenous ketones) so your pancreas will decrease its production of insulin to allow body fat to be used.

Focusing on obtaining the nutrients you need without too much energy seems like common sense to me.

Therapeutic ketosis

Someone targeting therapeutic ketosis to assist with the management of chronic conditions such as cancer, epilepsy, dementia or Alzheimer’s may benefit from higher levels of ketosis and less reliance on glucose.  But I don’t think the vast majority of people who are Googling “keto” at the moment are looking for a therapeutic treatment.

therapeutic keto

Understanding how to quantify the insulin load of our food enables us to accurately tailor or food choices to suit our goals.  When it comes to insulin load we need to keep it low enough to get the results we need without compromising the nutritional value of the food we eat too much.

The chart below shows that nutrient density peaks at around 40% insulinogenic calories.

  • If you are insulin resistant it would be prudent to have less than 40% insulinogenic calories.
  • Someone on a low carb diet might have less than 25% insulinogenic calories.
  • Someone targeting therapeutic keto will likely need to have less than 15% insulinogenic calories to see therapeutic levels of ketones.

image33.png

Unless you really require therapeutic keto then I don’t think there is a need to worry too much about the impact of protein on your blood ketone levels.  Actively avoiding protein tends to lead to compromising nutrient density unnecessarily which may lead to nutrient cravings or deficiencies in the long term.

The glucose : ketone index

People who require therapeutic ketosis should also ensure that they are not driving the total energy in their system too high.  To do this they can track their glucose as well as ketones.  The glucose:ketone ratio (GKI) which was developed by Dr Thomas Seyfried to measure the degree of therapeutic ketosis.[12]

If you’re interested, your GKI can be calculated by dividing your glucose (in mmol/L) by your ketone values.  For example, if your blood glucose is 108 mg/dL and your blood ketones are 0.5mmol/L, GKI = blood glucose / ketone = (108 mg/dL / 18) / 0.5 mmol/L = 6 mmol/L / 0.5mmol/L = 12.

People who are chasing therapeutic ketosis typically do not need to worry about ingesting too much energy.   Driving a hypercaloric state with refined fats is not a major concern for someone trying to keep weight on (e.g. cancer cachexia).  However, ensuring that they are achieving lower glucose levels will ensure that they are not driving insulin resistance.

For reference, the table below shows the relationship between HbA1c, average glucose, ketones and GKI for different scenarios showing how your GKI and ketones correlate with HbA1c and blood glucose.

 metabolic health HbA1c average blood glucose blood ketones GKI
 (%)  (mmol/L)  (mg/dL)  (mmol/L)  
low  4.1 3.9 70 > 0.3 < 4
optimal 4.5 4.6 83 > 0.3 < 15
excellent < 5.0 < 5.4 < 97 > 0.3 < 20
good < 5.4 < 6 < 108 < 0.3 < 40
danger > 6.5 7.8 > 140 < 0.3 > 40

Really low GKI values (i.e. very high ketones and very low glucose) are typically seen in extended fasting when glucose levels to drop and ketones from body fat increase in a low insulin state.

The chart below shows my blood ketone and glucose levels during a seven day fast.  Amazingly, as my blood glucose levels dropped below 4.0 mmol/L my ketones drifted up to 8 mmol/L.  During more recent, however, I haven’t been able to achieve such high ketone levels.

While we can get these high ketone levels during fasting, we typically don’t see them in the fed state.  To give you an idea of what to expect, the chart below shows GKI values over time during fasting for RD Dikeman (from Type 1 Grit), Jimmy Moore, Simon Saunders (Keto Island) and myself.   As a rule of thumb, you might expect to see a GKI value less than 2 after two or three days of water fasting.

Nutrient density analysis

Being a big fan of Dr Phinney and the Art and Science books, I couldn’t help running his recommended diet through the Nutrient Optimiser.  I entered all the meals in the Art and Science of Low Carb Living into Cronometer and ran it through the Nutrient Optimiser.

image5.jpg

If you’re interested, you can see the full report here and where these meals rank on the leaderboard here.

So what should you do with all this information?

So, to summarise:

  1. If you have great blood sugars and just want to lose weight then you should focus on maximising nutrient density while reducing the energy levels in your bloodstream.  There is no need to worry about “being in ketosis”.  You will produce ketones if you are successfully achieving an energy deficit and burning your own body fat stores.
  2. If you are insulin resistant then you will want to limit your insulin load to a maximum of 2.9 g/kg LBM.  This will restrict carbohydrates in your diet so your blood sugars stabilise.
  3. If you are trying to manage diabetes then you want to keep your insulin load under 1.8 g/kg LBM.  This will restrict carbohydrates and may reduce your protein intake a little.
  4. If you require therapeutic keto then you will want to keep your insulin load less than 1.1 g/kg LBM and may need to consider limiting protein.

The recommended values for protein and insulin load are shown in the table below.

approach

min protein

(g/kg LBM)

max insulin load

(g/kg LBM)

therapeutic ketosis 0.8 1.1
diabetes / nutritional ketosis 1.8 1.8
weight loss (insulin resistant) 1.8 2.9
weight loss (insulin sensitive) 1.8

Can run the numbers for me?

I realise all this data can be confusing if nutrition is not your hobby.

Over the last few months, I’ve been working with a very talented programmer, Alex Zotov, to develop some handy software to help people navigate all this information and put it into practice.

The first instalment of the Nutrient Optmiser is a free calculator that will help you identify the ideal macronutrient ranges to suit your goals as well as a shortlist of optimal foods and meals.  The table below shows how we can determine the optimal approach for you based on your metabolic health, waist to height ratio and goals.

We’d love you to check it out the Nutrient Optimiser.  We’d love to hear what you think and how we can refine it to suit your goals.

We hope it will be really helpful for a LOT of people on their journey towards health through optimal nutrition

analysis of what a nutritionist eats and hospital food

An article in Business Insider, A Nutritionist Shares Pictures of Everything She Eats in a Day, caught my eye recently.  I thought it would be interesting to run the numbers to see how the food diary logged by this nutritionist compared to the four hundred or so meals that I’ve analysed.

Check out the original article if you want to see the daily food log chronicled in photos by the popular and published “Registered Dietician”, who claims to specialise in diabetes and is “passionate about being a good role model.”[1]

The quantities and foods that I analysed in the recipe builder at SELFNutritionData are shown below.  Besides the fact that the only green things she ate during the day were M&M’s, the food log is not particularly divergent from mainstream dietary advice (i.e. no full-strength Coke or McDonald’s).  The nutritional analysis would be much worse if it was a diet full of junk food, which is pretty common for a lot of people these days in this fast-paced convenience-loving world.

image10

This dietician is a national media spokesperson for the Academy of Nutrition and Dietetics.  She has published books and written for several magazines.[2]  Like most nutritionists, she argues for less fat and more whole grains.[3]

image00

So, let’s see how her daily diet stacks up.  The analysis below shows that, when we compare this daily diet against mainstream dietary advice that nutritionists prescribe, it ticks the following boxes:

  1. avoids trans fats,
  2. is low in fat, and
  3. is low in cholesterol.

image05

However, even though the diet is fairly low in fat, it has 29g of saturated fat which is greater than the Heart Association’s recommendation for a maximum of 16g of saturated fat per day.[4]   Unfortunately, the recommended limit of saturated fat is actually quite hard to achieve without relying on low fat highly processed foods.

Ironically, due to the focus on avoiding fat and trying to incorporate more “heart healthy whole grains”, the food recommended by nutritionists ironically tends to be lacking in nutrients.  It makes no sense!

The registered nutritionist’s daily food log also contains more than 400 grams of carbohydrates which will be a massive challenge to someone who is insulin resistant, would likely generate insulin resistance and eventually diabetes in someone who isn’t there yet.

For comparison, check out the analysis shown below of one of my regular meals (stir-fry veggies with some butter and sardines) which has a much higher vitamin and mineral score (94 compared to 55) and better protein score (139 compared to 66).

image03

image18

When it comes to nutrient density and being diabetic friendly, this nutritionist’s daily food log ends up at the bottom of the pile of the four hundred meals that I’ve analysed!

It’s sad that this myopic one-size-fits-all dietary advice is forced on anyone who asks what they should be eating, or anyone whose food is influenced by government nutritional guidelines (e.g. hospitals, schools, jails, nursing homes etc).

Then we are told that dieticians are the only ones that are qualified to give dietary advice, even though the dietary advice that they give revolves around avoidance of saturated fat and more “heart healthy whole grains” and does not actually lead to high levels of micronutrition.

image12

Where it gets even sadder is that this sort of short sighted advice is also given to the people who are the most vulnerable.  The photo below is of Lucy Smith in hospital after being diagnosed with Type 1 Diabetes.  The diet given to her, as a newly diagnosed Type 1 Diabetic, is Weet-Bix, low fat milk, bananas, low fat toast, orange juice, and peaches.

image26

The analysis for Lucy’s hospital-provided breakfast is shown below.

image17

This single meal contains more than 200 grams of carbohydrates (82% of calories).  This breakfast would require a ton of insulin to be injected into her little body, and she would be on a blood glucose / insulin rollercoaster for days to come.

image16

When it comes to nutrient density, this meal has an even lower score than the day in the life of the nutritionist’s own diet discussed above!  Ironically, this hospital prescribed meal ranks at the very bottom of the list of four hundred meals when ranked to identify the best recipes for people with diabetes!

image14

Unfortunately, things don’t seem to have changed much from thirty years ago when my wife Monica was diagnosed with Type 1 Diabetes.  In hospital, after diagnosis, she was given so many carbs that she hid the food in pot plants in her hospital ward room because she just couldn’t eat anymore!  Twenty-five years later, she learned about the low carb dietary approach and she was finally able to reduce the high levels of insulin required to cover her food.

I’ve witnessed firsthand the massive improvements in quality of life (body composition, inflammation, energy levels, dental health etc) when someone comes off the blood glucose/insulin roller coaster!

Monica has been able to halve her daily insulin dose since no longer ascribing to the dietary advice she has been given by the dieticians and diabetes educators.  Her blood glucose levels are now better than ever and when she goes to the dentist, podiatrist and optometrist they tell her she’s doing great and they wouldn’t even know she’s diabetic.  And I get to have my wife around for an extra decade or two!

image04

By the way, Lucy is doing well now too.  Her parents are some of the most knowledgeable people I know when it comes to optimal foods for diabetics and monitoring blood glucose (as shown in this video from her father Paul).

My friend, Troy Stapleton, is another example of someone living with Type 1 Diabetes who has benefited immensely from a low carbohydrate dietary approach that aligns with his metabolic health.  His story and approach have been an inspiration to me.  You can also check out the Standing on the Shoulders of Giants article for a few more encouraging stories of people with Type 1 who got their life back after going against nutritionists orders.

As detailed in the article How to optimise your diet for your insulin resistance, if you have the luxury of being more metabolically healthy (i.e. not diabetic) you can focus on more nutrient dense foods or lower energy density if you’re looking to lose some weight.

image24

It amazes me that dieticians can be so militant and belligerent when they are largely passing on the recommendations of the US Department of AGRICULTURE (i.e. the USDA, also known as “Big Ag”), whose mission it is to promote the economic opportunity and production of AGRICULTURE[5] (i.e. grains and seed oils).  Talk about putting the fox in charge of the hen house!

image09

Speaking of conflicts of interest, it’s worth noting that major nutritionist organisations funding ‘partners’ are big food manufacturers.[6]  Does this influence the recommendations they give?  They claim not.

It’s hard to believe their published research or dietary recommendations could be impartial when so heavily sponsored by the food industry.

image06

Despite these conflicts of interest and a poor track record of success over the past four decades, I don’t think we should be gagging the Accredited Dietitians from publishing poor nutritional advice.  Everyone should be entitled to their freedom of speech and freedom to choose what they eat.

image23

What I do find ironic is that dieticians can bring spurious cases of malpractice against doctors to their governing bodies when they are acting in line with the latest research and their personal, professional and clinical observations (e.g. Tim Noakes in South Africa and Gary Fettke in Australia).  At the same time, the Registered Dieticians have no governing body to report to, only their board of directors[7] and their ‘partners’.

image13

image07

While they purport to be protecting the public interest, one could be excused for thinking that the dieticians’ associations are another marketing arm for big food companies and are protecting commercial interest rather than acting on behalf of public health.

16864248_10158266373295383_2174911756581917873_n

Is it just a coincidence that Nestle’s Milo, which is half sugar, is prescribed by hospital dieticians for pregnant and breastfeeding mothers with diabetes?

image30

Unfortunately, the situation isn’t that much different with the diabetes associations.[8]  Why would these institutions ever make recommendations to their members that reduced the amount of medications they needed or reduce the amount of processed food when their financial partners are pharmaceutical companies who manufacture insulin and drugs for diabetes?

image01

What would happen to this financial structure if a significant amount of people started eating whole unprocessed food without a bar code?  The share price of these massive medical and pharmaceutical companies would tank!

image22

After battling cancer himself and studying the role of nutrition in metabolic and mitochondrial disease in depth, Gary Fettke now spends his days as an orthopaedic surgeon amputating limbs mainly due to the complications of diabetes.

No, it’s not pretty, but unfortunately it’s very very real.

image19

Each year Gary volunteers as an orthopaedic surgeon in Vanuatu.[9] [10]  The contrast between the native people living in their natural environment, eating their native foods, and their relatives in town, eating processed foods, is stark.

I took this photo in a traditional village during our holiday in Vanuatu a couple of years ago.  These people eat lots of coconuts (which contains plenty of saturated fat, one of the remaining nutrients that Registered Dieticians still say we should avoid) and fish. These Vanuatu natives are some of the most beautiful, healthiest and happiest people I have ever seen!

image11

Unfortunately, in the capital Port Vila, it’s not so pretty.  The diabetes rates are the third highest in the world.  One in fifty Vanuatu natives have had an amputation!

It is such a big problem. Their diet has changed quite rapidly over the years, so instead of eating their island’s food, they now eat very large quantities of white rice and of course all the liquid sugar, like Coca-Cola and Fanta, and it’s literally killing them.[11]

After seeing the impact of diet, Gary has been outspoken in Australia, bringing attention to the quality of food that people are eating, especially in hospitals.[12]

image27

Gary and his Nutrition for Life Centre also worked with Chef Pete Evans on the “Saving Australia Diet” on national TV with great results achieved.[13]

image20

Then, in return for his efforts, Gary has been reported by the certified dieticians to the Australian Health Practitioner Regulation Agency; and he has been told he can no longer tell his patients to limit sugar even if they have just had their leg amputated due to the complications of diabetes.

Similarly, Tim Noakes has developed a massive following after realising that he needed to go against his own previous publications and advice when he found he was developing diabetes. The recipe book that he helped write, The Real Meal Revolution, is filled with nutrient dense low carb meals that help people with diabetes achieve normal blood glucose levels, has been massively popular.

image21

Despite his impressive track record of real results, which goes against the general trend of the explosion of diabetes and obesity in western society, Professor Noakes has been reported to the Health Professionals Council of South Africa (HPCSA) and charged with unprofessional conduct, after suggesting that a mother wean her baby on to whole foods rather than processed “baby food”.

image15

This has led to a long and expensive court case which really appears to be more about maintaining the status quo on the supermarket shelves rather than public health.[14]

I think most nutritionists believe that they are doing the right thing by advising their clients to prioritise the avoidance of fat, cholesterol and saturated fat, and eat “heart healthy whole grains”.  However, the foundation of this advice seems to be crumbling from underneath them with the most recent updates to the US Dietary Guidelines that now remove the upper limit on fat and removing cholesterol a nutrient of concern.[15] [16]

However, if we have to rely on Big Food to provide processed food products to achieve the reduced saturated fat aspirations of the dietary guidelines (and in so doing produce very otherwise nutrient poor foods), then perhaps we need to declare them broken and look for new ones?

Makes you wonder how we survived (let alone thrived) with the food that was available to us before the highly-processed foods and the low fat dietary guidelines that came to dominate our food choices in the 1970s.

Unfortunately though, fear of saturated fat still dominates the majority of mainstream dietary recommendations out there and leads to nonsensical food rankings that only suit the grain based food industry.[17] [18]

For example, the simplistic Australian Health Star Rating is based on the energy, saturated fat, sodium, sugar content along with the amount of fruits and vegetables in a product.[19]  This avoidance-based process gives little consideration for the amount of essential nutrients in a product, regardless of where they came from, and hence often returns nonsensical results.

It’s hard to tell whether the attacks on people like Fettke and Noakes are motivated by:

  1. Well-meaning nutritionists who earnestly believe that higher levels of fat and a lack of “heart healthy whole grains” is going to harm people,
  2. Nutritional institutions sensing that they are becoming irrelevant and making a last-ditch attack at their adversaries in an effort to hold onto their jobs,
  3. Processed food manufacturers (i.e. big food) using their “partner organisations” to attack these outspoken thought leaders so they can maintain their strangle hold on nutritional advice that suits them and sells more of their product (i.e. it’s not a conspiracy, it’s just business), or
  4. Some combination of each of these options.

To cut through the confusion and conflicts of interest, wouldn’t it be great if there was an unbiased quantitative way to judge whether a particular food or meal was optimal based its nutrient density?  Perhaps we could even tailor food choices based on blood glucose and metabolic health (i.e. using insulin load), or by manipulating energy density of someone who is insulin sensitive but just needs to lose weight.

If you’ve been following this blog, you may have seen the optimal food lists tailored to specific goals.  To this end, I have devised a system to identify foods for different goals and situations. The table below will help you choose your ideal dietary approach and optimal foods based on your blood glucose levels and waist to height ratio.

approach average glucose waist : height
(mg/dL) (mmol/L)
therapeutic ketosis > 140 > 7.8
diabetes and nutritional ketosis 108 to 140 6.0 to 7.8
weight loss (insulin resistant) 100 to 108 5.4 to 6.0 > 0.5
weight loss (insulin sensitive) < 97 < 5.4 > 0.5
nutrient dense maintenance < 97 < 5.4 < 0.5

The first step in improving your nutrition is to minimise processed food that is laced with sugar.  These food lists can help you further optimise your food choices to suit your goals whether they be blood glucose management, weight loss or just maintaining optimal health.

Once you normalise your blood glucose levels, you can then start to focus more on nutrient density.  If you still have weight to lose, then you can focus on foods with a lower energy density to force more energy to come from your body while still maximising nutrition.   You can also find the highest ranking of the four hundred meals that I have analysed listed here.

Several people recently have suggested that I turn the nutrient density ranking system into a mobile app for easy implementation of the ideas and theories outlined on the blog in the real world.

So, my current project is to develop a Nutrient Optimiser that would rank the foods you have eaten based on your current goals (e.g. therapeutic ketosis, diabetes management, weight loss or maximising nutrient density) and recommend new foods to try.  The Nutrient Optimiser would progressively retrain your eating patterns towards ideal by helping you to maximise the more optimal foods, and progressively eliminate the foods that don’t align with your goals.   Whether you are trying to eat less Maccas, or you are practising Calorie Restriction with Optimal Nutrition (CRON) and trying to live to 120, the Nutrient Optimiser would push you forward to truly optimise your nutrition.

The idea is not to simply create another calorie counting app.  There are plenty of those out there already.  Rather, the Nutrient Optimiser will help you to maximise nutrient density as much as you can while catering to your other goals.

Rather than being centred on outdated “science” and avoiding boogeymen such as cholesterol, fat and saturated fat, or serving the interest of “financial partners” (e.g. BigFood and BigPharma), the Nutrient Optimiser uses a quantitative algorithm that will help you maximise the nutritional value of the food you eat.

The Nutrient Optimiser, based on the foods logged in the past few weeks, helps you to identify foods that would provide the nutrients that you haven’t been getting as much of.  Rather than just tracking calories, the app will continually adapt to what you eat, ensure that you are getting a broad range of foods that contain the nutrients you need, and ensure you don’t get stuck in a nutritional rut.

For people just starting out, it will help them gently move forward, without the judgement of someone looking over their shoulder.  It will suggest foods they should buy more of, new foods to try, and maybe which foods they should bin and never buy again.

For people who are truly wanting optimal nutrition, it will hopefully be the ultimate tool to continue to refine their food choices to maximise nutrient density while optimising blood glucose, insulin and body fat levels.

As you continue to log your weight, blood glucose levels and whatever other metrics you want to track, the app will progressively prompt you to “level up” to a more optimal nutritional approach.  Then, with your nutritional deficiencies filled, the cravings will dissipate and you will naturally be satisfied with less food.[20] [21]

If something like this is of interest to you and you want to be an early adopter or just check it out the nutritional analysis of other people food logs that have been done so far then then take a look at the Nutrient Optimiser Facebook page and to stay posted as things develop.

nutrient dense foods for weight loss and insulin resistance

I found a number of people that were using 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 are fairly low in dietary fat to allow for to come from 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 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.

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 shows 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 (MCA) that combines all these factors.

The chart below shows the amount of each nutrient provided by the more balanced approach compared to the 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.
