which nutrients is YOUR diet missing?  

I recently took a look at which nutrients might be missing from various popular dietary approaches in preparation for a recent on nutrient density.  At a population level, the chart below shows the proportion of the US population that are deficient in various micronutrients.  Many people are not getting enough vitamin D, vitamin E, magnesium, calcium, etc.

While your body hasn’t read the World Health Organisation’s reports on the Daily Recommended Intake of the various essential nutrients,[1] it’s likely that your appetite will drive you to seek out the nutrients that are lacking.  If we are deficient in something that is required the body kicks in “nutrient hunger” and cravings that will make sure it gets what it needs.[2] [3] [4]

If you work hard to restrict your food intake to a certain dietary approach, but the body doesn’t receive the nutrients it needs, it may slow down and not function at full capacity.   By contrast, adequate nutrition, without too much energy, slows many of the modern diseases of aging such as diabetes, Alzheimer’s and cancer and improves your chance of living healthfully to a ripe old age.[5]

USDA foods database

The chart below shows the nutrients that are both easiest and hardest to obtain from the eight thousand foods in the USDA foods database.  At the bottom of this plot we have iron, various amino acids, and vitamin C, all of which are easy to obtain in adequate quantities.

However, at the top of the chart, we can see that it is much harder to obtain adequate quantities of six essential nutrients (omega 3 fatty acids, vitamin D, choline, vitamin E, and potassium).  We would obtain sufficient quantities of all the other essential nutrients if we ate just a little of each of the foods in the USDA food database.

If we want to maximise nutrient density, it makes sense to prioritise foods that contain more of the harder-to-obtain nutrients.  The chart below shows the nutrients for the top 10% of the 8000 foods in the USDA database (blue bars) when we prioritise for those.  Not only do we get an increase in the more difficult to obtain nutrients, we also get a massive boost in all nutrients.  Rather than being inadequate in six nutrients, we are now lacking only one (alpha-Linolenic acid, an Omega 3 fatty acid).

Limiting our food selection to the most nutrient dense foods makes it easier for us to consume the required nutrients without excessive energy, which is ideal if we are trying to lose fat or reduce calorie intake to slow the diseases of ageing.[6] [7]  Nutrient density becomes even more important if you’re fasting or restricting calories to achieve long term weight loss.

Optimising nutrient density

If you’re reading this, then you’re likely aware that there is a wide variety of dietary approaches that people follow to optimise their health depending on their preferences and beliefs.

I’ve tried to turn many of these beliefs about nutrition into a quantitative algorithm that we can use to evaluate and compare these approaches, and make sure we’re getting the outcome we want (e.g. low insulin, blood glucose control, nutrient density, or low/high energy density).

After testing a number of options, the three quantitative parameters that I have found the three parameters that are most useful are:

  • insulin load,
  • nutrient density, and
  • energy density.

My aim in this post is to show how considering nutrient density can improve various dietary approaches, from therapeutic ketogenic, vegan, paleo, and low fat.   This post highlights which nutrients you will most likely be lacking with each of the different nutritional approaches, which foods you can use to fill these nutritional gaps, and perhaps which supplements you may need if you are still looking for some added nutritional insurance.

There’s been a lot of talk lately by Taubes[8] and Lustig[9] about how bad sugar and fructose are, but I think these nutritive sweeteners are just extreme examples of nutrient poor foods that are highly insulinogenic and energy dense.  At the other end of the spectrum, we have foods like liver, broccoli, and spinach.  Everything else is somewhere in the middle and will support or work against your goals, whatever they may be, to different degrees.

My aim here is to help you see where each of these foods sits on that continuum and use this information to help you refine your food choices to reach your personal goals.

Therapeutic ketogenic diet

Let’s start with the therapeutic ketogenic dietary approach.   I have previously noted that a number of the issues and concerns with the ketogenic diet seem to relate to being able to obtain essential nutrients rather than consuming excessive levels of fat.[10] [11] [12]  On one hand, I’m excited that the concepts of insulin load and percentage of insulinogenic calories have been helpful for people with chronic conditions such as epilepsy, cancer, dementia, Alzheimer’s etc.  However, I think there is a risk their ultra-high fat diet will not contain the nutrients which are critically important for mitochondrial function and energy production.

The chart below shows the vitamins and minerals provided by a therapeutic ketogenic dietary approach if we simply prioritise for low insulin load (red bars)[13] in comparison to the average of all foods in the USDA database (orange bars).  If you don’t pay attention to nutrient density a therapeutic ketogenic diet can provide lower levels of nutrition.

As shown in the chart below if we ate a little of all the foods in the USDA database, we would be deficient in six essential nutrients, whereas if we follow a therapeutic ketogenic diet, we will likely be lacking in ten essential nutrients.

The chart below shows the effect of how thinking in terms of nutrient density can improve the therapeutic ketogenic dietary approach (blue bars) compared to prioritising for insulin load only (red bars).  All nutrients are boosted, particularly the harder to obtain ones.

While lots of people find that higher fat whole foods are hard to overeat, there are still some hyper palatable high fat foods that go down easily.  We talk about eating “fat to satiety”, but what happens when nutrient hunger kicks in and your body is craving more potassium, magnesium, calcium, or one of the other nutrients that are harder to obtain in a very high fat dietary approach?  If you keep on consuming large amounts of processed fats that don’t contain the nutrients you require, your appetite may not automatically turn off before you’ve consumed a lot of excess energy!

Low carb

The chart below shows the boost in nutrients when we consider nutrient density combined with a low carbohydrate approach.  It appears that, based on this analysis, that without a focus on nutrient density, a low carbohydrate diet is likely to be deficient in folate, vitamin D, choline, potassium, magnesium, pantothenic acid, calcium, vitamin E and manganese.  With a focus on nutrient dense foods, a low carb diet provides adequate amounts of the majority of nutrients.

Weight loss (insulin sensitive)

The weight loss approach is intended for people who are insulin sensitive but still have excess body fat to lose.  Foods with a lower energy density (e.g. spinach, broccoli cucumber, celery, lettuce etc) typically are harder to overeat because they are bulky.

This approach doesn’t pay any attention to insulin load because it is assumed that people using this approach are not insulin resistant and are able to maintain good blood glucose levels.  Practically, it’s also difficult to achieve a really high insulin load with these foods because they do not contain a large amount of processed carbs and are hard to overeat.

Without consideration of nutrient density, the essential fatty acids tend to be low along with vitamin B-12, choline, and tyrosine.  However, once we factor in nutrient density all these nutrients dramatically improve.

This approach may not be viable for long term maintenance due to the extremely low energy density which would make it hard to get in enough energy.  However, in the short term, it may be appropriate for a period of substantial energy restriction, and will provide maximum nutrition with a minimum amount of energy.

Zero carb

Getting adequate protein on a zero-carb approach is not a problem.  However, unless there is a major focus on organ meats, there are a large number of vitamins and minerals, such as   vitamin K, manganese, vitamin C, vitamin E, vitamin D, potassium, magnesium and calcium that may be worth supplementing.


At the other extreme, the chart shows the nutritional analysis of the vegan diet.  The main deficiencies in a vegan approach are omega 3s and vitamin B-12, which are hard to obtain without animal products.  It may be prudent for vegans to consider fish oil supplementation and B-12 injections, or alternatively adding some seafood occasionally.

While it appears possible to obtain the recommended levels of protein, it’s hard to get very high levels of it.    If you are insulin resistant, the fat levels can be increased using added coconut products and nuts.

Higher insulin load foods for bulking

The bulking approach is designed for people who are looking to gain strength and size by combining nutrient density with more calories and insulin load.  Without consideration of nutrient density, a high insulin load means very low nutrient density foods.  However, once we factor in nutrient density, we get a range of highly nutritious foods that may be helpful if you want to gain size and strength, while still maximising health and nutrition.


The chart below shows the nutrients provided by the Paleo approach (i.e. no processed foods, dairy or grains) both with and without consideration of nutrient density.  While ‘going Paleo’ eliminates many of the nutrient-poor processed food, it appears to be beneficial to also consider nutrient density as well in addition.

What does this all mean?

So, how do we decide which approach is best?  Unfortunately, it’s not straightforward so I’ll look at this a number of ways.

What we ideally want is to identify the foods that will provide us with high amounts of all of the nutrients.   The blue bars in the chart below represents the average of the % daily recommended intake of all the nutrients in the various approaches evaluated above, without considering nutrient density.  The orange bars represent the average minus 0.5 x the standard deviation which is a measure of reliability.  The higher the reliability the more consistent and high are the nutrients over all.

This chart shows that, in comparison to the other approaches, Paleo foods have a high and consistent level of nutrients; while the vegan and low energy density weight loss foods have high levels of some individual nutrients, but low levels of some others.  Without consideration of nutrient density, the high insulin, low carb and zero carb approaches are a bit lacking in nutrients.

Things become a little more interesting once we factor in nutrient density.  The vegan, therapeutic keto, low carb and zero carb approaches do poorly against the paleo, higher insulin load, most nutrient dense of all foods, and the lower energy density weight loss foods.

Many people will benefit on a high fat therapeutic ketogenic dietary approach, at least until their blood glucose and insulin levels normalise.  However, in time, it may be beneficial to transition to more nutrient dense foods to continue their journey towards optimal health.

As detailed in the ‘how to optimise your diet for insulin resistance’ article, I think you should eat the most nutrient dense foods your pancreas can keep up with while maintaining good blood glucose levels.  In time, someone who is highly insulin resistant may be able to progress to a more nutrient dense and more moderate fat approach if your ultimate goal is to normalise blood glucose levels and lose weight.

Food lists

If you identify with any of these goals, you may be interested in following these food lists.   If blood glucose levels are sky high or you are managing a chronic condition such as epilepsy, cancer, Alzheimer’s or dementia, you may benefit from a higher fat therapeutic keto dietary approach, for a period.  As your glucose levels come under control, you can transition to more nutrient dense foods that will also help you to achieve your weight goals.

Getting even more personal

As you can see, nutrients are provided at different levels depending on the approach.  However, most people don’t follow any dietary approach strictly, so the nutrients in your diet will be different depending on your personal habits and preferences.

Rather than trying to pick up someone else’s nutrition plan, or live by a strict list, I think it’s better to refine your current habits, emphasising the good foods, minimising the bad, and progressively trying new foods that may be beneficial.

To this end, I’ve been developing a Nutrient Optimizer algorithm that can help you refine your food choices to suit your goals.  By identifying the foods you are currently eating that align most with your current goals, which ones don’t, and which new foods perhaps you should consider.

Most current nutritional advice is driven by the avoidance of fat, particularly saturated fat, and therefore ends up being next to useless.  Calorie counting apps like MyFitnessPal does nothing but count calories, which is also of limited use.  Cron-o-meter tracks your micronutrients and can recommend foods to boost a single nutrient.  However, there doesn’t seem to be anything available that will tell you which foods will help you actually correct multiple deficiencies and  achieve a diet that is truly balanced in micronutrients.

The Nutrient Optimiser also allows you to tailor the approach to your goals, such as:  therapeutic ketosis, diabetes management, weight loss or just nutrient dense maintenance.  Food preferences like vegan, pescetarian, autoimmune, or paleo can be factored in to the recommended food lists.

At the moment, the process involves manually exporting food intake data from Cron-o-meter, then analysing it in a spreadsheet to manually generate a personalised report.  I am eager to do this as a proof-of-concept for a range of people with various goals (particularly therapeutic ketosis, vegetarian, zero carb, fruitarian) to demonstrate how it works.  So, if you’re happy to have your report shared publicly, and have a couple of weeks of Cron-o-meter data, feel free to send it to me and  have your data analysed.

In time, the plan is to automate the process via an online interface and then ideally an independent mobile app.    To keep up-to-date with progress, watch this space and check out the various analysed examples on the Marty Kendall’s Nutrient Optimiser Facebook page.

Epilogue…  limitations

For completeness, I thought it would be worth mentioning a few limitations relating to calculating nutrient density…

  1. Measuring foods in terms of calories has its own limitations as different macronutrients provide different amounts of energy (ATP) in different people. Some smart friends of mine are working on calculating ATP yield for different foods based on their macronutrient content.  I’ll happily update this analysis in terms of nutrients per ATP as soon as that data is available.  Initial indications are that people who are fat-adapted are able to use fat more efficiently (i.e. less entropy/losses in metabolism) and hence require less calories to yield the same amount of energy in the body (i.e. ATP).  Hence, it appears that it is even more important for someone following a low carb or ketogenic approach to maximise nutrient density in terms of nutrients per calorie.
  2. The official dietary reference values are based on limited research.[14] Typically, they relate to the minimum amount of a nutrient to avoid disease rather than the amount required for optimal function.  They may also vary by person (e.g. someone who is more active may need more protein) and by their diet type (e.g. someone who is on a low carb diet may need less vitamin C to process the limited amount of glucose).  Hence, I think the DRI values should be seen as a minimum.  Ideally, we want to get more than the minimum while not having to ingest too much energy.  I also don’t think nutrients are meant to come as individual vitamins and minerals in a bottle.  The nutrients required to metabolise a certain food typically come packaged in whole foods, and often work synergistically.  Taking supplements or fortifying foods will always be inferior to obtaining nutrients from whole foods.
  3. Species-specific bioavailability and anti-nutrients are contentious topics. Zero carbers will tell you that nutrients in animal based foods are more bioavailable than plant based foods, while the vegans will tell you the opposite.  To date, I haven’t been able to find useful data that would enable me to quantitatively refine the nutrient data in the USDA database regarding bioavailability.  All we currently have is a measure of the nutrients contained in the food– rather than the nutrients that make it into your body after digestion.  Again, if this data ever comes to hand, I’ll eagerly update the analysis.

Overall, I don’t think these limitations make a difference in the outcomes of the analysis.  This is not an exact science and the body doesn’t operation like a rigid machine.  Calculation of nutrient density is just a way to identify the foods that contain the most raw materials with the least amount of calories that your body can work with.














[13] In terms of macronutrients this high fat dietary approach comes out at 80% fat, 15% protein, 2% fibre and 3% net carbs.


comparison of nutrients by food group

There are lots of claims about different dietary approaches.

  • Fruitarians advocate living on 30 bananas a day say you don’t need much else for health and athletic performance.[1]
  • Vegans say that in addition to high levels of vitamins and minerals, you can get all the protein and essential fatty acids you need from plant based foods.[2]
  • Zero Carbers who look like they’re doing great on purely animal foods and no plants and say they don’t need fibre and perhaps vitamins and minerals.[3]
  • Ketonians believe that you can’t go wrong with fat.[4]
  • Meanwhile the registered dieticians tell us that we shouldn’t eliminate whole food groups (like grains) or risk missing out on essential nutrients.[5]

As detailed in the Building a Better Nutrient Density Index article, we can quantitatively rank individual foods based on their nutrient density.  Eating nutrient dense foods will enable us to maximise satiety and avoid malnutrition and reduce the energy intake while avoiding malnutrition.

The Most Nutrient Dense Superfoods  article lists a wide range of whole foods from various food groups.   But could you thrive on a single food group?  And if you had to live on a single food food group, is there one that would be better than the others?

This article compares the the nutrients provided by the following food groups:

  • vegetables
  • fruits
  • cereals and grains
  • legumes
  • nuts and seeds
  • grains and cereals
  • eggs
  • dairy
  • animal products
  • ketogenic[6]
  • must nutrient dense

All of the charts below show the vitamins, mineral, amino acids and essential fatty acids on the same scale for comparison.   I have also included a selection of the most nutrient foods as an example.

I’ve listed some pros and cons that came to mind for each category.  I’m sure you could come up with some of your own.




  • It’s hard to eat too many vegetables as they typically have a low energy density and high nutrient density which will lead to increased satiety (adequate nutrients) and satiation (feeling full).
  • As well as vitamins and minerals, it appears that you could obtain adequate (but not excessive) protein from nutrient dense vegetables (i.e. you could get more than 100% of the DRI for the amino acids from vegetables only).
  • Vegans who consume exclusively plant foods tend to have a lower BMI and less diabetes. This makes sense as limiting yourself exclusively to low energy density plant based foods would help to prevent you overeating.


  • A diet comprising of only vegetables may be lower in Vitamins E, D, choline, and pantothenic acid.
  • Vitamin V-12 is very low in plant based foods.  One of the common concerns when it comes to plant based diets is a lack of vitamin B-12 and vegans often require B-12 injections.[7]
  • There are negligible quantities for the essential fatty acids EPA and DHA in vegetables. If you were to eat only plant based foods it might be beneficial to supplement with essential fatty acids.[8]
  • Vegetables are not subsidised the way that grain based foods often are. They do not store and transport as well as more processed foods and hence can be more expensive.
  • Vegetables can require more preparation and cooking time than processed pre-packaged foods.

  • Fruit provides solid levels of vitamins and minerals and has a lower energy density compared to grain based foods.
  • Fruits are can be more transportable compared to vegetables (e.g. easier to put in school lunches).


  • Fruit tends to have the same nutritional gaps as vegetables (i.e. vitamin E, D, pantothenic acid, choline and essential fatty acids).
  • Some fruits have a higher energy density and amount of non-fibre carbohydrates compared to vegetables. This may be an issue if you are watching your blood glucose levels or your weight. Many fruits have a very high proportion of insulinogenic calories so may not be ideal for someone who is insulin resistant as it will raise their blood glucose levels.

grains and cereals



  • Grains are cheap compared to fruit and vegetables, largely due to production subsidies.[9]
  • Grain based foods can be processed (to remove the fibre and water) so they can be easily transported and stored for longer periods.
  • Grains provide some fibre, but less than vegetables.
  • Grains provide a provide a wide range of nutrients, but at much lower levels than the other food groups.


  • The highest nutrient density grain based foods are typically unprocessed and rarely consumed.
  • The nutrient density of most breads and cereals are very poor, particularly after processing.
  • Grains have a high energy density, a high proportion of insulinogenic calories and a high amount of non-fibre carbohydrates. image04

  • Legumes provide a range of nutrients at a lower cost compared to vegetables.
  • The energy density of beans and legumes is moderate so they can provide more fuel if you can’t fit in any more veggies.
  • Legumes provide a solid level of protein, particularly for those not wanting to consume animal based foods.


  • The nutrient density of legumes is low compared to other sources such as vegetables.
  • Legumes have higher levels of non-fibre carbohydrates and a higher proportion of insulinogenic calories which may be problematic if you are watching your blood glucose levels.
  • Some people can’t tolerate high levels of the lectin proteins in legumes.[10] [11]

nuts and seeds



  • Nuts are higher in what is typically considered to be ‘good fats’ (i.e. MUFA and PUFA).
  • Being higher in fat they are a good way for people with diabetes to get their calories without raising their blood glucose levels.


  • Nuts and seeds provide a good range of vitamins and minerals but at lower levels per calorie than some of the other groups due to the higher energy density.
  • Nuts are calorie dense which may make weight loss more challenging.
  • Nuts have a relatively low nutrient density due to their high energy density.

eggs and dairy



  • Eggs have a solid protein profile, some EPA and DHA and a reasonable amount of vitamins and minerals.
  • Eggs and cheeses are typically lower in carbohydrates which is useful for people trying to normalise their blood glucose levels.
  • Dairy foods like cheese and cream are lower in non-fibre carbohydrates and have a low proportion of insulinogenic calories meaning that they won’t significantly raise your blood glucose levels.


  • The energy density of cheese and some other dairy products is higher which makes it possible to overconsume. Lots of people do better with weight loss when they limit milk and cheese.
  • While the latest US dietary guidelines committee has stated that saturated fat is no longer a nutrient of concern,[12] many people are still concerned about their levels of saturated fat.
  • Milk, a commonly consumed dairy product, is not particularly nutrient dense and contains lactose which will raise blood glucose. Though full fat milk is better than low fat.
  • Many people find that they are allergic to eggs[13] or dairy[14].

  • Seafood contains essential fatty acids EPA and DHA that are hard to obtain in the rest of the food system.
  • Seafood products have very high levels of protein and substantial levels of many vitamins and minerals.
  • Seafood has a low to moderate calorie density (i.e. lower than high fat cheese cheese but higher than vegetables).
  • Because seafood is so rich in essential fatty acids and amino acids we don’t actually need that much to cover our minimum requirements.


  • Fish can be more expensive than other foods.
  • Many people are concerned about heavy metal toxicity and sustainability issues surrounding seafood.[15]

animal products



  • Animal products have an excellent amino acid profile as well as significant amounts of other vitamins and minerals.


  • Animal products are lacking in a number of vitamins and minerals such as manganese, vitamin E, vitamin D, folate and vitamin K as well as essential fatty acids EPA and DHA.
  • Similar to fish, many people have concerns in the areas of sustainability and environmental impact.

most ketogenic

The ‘most ketogenic foods’ are the 500 foods with the lowest percentage of insulinogenic calories of the 7000 foods in the USDA foods database.



  • If someone is insulin resistant, replacing processed non-fibre carbohydrates with fat will help to reduce insulin and blood glucose levels.
  • The ketogenic approach has relatively high levels of essential fatty acids. While the nutritional value of fat is a contentious issue, many fatty acids have substantial positive nutritional value.[16]
  • People who are insulin resistant will benefit by reducing the insulin load of their diet.


  • The nutrient density of a therapeutic ketogenic approach is relatively poor. Someone looking to manage insulin resistance and diabetes should maximise nutrient density as much as possible while still maintaining excellent blood glucose levels.
  • A high fat / low insulin load diet is typically satiating,[17] however it is possible to overdo energy dense foods to the point that you won’t lose weight.

comparison of the nutrient density by food groups

The chart below the average nutrient density of all the different food groups in terms of amount of nutrients provided versus the daily recommended intake.  If we just look in terms of average nutrient density (blue bars), fish does pretty well, followed by animal products and then vegetables.

However, what we really want is high levels of nutrient density across the board, not just a large amount of a few nutrients.  For example, fish and animal products have very high levels of protein but lower levels of vitamins and minerals.  By comparison, vegetables have higher levels of vitamins and minerals and do OK when it comes to amino acids.  What we want is for the quantity of nutrients to be high and the variability across the nutrients to be low.

The orange bars show the average nutrient density minus 0.8 times the standard deviation in the nutrient density.  When we look at it this way the vegetables do the best of the food groups because they provide a good range of vitamins, minerals and proteins.


However, in the end though it’s the most nutrient dense foods that win out because they provide high levels of a broad selection of all the nutrients.  So, rather than focusing on a particular food group, if you’re interested in maximising nutrient density, the optimal approach appears to be to focus on the most nutrient dense foods across all of the food groups.

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.

Dr Rhonda Patrick’s Ultimate Micronutrient Smoothie versus Zero Carb Gregg

I recently ran the numbers on Dr Rhonda Patrick’s Ultimate Micronutrient Smoothie that Rhonda and her husband have for breakfast every day.   

I enjoy Rhonda’s podcasts as well as her mentor Bruce Ames’ pioneering work in the area of nutrient density.   I was pretty hopeful that Rhonda’s daily breakfast would knock it out of the park.  

So far I’ve run 235 meals though a system that ranks meals in terms of nutrient density, protein score, energy density and insulin load.  A score of 100 in the Nutrition Data analysis means that you would achieve all your daily requirements with 1000 calories (notwithstanding the limitations of bio-availability, anti-nutrients, fat soluble vitamins etc).  

In terms of vitamins and minerals it did pretty well ranking at number 40 of 235 meals analysed to date. Liberal doses of kale and spinach always tend to boost the vitamin and mineral score.  These green leafies contain heaps of vitamins A, C, K, B and folate as well as solid amounts of the minerals magnesium, phosphorus, copper and manganese.

rhonda's smoothie

If you’re interested, the meal that ranks the highest in terms of vitamins and minerals score is Terry Wahls’ lamb skillet meal (shown below).  While you might think that a vegetarian meal might win in the vitamins and minerals category, Dr Wahls’ combination of broccoli, garlic, and spinach along with lamb and coconut oil actually does even better with a score of 94 compared to the green smoothie which has a score of 75.   


The good thing about blending everything into a smoothie is that you will be able to get more green leafy veggies down the hatch.  The downside is that you might lose some of the beneficial effect of the fibre.  The same thing can be said for cooking.  

In terms of amino acids though, the  smoothie was a bit disappointing coming in at 196 of 235. Some people will argue that low protein isn’t a big deal and that 9% protein is adequate.  Others think you would need more protein. 

The answer for you will depend on your activity levels and whether you want to be big and strong or whether you have some muscle mass that you don’t mind donating in the name of nutrition and weight loss.  


The 57g of fibre was pretty good from all those leafy greens, ranking at 75 of 235 in terms of fibre.  Energy density was also pretty good, ranking at 100 of 235, which means that the smoothie will be quite filling and not easy to binge on.   

The insulin load was a bit disappointing.  At 50% carbs the smoothie mixture came in just above the porridge with blueberries in terms of insulin load.  This may not be a problem if you’re insulin sensitive, but people struggling with diabetes might suffer with the apple and banana which don’t add much in terms of nutrient density (other than sweetness which would add to the palatability of the smoothie).  

minus the apple and banana

So for interest I dropped out the apple and banana and the ranking improved in terms of vitamins and minerals, though it didn’t change the protein score.   The insulin load ranking improved marginally from 228 to 206.  


Overall, this may not be a bad option for breakfast if you’re not diabetic and get some additional protein later in the day.  Living on Rhonda’s smoothe may also not be optimal if you’re looking to maintain / build lean muscle.

and now for something completely different… zero carb Gregg

After releasing the ketogenic fibre article in October 2015 I got into an interesting discussion with Gregg about zero carb and ended up running the numbers on his typical daily diet which largely consists of meat, butter and cream.

As shown below, the protein score of Gregg’s daily diet is solid, though the vitamin and mineral scores are not so great (214 of 235).   The insulin load of Gregg’s typical daily diet is pretty good coming in at #50. 


[note: Just for interest Bulletproof Coffee comes in at #1 on the insulin load ranking but last in terms of vitamins and minerals and second last on the protein.]

Many people find that they do really well with a zero carb approach, particularly if they have major digestive issues.  People who are fans of zero carb often speak highly of Fibre Menace by Kanstantin Monastrysky.  It seems that people with major digestive issues can get relief from their inability to digest FODMAPS using a zero carb approach.  

Overall I’m a fan of fibre and wonder if people might benefit from the slow reintroduction of some fibre for the sake of their gut microbiome and promoting well rounded nutrition once their gut has settled.  

It’s also it’s interesting protein makes up only 22% of Gregg’s zero carb diet because of the solid amount of fat from the beef and the added fat from the butter and cream.  This sort of approach might work well for people who are insulin resistant.  

can you get enough vitamins and minerals from a zero carb diet?

Lots of people who use a zero carb approach say that they can get all the vitamins and minerals they could even need from animal products, so I threw in some sardines and liver to see how high we could get the vitamins and minerals score without any green stuff.  

As you can see below, the protein score improves with the fish and liver (I’m not vouching for the palatability though).  This meal now ranks at #1 for protein score with a massive score of 159 on the amino acid score!  The vitamins and minerals take a significant jump to #142 of 235 with the addition of the sardines and liver.

So it seems that there are some benefits of a zero carb dietary approach, but perhaps some limitations when it comes to the vitamin and mineral side of the equation.  


joining forces

But then I thought, “what if Rhonda made Gregg breakfast and Gregg made dinner for Rhonda?”

As you can see from the analysis below, combining the green smoothie (without the fruit) with the zero carb approach (with sardines and liver) went really well in both the vitamins and minerals ranking (#20) and amino acid score (#41).  Not a bad balance overall!  

On the weight loss ranking this meal combination would come in at #26 of 235, on the athlete ranking it comes in at #10, on the diabetes and nutritional ketosis ranking it comes in at #23, and for therapeutic ketosis ranking it comes in at #67.  

Overall, not a bad balance of the extremes?


what to make of all this?

Lots of people get hung up on a particular magic nutrient and spend a lot of money to supplement just one missing ingredient.  However perhaps it would be optimal (and cheaper?) to get a high quantity of a broad range of nutrients from whole food sources.

Real foods that were recently alive are going to be a better bet than relying on supplements.  

Should you eat more plant foods, more protein, or more fat?  The answer will depend on your situation, your goals and your preferences.  As always, optimal lies somewhere between the extremes.  


enter…  Nutrient Optimiser

More recently, I have been working on a tool to help people optimise their micronutrient balance while also being tailored to their metabolic health and goals.

The Nutrient Optimiser reviews your food log diet and helps you to normalise your blood glucose and insulin levels by gradually retraining your eating habits by eliminating foods that boost your insulin level and blood glucose levels.

Once your glucose levels are normalised, the Nutrient Optimiser focuses on refining your micronutrient fingerprint to identify foods that will fill in your micronutrient deficiencies with real food.


If you still have weight to lose, the Nutrient Optimiser will focus on the energy density of your diet until you have achieved your desired level of weight loss.  Alternatively, the Nutrient Optimiser can help you if you were looking to increase your insulin levels for bulking or identify higher energy density foods for athletes.

It’s early days for the Nutrient Optimiser, but the initial results are very promising!
