Dear Mark: Metabolic Typing

By Mark Sisson
93 Comments

Dear Mark,

I’d love to see your take on the validity of the metabolic type diet. I have found that a primal-style eating plan similar to yours works wonders for me, but I have seen some people comment that they maintain lean bodies with a very different approach than you. One commenter even stated that he gains weight when he increased fat calories. It seems like people can react differently to certain foods.

Metabolic typing periodically gets a boost in press every once in a while. The premise of typing suggests that people have distinctive metabolisms that are best served by a corresponding nutrition profile. Presumably, these metabolic distinctions are genetic differences based on your ancestors’ geographic origin. For example, if your ancestors are from the South Pacific islands, your nutritional needs differ significantly from those of the Lapps in Scandinavia, etc.

(Metabolic typing is different from the “blood type diet” you might occasionally hear about, but some people try to emphasize what they see as the overlap between the two “theories.”)

Traditional metabolic typing uses three categories: protein type, carbo type, and mixed type. As you can probably guess, “protein types” are supposed to eat protein- (and fat-) rich diets. “Carb types,” according to this theory, do well with a high carb, low protein and fat diet. “Mixed types” are supposed to thrive on equal parts proteins, fats and carbs.

And it gets more intricate/convoluted from there. Your “type” theoretically shows if your sympathetic or parasympathetic nervous system is “dominant” in your personality and physiology. Some of the tests and descriptions go into detail about everything from “fast/slow oxidation” to endocrine gland dominance. Supposedly, if you eat “according to your type,” you will finally be able to maintain good health and a normal weight. You can get long, exhaustive testing and reports that gives you this information, usually for a certain price. (Imagine that.)

What’s my estimation of this theory? Hooey, humbug, nonsense. But let me tell you why.

In last week’s post Did Grok Really Eat That Much Meat?, we cited research highlighting the substantial role that animal sources (fish/meat, fat/protein) played (and still play) in traditional hunter-gatherer diets. The study established a range of animal source intake between 45-65% of total energy intake. While the 20% difference isn’t exactly trivial, it’s still pretty minor in the grand picture.

It’s true people sometimes respond slightly differently to particular foods (like raw nuts, for example), and occasionally we find tolerance related patterns within particular ethnicities. An example of this pattern would be the fact that most of the world has a higher level of lactose intolerance than certain European ethnic groups. Nonetheless, we’re still talking about pretty targeted food sources. Despite these relatively minor patterns and individual issues, the fact is we all share the same biochemistry. (As in, our bodies all pump out insulin in response to carb intake….) Some people might be more sensitive to lectins, but lectins are still processed by those people’s bodies the same way they are by everyone else’s systems. The same goes for other food sensitivities, even those that may show a population-based pattern.

Let me say it this way. Having particular sensitivities to foods or preferences for foods doesn’t equate with the need for a different macronutrient composition in your diet. One size fits all may not be exactly right – there is a range. But that range is much narrower than the metabolic typing theorists want to suggest… We each might prefer to get our protein through a unique combination of meats and other foods (nuts, etc.), but we share the need for significant protein intake.

There are, indeed, other individual factors that influence our nutritional needs and sensitivities, but I’d argue that these don’t have anything to do with where Great-, Great-, Great-, Great- (and so on) Grandpa came from. They have to do with age, gender, personal medical condition and hormone balance, exposure to toxins and allergens, etc.

And then there’s the part about weight maintenance/loss. Sure, some people out there have a harder time gaining muscle mass despite their best efforts. Some people, while they’re perfectly healthy, have a harder time maintaining a “thin” physique. But a type report isn’t going to offer any new answers. Controlling your hormonal balance by minimizing carbs is the key. (And as for those people who eat carbs but look thin, they’re still throwing their body into hormonal havoc, despite their denial. Thin doesn’t necessarily equal health.)

Once again, within our individual ranges, we can all expect to achieve a healthy body by practicing what we know to be true over millions of years. At the end of the day, there’s undeniably a surprising consistency in our nutritional needs. A hunter-gatherer style diet (cornerstone of the Primal Blueprint) has held up time and time again as offering the best promise for true health and best protection against chronic disease.

Thanks, as always, for your questions and comments, and keep ‘em coming!

Thank you for adressing this Mark! I actually found the Primal Lifestyle partially because of internet researching after reading “Eat Right for your Blood Type”. I have often thought about asking you for your thoughts on this concept. I know that this post is about metabolic diets and not bloodtype diets, but I think that almost every one of your points could be applied to either so i will count this as an answer to my question too! My mother, who is a big proponent of the “eat right for your blood type” methhidoly constantly gives me a hard time… Read more »

the response to metabolic typing is extremely insubstantial and poorly responded to. If you know anything about metabolic typing it would make sense to point out all flaws and compare them with what you think is better than the thing you dislike about it, rather to sugar coating your paragraphs with insubstantial comments..keep your mind open listeners.. I’d like to see a more substantial response.

Yes, MT is a bunch of baloney. The similarities between one human and the next far outweigh any minor differences. And the methods they use to determine your “type” are pure nonsense. Great post, Mark.

Interesting perspective, as always, thanks! I only know, for sure, what works for myself and have often wondered how much truth was found by others in that ‘metabolic type’ plan. I never bought into it because as mom in a house of 7, I couldn’t fathom preparing meals that were right for each different type. “I prepare real food, you eat. Be thankful if you can.” I am doing quite well on the Primal Blueprint diet. I am still struggling to get 100% grain free, but I have come a long way and I feel sooo much better.

I must admit, I had been undecided about the metabolic type concept. I assumed that perhaps some people did have more of a tolerance to grain-type carbs than others, and that this explained why some people eat a lot of healthy grains but avoid getting fat whilst others do not. But your explanation has focused my mind a little and I see now that perhaps it is is, as you nicely put it, hooey. One thing I decided was hooey the moment I first heard about it was the blood type diet. That one seemed flawed at the most fundamental… Read more »

Agree or disagree – you are always an insightful and fascinating read.

Of course, I totally agree with you.

Skip the diets; learn how to eat properly and live a healthy life and you will find so many challenges simply do not exist for you and you will be better equipped to deal with the ones that do pop up.

There. Now you can skip the newest diet-of-the-month-book and save your money.

I was interested to see this old saw of metabolic typing coming up again. Apes have blood type A and O and likely many other alleles. Only the most common one among many are used to type blood. What would be the reasoning behind the preference of type A for grains when apes have the same type? None whatsoever. Even if there were a preferred type for early farmers, and there isn’t, it would only be because it conferred some immune system advantage and have nothing to do with diet. Early farming, circa 11,000 years ago, exposed humans to new… Read more »

I’m surprised that Dr. Mercola pushes the MT diet so heavily. I generally trust Dr Mercola, and find his website to be full of great, paleo-friendly advice.

I never wanted to jump to conclusions about MT, since at first glance it does seem that some people can simply handle grains/carbs/whatever much better than others (like myself).

But it’s interesting to see you’re stance on the issue.

I followed the MT diet for years and it’s by far the best thing I could have done for myself health-wise. It just so happens, that I’m a protein type, so my diet is high protein and fat – very low sugar, grain free. MT doesn’t advocate grains for anyone – no matter your metabolic type. Different macronutrient ratios, sure, but it never goes as far as to recommend grains and straight up, refined sugar. I can (and do) follow the MT diet and a Paleo diet at the same time because they are very, very compatible (for protein types… Read more »

Dr Mercola does not advocate grains or sugar and minimal fruit no matter what metabolic type you are. The protein for carbon types is low purine protein vs high purine protein for protein types. I personally find Mercola’s metabolic types to make a lot of sense. I am a mixed type and have both types of protein paired with the appropriate vegetables and I feel better than I can remember feeling. Dr Mercola and Mr Sisson have very similar viewpoints on many topics ranging from essential supplements, sun exposure, going barefoot, etc. Both offer valuable information.

I just started eating higher purine meats more often since I discovered I am a protein type and its made a huge difference in my satiety. before i felt starving all the time and now can go 5-6 hours without even thinking about food. and im a foodie.

Just wanted to add to this too. According to the Mercola test I’m a carb/veggie type. In Mercola’s defence even with carb type meal plans, he still recommends mostly above ground vegetables, avoidance of gluten (good for me as I have celiac) and inclusion of animal protein with most meals. I find that if I follow his advice to start a meal by eating some of the vegetables before the protein, I feel a lot better in terms of energy and digestion. I also feel best if I avoid the “high purine” proteins he suggests are not so good for… Read more »

p.s. just wanted to add, I get why some would criticise the metabolic type theory, stating that it doesn’t make sense in a community for some people to eat differently to others in the group, but perhaps it is not unusual for some people to choose different ratios of the available food according to their natural preferences (I’m reminded of how I used to trade with my sister at meal times, giving her the fat of my lamb chops in exchange for more potatoes and veg!).

“Your ancestors’ place of origin may determine how your body burns calories, according to a recent study. In the study, researchers analyzed gene sequences from the mitochondria of 104 people. Mitochondria, present in all cells, produce energy and play a role in regulating metabolism. The DNA in mitochondria, which is inherited maternally, varies greatly by geographic region. People whose relatives came from cold, arctic climates have gene adaptations that allow their bodies to produce more heat while burning calories. On the contrary, those whose ancestors came from warmer climates tend to produce little extra heat and use calories more efficiently.… Read more »

It’s of course also interesting to note that the people who lived off the land ate what agreed with them. They were able to intuitively eat that which made them feel better and were never exposed to the varying “health viewpoints” that exsist today. They were not peer pressured into eating one way or the other, but in fact chose what was best for them.

Being an MT advisor, I think some of the value of MT is going unrecognized and I’d like to mention a few things. Even though all MT diet plans include whole grains and dairy, I believe that one of the main reasons why MT enjoys such great success is that it gets people eating whole foods instead of processed crap. I think that’s something we can all agree on. In my opinion, MT is not a contradicting alternative to the primal diet, but instead a more advanced implementation of it. I’m living proof of this because I follow both a… Read more »

Would it be possible that in ten thousand years of agriculture, some people have become grain-tolerant and less protein-tolerant? And that thus for some people eating carbs is not a health problem? Especially given that humans are pretty flexible, evidenced by existing in nearly all ecosystems. A smaller time span was sufficient to make most Europeans lactose-tolerant.

I really don’t understand why Mark is bashing the MT diet because I sat down and read the entire MT book yesterday and came away with the conclusion “this is pretty much the same as Paleo (Primal)”. I loved the book and I would describe it as recommending Paleo eating with tweaks to allow grains, legumes, and dairy only if you can tolerate them and they are BENEFICIAL for your specific genetic type. Even for “carbo types” they suggest limiting grains and beans and only eating them after soaking them overnight to remove phytates. Almost everyone is encouraged to eliminate… Read more »

I’ve read pretty extensively about the blood type diet (as well as the updated Genotype system), and after looking at the research published on D’Adamo’s site – based on an enormously sophisticated synthesis of medical anthropology, epigenetics, naturopathic medicine, and statistical analysis, I came away with the impression that while the idea is new, different, and yes, controversial – D’Adamo is not one to be mocked.

Waiting for a primal reply to metabolic typing. To be honest I think they are very close in philosophy. I love the idea of a paleolithic diet.

Strong evidence was given by Roger Williams, PhD (nobel prize for discovering vitamin B5 pantothenic acid) in his book biochemical individuality.

Its indeed very interesting and revealing that no “MT Basher” has responded with an intelligent retort since being presented with some substantiated reasoning. The initial arguments against MT clearly lacked the necessary research and understanding to make such statements and I hope those that seemed so convinced of the ridiculousness of MT will look into it a bit further. Its essentially just a bit more of a sophisticated progression on from something like the Paleo/Primal Diet anyway…and it works.

I’m sorry but when I read that you had to drag yourself across the floor to grab some OJ I lost it-that was hilarious….lol. But that doesn’t necessarily mean you shouldn’t be eating low carb, that could just mean that you’re so addicted to carbs that’s what happens when you stop eating them. The same way a heroin addict would feel terrible after giving up heroin-they would feel horrible initially but that doesn’t mean heroin is good for you.

Julia,

FYI, Mark doesn’t say to go carb free, he says to limit them. Low carb proponents I’ve seen recommend anywhere from 70 – 150 grams/day. Also you may have not gotten enough fat. You can’t eat all lean protein without fat. That’s “rabbit starvation.” You could eat 10 lbs of lean meat a day and still starve.

I do not think it matters that this site is coming up on MT google searches as anyone who reads the comments will realise that MT is a much more sophisticated method of working out what diets us as individuals should be following than the primal diet. here are some observations from me: 1) Mark and Rob Wolf have vested interests in the primal diet, so unfortunately (and very sadly) they cannot advocate the MT diet, no matter how much they actually agree with it (and from Mark’s arguments on this post, it seems that if he dug a little… Read more »

Tyler, I am Chinese and I’m wondering where you get the idea that Asians are carb types. Have you ever been to a 7 – 9 course Chinese banquet? I have been to many. The majority of dishes are animal: seafood soup to start, then beef, pork, chicken, duck, and shrimp. Usually 1 green vegetable dish, 1 noodle dish and of course rice. I have never done an MT test but I am definitely on the protein type side, but do fine with moderate amounts of rice.

Metabolic Typing is absolutely the best way to get your body on track. Yes, after being on it for awhile then one finds what adjustments are required. For me I needed a bit more fat. I’m a protein type. I’ve lost about 100 pounds in the last eleven years; the first 30 after I started using coconut oil and then the rest after I discovered the MT by reading Dr. Mercola’s email health updates. Yes, it went slowly but I never once “dieted”. Gradually my craving for sweets lessened and my appetite decreased. I lost a little every month until… Read more »

Yes, and your gradual weight loss is the inverse of the gradual weight gain that happens to so many people over an 11 year period. Seems like you have found what works best for you. 🙂

There are many aspects of Mark’s Daily Blog that I appreciate. One of them is that there is always great food for thought in the articles and the comments that follow. I value anything/anyone that/who encourages me to stop and think – to examine my own perceptions, to evaluate my belief system, or to change my behavior for the better. I don’t have a dog in this particular fight. I’m not emotionally, intellectually, or financially invested in anyone, or anyone’s hypotheses, being right – or wrong. And, make no mistake – everything from what our Paleolithic ancestors ate to what… Read more »

Hey Mark. I was wondering what your take on Weston A Price’s research regarding the different ethnic groups and their diets is. Basically, how can the traditional Swiss diet be so focused on dairy and comparatively little meat and veggies? How can some African tribes thrive on blood, meat, and milk alone? I have attached the link that I read on Weston A Price’s website, and I would love if you responded, because I am a little confused as to how Grok’s diet and those diet can be so different-did the neolithics evolve a new diet that we should look… Read more »

Such a shame. I was introduced to Metabolic Typing through college course work along with many other “diets”. MT is not really a diet, it’s a process to find out what each person is best suited to eat at that particular time in their life. It was the only methodology I have found to let the person dictate what foods are right for them rather than the Practitioner guessing or pushing their agenda. MT teaches you how to listen to your body and adjust accordingIy. I have seen people shift their needs as they went through the healing process. Whenever… Read more »

Excellent reply Michael, well thought about and explained. Shame to hear Sisson go on like this about a topic he obviously doesn’t fully understand. Makes me wonder about other posts he has made..
