Paleo and Body Type Theory?

Coming from a bodybuilding background were the Body Type Theory used frequently, I was wondering what the Paleo Community thinks of this theory. Here is the basic idea:


An Endomorph's biggest concern should be the losing of fat and adopting a lifestyle that keeps it off. Strength training should be done to get a better muscle to fat ratio and therefore improve metabolism. Use moderate weights at a fast training pace (very little rest between sets and exercises). You should lower your calorie intake (but not try to starve yourself) and should eat frequent but small meals. Sugars, sweets and junk food should be eliminated from your diet. Engage daily in some activity like brisk walking, biking, etc., and try to increase the amount of time you spend each week.

Examples - soft body, flabby, underdeveloped muscles, round shaped, over-developed, digestive system, trouble losing weight, generally gains muscle easily.


A Mesomorph has a naturally fit body but to maintain it or improve it they should exercise and diet corretly for their type. Strength training can be done more often and for longer sessions then would be good for an Ectomorph, but you must still be carefull not to overdo it. You should train with moderate to heavy weighs and at a moderate pace, not resting too long between sets. You will find you gain muscle quite easy (some women and even men might not want to get too bulky, but this won't happen suddenly. When you are happy with your muscle size simply train to maintain it). Stick to a good healthy diet to keep you lean and muscular, and watch for any slow creeping fat gains. Engage in and enjoy aerobic activities, sports, etc. but do not overdo.

Examples - athletic, hard, muscular body, overly mature appearance, rectangular shaped (hourglass shaped for women), thick skin, upright posture, gains or loses weight easily, grows muscle quickly.


Ectomorphs should concentrate on gaining weight in the form of good lean muscle tissue (some women that are too thin may also want to put on a little fat to look more feminine). Weight training should be done but not too often or for too long each session. Weight should be fairly heavy and workout pace slower (longer rest periods between sets). Diet should be high in calories (good quality food not junk) and you should eat more then you're used to and often. Aerobic and other activities (sports, dancing, etc.) should be kept to a minimum, at least until you are happy with your weight and looks.

Examples - fragile, thin, flat chest, delicate build, young appearance, tall, lightly muscled, stoop-shouldered, large brain, Has trouble gaining weight, muscle growth takes longer.

There are some who believe you can be a hybrid of the two as well.

well the reality is that every person is genetically wired differently. You could divide the whole population into these three groups, but what good does it do?

jees not sure I believe in this, doesn't really fit in with Art de Vany's Evolutionary Fitness ideas either - I guess his training is more like mesomorph, which works well for him.

I easily fit into the Endomorph category. It looks pretty straightforward, and I don't see much (if any) difference from other Paleo theory I have read on weight loss.

I have read about this before. I'm surprised you haven't gotten a response yet. I'm interested to know as well, now. After reading it, I think I am a mesomorph.
