What study? Where? I don't see a study anywhere. Is it like The Seven Countries study? You know, the one where corrupt researchers cut out all the studies that didn't fit their theory, left in only the ones that did, then marketed to the whole world that saturated fat and cholesterol is the cause of modern disease?
This is supposed to be an evolutionary diet, correct? Riddle me this:
Where did human life originate?
What foods are common to this area?
If your answers are "Equatorial Africa" and "Fruit, tubers and leaner game meats," you'd be correct.
Humans did not migrate to cold weather locations where fatty game are common until fairly recently. You almost certainly descended from people that subsisted largely on tubers, fruits and leaner meats most of the time.
Whole Health Source: Clarifications About Carbohydrate and Insulin
Small portions of traditional societies subsist on low carbohydrate diets. The overwhelming majority are starch eaters. Most traditional societies in existence today you will find in the tropics and Africa. They are diets rich in starchy roots and tubers, fruits, coconut, leaner meats and nuts. Most are fairly low protein, at least what I consider low protein (<20%).
Look, absolutely nothing you say has any factual basis. You have never provided a link to anything factual in your life. Your job here is to promote your line of thought. My line of thought is remarkably different from when I first started here 2 years ago. Feel free to look at my writings when I first started. The reason why my opinions changed was because I actually researched and experimented. You, clearly, are not interested in these things.
I'm surrounded on these forums by people that felt great when they first started this lifestyle, then their energy levels fell. Their hair started falling out. They get chills when they eat. They get ill when they have too many carbohydrate or dairy. And they just can't lose those last 20 lbs. And your answer is to keep doing what they're doing, clearly. It's insanity.
I invite you to read Danny Roddy's multi-part "Your Gut From Hell" and "Becoming Stress Proof" series here:

I also invite you to read Chris Kresser's article on how to CURE lactose intolerance. The reason why it's such a good read is the people with starch intolerance suffer from the SAME type of problem. It's a gut flora issue and an inability to process glucose efficiently thanks to your needlessly restrictive and unnatural diet.
