I've done some reading on "Metabolic Typing" diets that suggest that some people do better on a diet that includes more low glycemic index friuts, grains, and legumes....these people, they suggest, would not do well on a low-carb/high fat diet. Has anyone here tried this type of diet? Does anyone have an opinion as to why low-carb is better? As a bodybuilder and avid exersize fanatic, I have tried both....but for health, I didn't need to lose weight. I found that I lost too much strength and too much weight on a diet that was low in fat and moderate on good carbs despite eating plenty of calories. I have actually gained weight, following a low carb plan religiously, with very little of that gain in bodyfat. Does anyone have any thoughts on this?
