Nanciesweb-Controversing both yours and Dr Mercolas opininion: I don`t believe in some distinctly different nutrition types . I think that about 3 years experience from Sweden contradict that .Sure there are some different genetical weaknesses but not more than that. Basicly we all are quite equal. The basic problem is that we not are fully adapted to agricultural food-especially not when excluding proteines and saturated / singel-unsaturated fat.These are essentual to all human beeings.Carbs are not. Your liver produce carbs out of the former ones when necessary for the brains demandings.    

When eating more proteins and fat (you need to combine them) you will eat less carbs-and then you`ll go in the right direction! To much carbs cause high blodinsulin-getting you fatter-high blodinsulin prohibits fat burning and then you are on the way to obesity,diabetes 2 and several other metabolic-syndrome-deseases. So it works! In Sweden it`s proved! In the US too. Dr Mercola can explain this too,I think!
