I'm honesty not sure really! I know I have poor circulation (I can tell by the white and red patches on my skin after comming out of a sauna or a really hot shower) I look anorexic, but I sure am not! *lol* I eat like a pig ;) I follow a similar diet to the one suggested here: little to no processed food, very little red meat, lots of fruits and veggies, only natural Sugar in small quantities, no dairy and I am able to eat grains. I lost weight *gah*! It give you that same kind of self concious feeling that I am sure overweight people have :( Atleast a lot of overweight people can control their weight with a proper diet. I tried to eat a lit of whey protien for awhile but I didn't notice it do anything and it tasted nasty! Not really too sure what to do or if I can even do anything.
