You have to experiment and find out what works for YOU. I know vegetarians who have lived healthy lives into their 90's. Won't work for me though. I seem to be doing better eating 150 grams of carbo a day or less. This is what Sisson and diabetic diets recommend. My PT calls grains "slave food" because thats what the Romans fed their slaves. As far as protein goes I do better with fish and chix. Probably due to my hereditary hemochromatosis. For me iron=death.
