If your blood is type "0" then you may have some trouble with thyroid. Get the book and see how you should eat to aid your thyroid to function at its best. If you are type "A" blood you need to be a vegetarian pretty much. The book I am talking about is "Eating Right for Your type" I have been eating for type "0" blood for 4 years now. I lost 30 lbs. and have kept it off. Got rid of all my health problems too. If I eat wrong I too gain weight but most importanly I do not feel as good. Beverly
