If you want to speed it up try " the Carbohydrate Addict diet Plan". it can be modified perfectly for Type O's. It took me 8 months on combination diet to lose 10 lbs...but they were very resistant pounds since that's all I had to lose and I ate like a horse! Ironically, after that weight loss, I went off my diet because I started losing too much weight ( every week) and got scared.
