Diet to reduce weight for b positive blood group?

Ignore that stuff. During the 1990's, a crooked physician published a series of books suggesting different lifestyles and diets for different blood groups. It was totally made up. It's rubbish. For weight reduction, it's small portions, avoiding greasy / salty / sugary stuff, enough protein, and finding and doing exercise that you enjoy, preferably with friends. All the rest is hogwash. This will free you up.
