Changing Diet

I don't mean to eavesdrop. But I did overhear a couple of ladies talking at the next table earlier this week. They were discussing about the best way to lose weight. And one of them was advising the other to change her diet to suit her blood type. Yup. You heard me right. Diet according to one's blood type. I thought it was rather novel too. And it seems that the lady can't eat protein, can't eat dairy, can't eat a whole load of stuff. Gosh! That seems rather torture, right? I was thinking to myself that I would just get the best weight loss product, to achieve my ideal weight rather than her recommended method.
