Hi, did you hear about a diet based on our blood type? 1 specific diet is not working for all people. Every individual needs his own diet, optimal for him. If you are interested you can google your blood type and diet based on that type! I can eat a lot of food that is optimal for my type and i don't gain any fat. But if i eat some food inappropriet for my type, even if it's considered healthy, i gain some fat :)
