The Blood Type Diet works by eating according to your blood type (O, A, B or AB). This diet idea was crerated by naturopath Peter J. D’Adamo. According to him, by following a certain diet for your blood type, it will help you lose weight, digest food properly, prevent diseases and gain more energy.

Does it work? There is no scientific basis for the claims made by this diet. The blood type diet has been found to be one of the worst diets.
