The Blood Type Diet was created by Dr. Peter D'Adamo, who claims that your blood type determines the right foods for your health 1. There are four blood types and each one should emphasize certain foods and should avoid others. D'Adamo claims that the diet will result in weight loss and will also improve your overall health. Always talk with your doctor before beginning a new diet program.
Type O
The most common blood type is Type O, and D'Adamo claims that people with this blood type are more prone to metabolic issues and weight gain than other blood types 1. This blood type should eat a diet that is low in carbohydrates and high in protein 1. Foods that are recommended for weight loss for type O people include sea kelp, seafood, red meat and vegetables that include kale, spinach and broccoli. Specific items that you should not eat include, avocados, cabbage, corn, eggplant, mushrooms, olives, melon, oranges, blackberries, coconuts, strawberries and tangerines.include:

People with Type B blood are able to digest a wide range of foods, but should still avoid some of them because they could contribute to weight gain 1. This includes corn, buckwheat, lentils, peanuts and sesame seeds. Blood type B also requires avoiding gluten products due to their effect on blood sugar 1.
Type A
Blood type A individuals have a more sensitive digestive system than other blood types, and D'Adamo recommends a primarily vegetarian diet 1. If you have blood type A, avoid meat and dairy foods and focus on whole grains, fruits and vegetables 1. Foods that help with weight loss for this blood type include, vegetable oil, soy foods, spirulina, vegetables and pineapple 1.include:
