  • Degree of Difficulty / 0= Extremely Hard, 100- Extremely Easy/ 75% 75%
  • Level of Activity /0=Not included, 100= Activity is high/ 50% 50%
  • Water Included in Diet /0=Not included, 100= Built into plan/ 0% 0%
  • Maintenance Plan /0=No plan after initial weight loss, 100= Lifetime plan/ 100% 100%


The hypothesis for this diet is that the dieter needs to eat foods that were abundant where each blood type originated. There is not a lot of scientific evidence to support this premise, but it does stress that diets need to be specific to the dieter.

Ease for Dieter*


  • Easy if you already eat the category of foods recommended, otherwise it could be quite hard for a mostly carnivore to become a vegetarian or for a vegetarian to suddenly eat mostly meat.

(*My impression is based on my research and how hard I think it would be to maintain for 1, 6, 8, 10, 20 weeks. Your experience may vary.)

Food Emphasis

  • Limits are specific to your blood type.
    • Type A (Agrarian) – Eat a diet rich in plants and free of toxic red meat.
    • Type B (Nomad) –  Eat a diet of plants, red meat and some dairy. You shouldn’t eat chicken, pork, wheat, corn, lentils and tomatoes to name a few “toxic” foods.
    • Type AB (Enigma) – Eat a diet of seafood, tofu, dairy, beans and grains. You shouldn’t eat kidney beans, beef or chicken.
    • Type O (Hunter) – Eat a diet of high protein mostly from meat, fish and poultry. You can also eat some fruits, vegetables and certain grains, legumes and dairy.

Maintenance Plan

  • Undetermined. This diet asserts that as long as you stay on it you will lose pounds.

Suggested Activity Level

  • Activity level specific to blood type.
  • Levels range from low (Type A) to Intense (Type O) to rigorous (Type AB)
