Type O-People with type O blood fare best on intense physical exercise and animal proteins and less well on dairy products and grains, says Dr. D'Adamo. The leading reason for weight gain among Type O's is the gluten found in wheat products and, to a lesser extent, lentils, corn, kidney beans, and cabbage, Dr. D'Adamo explains. Ideal exercises for Type O's include aerobics, martial arts, contact sports, and running.
