Blood Type O Dietary Needs

Foods that Promote Weight Gain

Refined grains, wheat gluten, white flour, sugar, sweet corn
Can cause insulin resistance/slow down metabolism

Slow down metabolism, disrupt ability to burn calories and lose weight

Brussels sprouts, cabbage, cauliflower, corn, lima beans, sweet potatoes
Inhibit thyroid function

Sugary, fatty, fried food, fast food, high-pesticide food, saturated fats, excess sodium (salt)
Slow down metabolism

The leading cause in weight gain for type O’s is gluten, a protein composite found in foods processed from wheat and related grains. Gluten lectins inhibit type O’s insulin metabolism, interfering with the efficient use of calories for energy. Sweet corn has the same effect, although it’s not nearly as influential as wheat in precipitating type O weight gain. Certain legumes, especially lentils and kidney beans, contain lectins that deposit in muscle tissues, making them less “charged” for physical activity.
