The Theory Behind Blood Type and Weight Loss


The Theory Behind Blood Type and Weight Loss

Before you dive into this article, please understand that there is no evidenced based research, as of yet, for the Blood Type Diet or the benefits the founders claim.

Due to the amount of questions Dietitians are always receiving on this topic I decided to discuss the research and findings of the doctors. That being said..let’s talk about the theory behind blood type and weight loss!

One of the most common questions people ask me about the blood type diet is whether they will lose weight or get in better shape. The science behind the blood type diet focuses on achieving your healthiest weight, or what I refer to as your ‘genetic’ weight (my clients have heard that term many, many times!). 

Achieving your healthiest weight happens when your body itself is healthy. This is something that many fad diets ignore and it’s not all about calorie restriction either!

When we simply restrict calories, regardless of the source (protein, fats, carbs) fat loss occurs but loss of active tissues mass (muscle and organ tissue) will also occur. The theory behind the Blood Type Diet is that if you eat correctly for your blood type, you will actually gain active tissue mass, increasing your basal metabolic rate, allowing excess fat to be burned away without losing any muscle. Thus, your weight loss will be consistent and you will increase your active tissue mass.

When your body is working properly, you build muscle naturally through daily activity and regular exercise combined with diet.

Main Weight Gain Factors:

  • Insulin Resistance
  • Intestinal dysbiosis
  • Thyroid hormone imbalance

  • Tendencies toward higher blood and cell viscosity
  • Bacterial overgrowth

Blood Type B

  • Liver detox dysfunction
  • Imbalanced microbiome

Blood Type AB

  • Bacterial overgrowth/dysbiosis
  • Cell-signaling issues
  • Stress
