What is the Blood Type Diet?

With the obesity epidemic growing ever larger, new diet crazes are sweeping the world with recommendations to help you get slim and trim. Some of these diets are proven to not work, while others may lead to initial weight loss, but the pounds come right back after the diet is over. Could the blood type diet be the answer to losing weight however? And what is the blood type diet?

The Blood Type Diet Explained

Peter J. D’Adamo, a naturopath, proposed that eating foods geared toward your blood type may be the key to losing weight. His reasoning was that each specific blood type reacts differently to food than other types. By eating the food your blood type handles most efficiently, you can lose weight and feel healthier too.

The blood types are divided up as follows:

  • Type A diets
    Type A’s should choose a mainly vegetarian diet, avoiding red meats and pork, with only occasional seafood or poultry. Type A’s are encouraged to eat tofu, vegetables, fruits, whole grains and legumes.
  • Type B diets
    Type Bs are encouraged to eat a wide variety of different foods, including meats, dairy, fruit, vegetables and grains. Limit corn and wheat to help in weight loss.
  • Type AB diets
    AB also benefits from an omnivorous diet, but eating kelp and green vegetables is recommended for weight loss, while avoiding kidney beans and buckwheat.
  • Type O diets
    This diet best resembles the paleo diet, and encourages eating meat, fruits and vegetables while reducing grains, beans and legumes.

Does it work?

The simple truth is these diets are all much healthier than the ones we choose to eat normally. Even if you are a type O and you are consuming a type A diet, if your previous diet was the typical Western diet, you will still probably experience a boost in health and weight loss.

Any diet that includes fresh foods and fewer processed meals is going to be better for your health. A study of the blood type diet showed that while it was associated with better health, it wasn’t the blood type specifically that caused it. A follow up study however, shows that blood type does play a part in certain food related diseases (such as ulcers) and that diet can control these. With that in mind, it is safe to say that more studies need to be done before the answer on whether eating for blood type is useful can truly be reached.

As for whether or not you should follow this diet, there is no reason not to unless you have a specific health problem that needs to be controlled with food. You should see a doctor before changing your diet and weight loss routine, and asking them about the blood-type-diet, and what that includes if they don’t know, will be advisable. (You’ll need a blood test to find out your type anyway, so you might as well ask while you’re there. Or test yourself using a home blood type test kit)

Why You Should Know Your Blood Type?

Regardless of whether you are on a diet or not, you should really know your blood type. You never know when you might find yourself in an emergency situation where this information might be useful. It’s a scary fact that more people know their astrological star sign than their blood group!

For many people, the process of finding out their blood type happens when they go to give blood.
