What Researchers Found About The Blood Type Diet

Nutrition

When it comes to weight loss, it seems like we’ve tried all the diets to get the weight off. From going vegan, trying the Mediterranean diet, or even going Pescatarian. No matter what you try, (or fail within three weeks of trying) you aren’t seeing or feeling the results you wanted too.

What else can you try to help you live better? There’s a diet you’ve probably heard about that some are considering only a fad. This fad is known as the blood type diet.

The promise

The blood diet, according to naturopath Peter J. D’Adamo, claims that by following a strict diet based on your blood type, you will be able to digest food more efficiently, you’ll lose weight, have more energy, and help prevent disease. The following list includes the diet regimen basics your blood type should follow:

  • Blood Type A: Meat-free diet that focuses on organic fruits and vegetables, beans, and whole grains.
  • Blood Type B: Green vegetables, eggs, certain meats, low-fat dairy.
  • Blood Type AB: Tofu, seafood, dairy, and green vegetables. No caffeine, alcohol or smoked meats
  • Blood Type O: High protein diet that includes, fish, lean meat, and vegetables.

These cringe-worthy diet restrictions of the blood diet severely limit the varieties of food one can eat and still live a healthy lifestyle. Examine Blood Type A; apparently, you must eat only fruits and vegetables – with no meat. So, Type A has to give up meat to be completely healthy. Does this diet plan have any statistics backing it up as a proven diet worth trying?

Evidence?

A Belgian meta-analysis (systematic review) of sixteen studies (screened from over 1,400 candidates) published in The American Journal of Clinical Nutrition looked hard to see if there’s any known proof that the blood diet has some benefit to the human body. After this seemingly exhaustive search, they concluded that the diet has no scientific evidence to back up its claims of bettering your health, despite its massive presence in the health industry.

In another study scientists evaluated approximately 1500 people and gave them a score based on their adherence to the diet’s regimen. The results concluded that there was zero association between a person’s blood type and health benefits from the prescriptions of this diet.

Do what works

The goal of this article isn’t to discourage you from trying another diet. Just be careful what you select. Science is about correlation (none found in this diet) and causality.

Although there is no apparent evidence of correlation or causality here, that doesn’t mean you can’t pick a “blood type” to follow and lose weight. If you like the food in a diet, don’t be afraid to try it!

Losing weight is a great goal for many reasons, including the reduction of back pain and your overall joint health. Look better, feel better, live healthier.
