The blood type diet emerged in the late 90s and grew wildly popular in a short time. It has experienced a considerable dip in popularity since then but still has some loyal followers. Celebrities like Demi Moore, Liz Hurley, Cheryl Cole and even Australia’s very own Miranda Kerr have tried it, but scientific evidence is still awaited.

In this article, we will discuss how to eat right for your blood type and what you can hope to see by doing so.

What is a blood type diet?

This diet was created by Peter D’Adamo, a naturopathic doctor in 1996. He believed that each individual reacts differently to the food they consume, depending on their blood type and biochemical makeup. He published a book called Eat Right 4 Your Type which went on to become a wild success, leading to the spread of the blood type diet.

The book and the diet suggested that your blood type is the biggest factor that determines how your body will react to food, stress and exercise. It can also explain your gut bacteria and predict your susceptibility to diseases and health conditions.

What are the benefits I can expect from a blood type diet?

According to the blood type diet, consuming foods that are incompatible with your blood group lead to a large number of health issues. When you consume food that has negative interactions with your body, it can activate the immune system and place unnecessary stress on the body. If you eat right for your blood type and follow the recommended lifestyle changes, you can experience the following benefits:

  • Reduced digestive issues
  • Weight loss
  • Improved energy levels
  • Prevention and improvement of chronic diseases

This diet recommends regular exercise as one of the prime lifestyle changes and so it allows for all the different benefits that one experiences from an exercise regimen as well.

Unlike most other ‘one size fits all’ diet approaches, this diet focusses on personalized nutrition, allowing you to eat right for your blood type. This interaction of food with the blood type could partially explain why specific diets like Keto or Atkins work for certain individuals while others struggle with the same.

Another benefit of this diet is that it considers not only the foods you should be consuming but also how you respond to stress and exercise. This encourages you to create a suitable lifestyle and stay attuned to the needs of your mind and body.

How do I get started with the blood type diet?

If you are considering taking up the blood type diet, you can consider the following steps:

Know your blood group
This can be done through a blood type kit or by consulting your medical practitioner. Once you have determined your blood type, you can make the adjustments to your lifestyle and eat right for your blood type.

Learn more about the diet
You could refer to the source and read the book Eat Right For Your Type written by the creator of this diet.

Make gradual changes to your diet
You could start by incorporating a few foods that are highly beneficial to your specific blood type. Gradually increase other foods that are suited to you whilst making sure to avoid all foods that are detrimental to your health as per the diet. 

Consider taking the supplements suggested by the book
There are a number of supplements that are designed specifically for each blood group which you could take to improve your health.

Exercise as per your type
Regardless of its name, the blood diet makes lifestyle changes based on the belief that individuals respond differently to exercise regimes. Choose the exercises that are best suited to you. If you do not exercise already, it is best to start gradually and slowly increase your fitness as your body begins to adapt.

It is natural to feel overwhelmed. Take it slow and ease into the many suggested changes.

If you have any pre-existing medical conditions, do consult your medical practitioner before committing to any big lifestyle changes.

Get a family member or a friend to take up the diet with you. Having someone on this journey makes it easier for both of you to stick with it in the long run.

Gradually incorporate all the ‘good’ foods while eliminating all the ‘bad’ ones.

Do not be too hard on yourself and stop immediately if it doesn’t feel right.

It recommends avoiding the following:

What does science have to say about the blood type diet?

There are not enough scientific studies or clinical trials to back the claims of the blood type diet.

The most severe criticism against this diet is that Peter D’Adamo, the creator and advocate of this diet was using it as an excuse to market a brand of exorbitant supplements that were centered around this diet.

However many people have reported feeling healthier and losing weight when they followed a diet suitable for their blood type.

What should I know before commencing the blood type diet?

This diet imposes severe restrictions on the foods that can be eaten by the three common blood groups. While the reduced calorie intake can lead to weight loss, it can also lead to severe nutritional deficiencies which can have a negative impact on your health.

However the diet prescribes some basic healthy principles: exercising, understanding the needs of your body, and finding proactive ways to deal with stress. Whether you choose to eat right for your blood type, these are good fitness practices to follow at all times.
