The Blood Type Diet was invented by Dr. Peter D’Adamo and published in his New York Times best-seller Eat Right for Your Type. But what does the blood type diet actually entail, and does it really work? Read on to learn more about D’Adamo’s eating plan and whether it may help you shed those extra pounds.
The Blood Type Diet – Concept
The thesis behind the diet is that your biochemical makeup is directly related to elements like metabolism, ability to fight disease, and other aspects of your health and well-being. According to D’Adamo, following the diet and exercise plans that corresponds to your blood type can help you lose weight more quickly, prevent disease, and maintain greater health overall.
People with Type O blood are encouraged to focus on animal proteins and intensive exercise, and avoid dairy and gluten products. Those with Type A blood are presumed to have a predisposition to cancer, diabetes, and heart disease, and should focus on a vegetarian eating plan. Those with Type B blood are considered to be the healthiest and best able to combat disease, and fare well with exercises like hiking, running, and swimming and eating a flexible diet that includes low-fat meat and produce. People with Type AB blood are considered very biologically complex and should follow a combination of the plans for A and B types, and eat a diet that includes tofu and seafood.
The Blood Type Diet – Criticism
Critics of the diet plans outlined in the book note that D’Adamo doesn’t cite any peer-reviewed studies or scientific research that offer credence to the claims of connection between health and blood type. And though the book and related materials such as the official website mention ongoing clinical trials, results of these trials have never been published. In addition, while the diet touts itself as being individualized, the book makes no mention of factors such as age, health, weight, and other elements that may affect the exercise and diet plans therein.
The Blood Type Diet – Worth a Try
Despite the lack of scientific evidence, however, nothing in the Blood Type Diet is inherently harmful. That means that while eating and exercising based on your blood type according to the advice in the book may not be effective, there’s no reason why you shouldn’t try it if you are otherwise in good health and your doctor approves of your plans. However, note that diets can be quite restrictive depending on which blood type you possess, which means this diet can be more difficult than others that have been proven effective.
