The Blood Type Diet, created by naturopath Peter J. D’Adamo is centered around the theory that a diet based on your specific blood type could help you achieve your health goals. D’Adamo suggests that a diet designed for your blood type will result in your body more efficiently utilizing the foods you eat every day. There are many studies that both support and reject this claim.
Dr Melina Ratini offers her findings regarding blood type diets, “…adults eating the type A diet showed improved health markers, but this occurred in everyone, not just those with type A blood type. In 2013, a major review concluded that no evidence exists to support benefits of blood type diets, (however,) it’s likely that you would lose weight because the diet can be very restrictive.”
One identifiable flaw in The Blood Type Diet is a failure to address conditions such as heart disease, diabetes, or high blood pressure. Weight loss typically has a positive impact on these conditions, additionally, 150 minutes of exercise per week can strengthen the body’s defenses against these common maladies, so even if you proceed with your blood type diet, you can reinforce the diet’s results by also considering dietary guidelines set by the American Heart Association.
On The Blood Type Diet, you’ll avoid processed food and simple carbs. That may be enough to help you lose some weight. But any weight loss on this diet has not been linked to your blood type. There’s also no research proving that this diet can aid in digestion or give you more energy and although you’ll buy and prepare your own foods on this plan, your choices are limited depending on your blood type.
If the Blood Type Diet intrigues you, consider this: The science is stacked behind traditional recommendations for healthy eating for weight loss — not restrictions based on the type of your blood.
