Does the Blood Group Diet Actually Work?

For those of you who haven’t yet heard about the blood group diet, it’s the new big hit with the celebs. The diet has been created by neuropath Dr. Peter D’Adamo, who claims that the best diet varies according to your blood type. Big Hollywood names including Liz Hurley and Cheryl Cole are fans of the diet, agreeing with the doctor in his claims that the diet encourages weight loss, increases energy levels and makes you feel healthier. Nutritional and medical experts however are not so convinced with many saying that the theory behind the blood group diet is nonsense. According to Dr D’Adamo our body deals with different food types and nutrients in a variety of ways depending on which blood group we belong to. Each blood group has it’s own antigen marker. This is a substance that the body doesn’t recognise and reacts badly to. The theory behind the blood group diet is that this antigen marker reacts badly to certain foods causing health problems. Additionally he believes that digestive enzymes and stomach acidity are connected to blood groups. Therefore a diet should be designed around blood type, which will allow your body to digest and absorb nutrients most effectively and result in weight loss. Dr D’Adamo also believes that blood types developed and evolved so he designed the diet based on what our ancestors ate when a new blood type was first discovered. Blood group O, is thought to be the first blood group to be identified, back in hunter-gatherer times. It may not be too hard to guess then, the blood group diet for type O’s, the most common blood group in the UK, mainly consists of meat and fish. Dairy products, wheat and grain should be avoided. Regular dieters will realise that this is basically just a high-protein, low-carb diet, similar to many, which have become popular in recent years. Of course this diet should be combined with plenty of exercise to mirror the activities of those hunter-gatherer ancestors!

By the time blood type A had been discovered, our ancestors had begun farming so were eating plenty of vegetables and grains but not so much meat. The blood group diet for type A’s individuals then is strictly vegetarian and dairy products should still be avoided. Fruit, vegetables, pasta, rice, nuts and seeds are some examples of what this blood group diet should consist of. Exercise should be gentler and Dr D’Adamo recommends golf or yoga.

Blood group B definitely has the best diet, as there are hardly any restrictions. By the time this blood group was discovered our ancestors were fairly developed with the means to travel allowing them to eat a mixture of food. So the blood group diet here is fairly balanced with the only thing you are supposed to avoid being processed foods. In terms of exercise, sports which also contain an element of thinking are recommended such as tennis and swimming.

Finally Blood group AB should follow a mixture of the blood group diet for both A and B. Exercise should also be varied between intense activities and more relaxed ones.

Medical experts around the world have agreed that this theory doesn’t make much sense. There has not been any strong scientific evidence to suggest a link between our blood type and the food we should eat. Everyone required a balanced diet in order consume the essential nutrients and vitamins regardless of their blood type. You may lose weight doing this diet, but that is down to cutting out many important food group not because it is a perfect blood group diet and ultimately you could be damaging your health rather than improving it.
