For example, people with type O blood are advised to choose high-intensity aerobic exercise and take supplements for their sensitive stomachs, while those with type A blood should choose low-intensity activities and include meditation as part of their routine.
High-quality studies about the blood type diet had not been published in peer-reviewed medical literature. Studies published in and about the blood type diets are worth noting. The study found that while people following any of the blood type diets had some improvement in certain cardiometabolic risk factors such as cholesterol or blood pressure , those improvements were unrelated to blood type.
The theory behind this diet is that blood type is closely tied to our ability to digest certain types of foods, so that the proper diet will improve digestion, help maintain ideal body weight, increase energy levels, and prevent disease, including cancer and cardiovascular disease. Type O was said to be the original "ancestral" blood type of the earliest humans who were hunter-gatherers, with diets that were high in animal protein.
Group A was said to evolve when humans began to farm and had more vegetarian diets. Group B blood types were said to arise among nomadic tribes who consumed a lot of dairy products. And since Group AB blood was supposed to have evolved from the intermingling of people with types A and B blood, type AB recommendations were intermediate between those for people with types A and B blood.
Each of these theories has been challenged. For example, there is evidence that type A was actually the first blood group to evolve in humans, not type O.
In addition, there is no proven connection between blood type and digestion. So, in addition to a lack of evidence that the diet works, serious questions remain about why it should work in the first place.
Eating based on your blood type requires you to know your blood type and then follow a restrictive diet. Personal preferences might be a problem: a vegetarian with type O blood may struggle to stay on the assigned diet, and people who love red meat may be disappointed to learn they have type A blood.
Recommended supplements are not cheap; neither are the recommended organic foods. Before cutting them out of your diet, however, speak to your doctor to be sure that eliminating them is the right choice for your health. And be aware that there is no scientific evidence demonstrating that your blood type affects the type of diet you should follow.
Ultimately, it doesn't matter whether you have B positive or B negative blood, the foods that you shouldn't eat, including meat, are the same. While you're encouraged to eat lamb, venison, rabbit and fish, you're discouraged from eating chicken and pork. You should also skip other types of poultry such as duck, according to the Everydiet website, though you can eat small portions of turkey.
D'Adamo also recommends that you also don't eat shellfish such as lobster, crab or shrimp. You should also limit how much beef you eat if you have type B blood. They are also encouraged to eat organic and fresh food in as natural a state as possible. They should avoid certain foods — like corn, wheat, buckwheat, lentils, tomatoes, peanuts, sesame seeds, and chicken — and instead opt for goat, lamb, mutton, rabbit, green vegetables, eggs , and low-fat dairy products. They should avoid caffeine , alcohol, and smoked and cured meats, and try to eat more small meals throughout the day, according to the diet.

The Blood Type diet forces you to take a good look at what you eat, which is an eye-opening experience and will typically motivate change.
