It is often difficult for people to associate blood type with weight loss. Nutrition comes from food, and people's blood type determines the type of food the body needs. Dr. Peter Dadamo, a famous American "natural therapy" expert, put forward this theory of blood type diet to lose weight and explained why people who lose weight often fail. The dieters who are falling like clouds have finally come to their senses. As long as you clearly know your blood type and dietary characteristics, you can easily lose weight by eating the right food. Four basic blood types, A, B, O and AB, are produced due to the inherent law of agglutination reaction between serum and red blood cells among different people, and so is the blood type slimming method, because food contains a large number of protein with "lectin", which will agglutinate when encountering different blood types, worsen energy metabolism and aggregate fat, thus making people obese, and some "lectins" can promote energy metabolism and prevent obesity. Type O blood: eat meat boldly and eat less whole grains. Because it contains more fruit acid, people with type O blood have strong working ability and immune system to respond to excessive food. Animal protein, that is, meat and fish, is indispensable in the diet of people with this blood type. Therefore, people with type O blood are boldly advised to lose weight and eat more meat. But you shouldn't eat fat, you should eat lean meat. Fish, cattle, mutton and chicken without chemicals in feed are all suitable. As for fish, nutritionists especially recommend eating oily fish produced in northern waters. Compared with the ability to digest animal protein and vegetables, people with type O blood are not easy to digest dairy products, beans, cakes and cereals, which is the ultimate reason for their obesity. Exoagglutinin in cereal will hinder the absorption of type O blood, accumulate body fat and gradually gain weight. Therefore, people with type O blood had better avoid rice for dinner, drink less dairy products at ordinary times, but take calcium tablets properly every day to supplement the calcium deficiency in the body. Usually pay attention to the balanced intake of vegetables, fruits and other foods to maintain the acid-base balance in the body.
