Did you know that you can lose weight based on your blood type?

The best way to lose weight is tailored to each individual's unique characteristics. In fact, weight loss methods are also related to blood type. Let's learn more about this below.

Nutrition comes from food. "A person's blood type determines the type of food their body needs," proposed Dr. Peter D'Adamo, a renowned American naturopathic expert. This blood type diet theory explains why many dieters repeatedly fail. Those who were previously confused about dieting finally see the light: by recognizing their blood type's dietary characteristics and eating the right foods, they can easily lose weight.

The four basic blood types—A, B, O, and AB—are derived from the inherent laws governing agglutination reactions of serum and red blood cells among different individuals. Similarly, blood type diets are based on the same principle. Foods contain a large amount of "exogenous lectins," proteins that can cause agglutination when they encounter different blood types, thus impairing energy metabolism, accumulating fat, and leading to obesity. On the other hand, some "exogenous lectins" can promote energy metabolism and prevent obesity.

Type A blood: Vegetarianism and appropriate exercise

Type A blood originated in the agrarian society's vegetarian diet era. Unlike type O blood, people with type A blood have lower stomach acid secretion, making them less able to digest meat. If they consume large amounts of meat without proper digestion, it can easily lead to fat accumulation and obesity. Therefore, people with type A blood who want to lose weight should be cautious about consuming beef, lamb, and other meats, opting instead for fresh fish and chicken. For those with this blood type who want to lose weight or improve their health, their diet should primarily consist of vegetables, especially soybeans and other legumes, with tofu being an essential component. Especially for weight loss, it's best to supplement with plant-based protein. Increase the intake of plant-based proteins such as tofu and grains in the diet to compensate for insufficient protein in the body.

Dietary recommendations:

People with blood type A are best suited to dining in a relaxed and pleasant environment. Because they are quite sensitive, an unpleasant atmosphere during meals can significantly affect their mood, leading to indigestion and potentially weight gain. The best way to lose weight is to set achievable goals, adopt a vegetarian diet, maintain a positive mood, and avoid tobacco, alcohol, alcoholic beverages, and spicy or strongly flavored foods. Nutritionists specifically recommend that people with blood type A drink a glass of papaya juice daily to help break down fats and harmful substances in meat.

High-quality weight loss foods:

Olive oil, sweet potatoes, spinach, and other leafy green vegetables.


Blood type B: Maintain a cheerful mood and eat smaller, more frequent meals.

Compared to blood types A and O, blood type B is a relatively recent blood type to emerge in human history, first appearing among nomadic peoples accustomed to changing climates and terrains. People with blood type B are generally physically robust, possessing a strong immune system that is easily balanced, and exhibiting strong resistance to many modern diseases such as heart disease and cancer. In terms of diet, they are arguably the most blessed blood type, as they can digest a wide variety of delicious foods, both animal and plant-based; they can eat almost anything. However, there are some foods they cannot tolerate, such as tomatoes, corn, chicken, and most nuts and seeds, as the hemagglutinin in these can hinder the metabolism of blood type B. For those with blood type B who want to lose weight, it is essential to follow the principle of eating small, frequent meals, maintaining a positive mood, and avoiding overeating and binge drinking.
