Why you won't get fat if you eat too much:

1. The high basal metabolism may be the reason why some people eat crazily but are not fat. However, if the basal metabolism is obviously high, it may also be a manifestation of the disease. For example, people with hyperthyroidism often have goiter, bulging eyes and hot flashes on the skin, so the higher the basal metabolism, the better.

2. The heat production capacity of mitochondria determines the energy consumption level of human body. Studies have shown that some people have genetic variation in their mitochondria. Such people have a strong ability to burn heat, but the efficiency of using heat is very low. Some people eat too much because of mitochondrial variation.

3. The difference of intestinal flora is probably an important reason why some people get fat when they eat, and some people don't get fat when they eat. We often say that people who eat too much and are not fat have poor digestion and absorption ability, so the food utilization rate is low. The root cause may be that their intestinal flora is different, which leads to different heat absorption rates. Generally speaking, the gene number and richness of intestinal flora in people who are overeating and not fat are higher than those of normal weight.

4. Family genetic reasons. If parents are thinner, offspring are more likely to be thinner, and if parents are fatter, offspring are more likely to gain weight. Genetic traits may play a very important role in whether a person can gain weight, and its specific mechanism may be quite complicated.

When we talk about people who overeat without getting fat, we usually mean in a short time, not for a long time. After all, there are really few people who overeat for a long time and are not fat. If there is, it is probably not a normal physiological phenomenon, but a pathological state.

So don't envy people who eat too much and are not fat. After all, people who eat too much are a minority. For most people, eating too much is easy to get fat. If you want to eat and lose weight, you must lose weight, especially a healthy weight.
