What are the fundamental reasons why thin people can’t gain weight?

Many thin people will say that they will not gain weight no matter how much they eat. In fact, it is not that they will not gain weight, but that they have abnormal symptoms in their bodies. From a clinical perspective, the fundamental reasons why thin people cannot gain weight include poor stomach absorption capacity, irregular living habits, excessive life pressure, etc. In addition, it is also directly related to genetics and certain diseases. Therefore, if thin people cannot gain weight, it is best to go to the hospital for a check-up.

1. The stomach’s absorption capacity is poor. This is mainly related to the gastrointestinal tract. If there really is a problem in this regard, the food people eat will be excreted from the body before being digested, and people will naturally not gain weight. The most important thing is that such people need to be well-conditioned to improve their physical fitness.

2. The relationship between genetic factors. Since the parents themselves are not fat, their children will also be thin, but there are exceptions. If this is the reason, then it is not easy to gain weight. Even if you eat a lot of meat and fish and more sweets, the effect will not be obvious.

3. Irregular living habits. People often disrupt their daily routines due to work. Because of busy work, sometimes you skip lunch or breakfast, so your nutrition is not enough and of course you won’t gain weight. However, doing this in the long run will have adverse effects on your gastrointestinal tract. Some people get chronic gastritis this way, and when you really want to eat, your stomach doesn't work. Therefore, try to ensure your meal times and eat all three meals, even if it's only a little.

4. Related to disease. Certain diseases in the human body can cause people to lose weight. For example, hyperthyroidism and diabetes. These two typical diseases are the main causes of weight loss, and the changes are obvious and easy to notice by yourself.

5. Too much stress in life. Sometimes, in order to complete the tasks assigned by work, I will have greater pressure, which will lead to mental tension. On the one hand, it will cause too little food, and on the other hand, because of emotional reasons, it will weaken the digestive system function and reduce the absorption rate.

Therefore, no matter what the reason is, keep a good mood every day. If it doesn’t have much impact on your life, don’t worry and take your time to adjust. The most important thing is to take good care of your stomach, pay attention to your daily routine, go out for a run more often, and strengthen your physical fitness.
