If the above questions are all right, then I suspect there are two reasons why you can't lose weight.
1. Physiological diseases
Generally, people who can't lose weight either don't lose weight well or have diseases in some parts of their bodies. This is not for fun. There is such obesity in the world. Even if you drink boiled water every day, you will grow a hundred pounds, even as heavy as a pig. Believe it or not, on the contrary, it won't change the fact.
There is a big fat man in my village, thirty-five years old and not married. The problem is his height and weight. He is only 1.5 meters tall and weighs 170 Jin. What concept? He was so heavy and poor that he never got married.
You should make sure that your exercise is not just a day's fishing, and your diet is not limited to how many meals you eat. Have enough food for every meal, and then think about whether there is something wrong with your body. I advise you to take the time to go to the hospital for a check-up, and everything will come out.
2. Family inheritance
The second reason is not impossible. Some people are born skinny, while others are born fat as pigs. If we rule out the first reason, we must find the reason from home. You can ask if any relatives in your family are born fat. If so, you should leave it to fate. In addition to a healthy diet, if they are not really fat, don't take vicious measures to force themselves to lose weight.
Don't say there is no family inheritance. I have a junior high school classmate whose family situation is very good, but he just can't get fat. She is 1 m 53 and weighs only 70 kg.
