Because you just started exercising, your body will store some water and nutrients to prepare for long-term exercise in the future, and your weight will inevitably rise temporarily. As long as you keep exercising reasonably for a period of time, you will lose weight.

First, there is a large amount of exercise and a large appetite. Some people just started to lose weight by running, and then they lost weight again after a period of persistence. This is because running can stimulate digestive organs and increase appetite while consuming energy substances. At first I was able to control my diet and lose weight. After a while, because of the unbearable hunger and the novelty of losing weight, I simply overeated and gained weight.

Second, we can't persevere. Some people stop exercising after running for a while because they lose interest. We should know that the digestive system changes more slowly than the exercise system, and the energy consumption is obviously reduced after stopping exercise, but the absorption function of the gastrointestinal tract remains "vigorous". Of course, if you weigh it, you will gain weight.

Extended data:

Weight control programs can use four therapies: diet and nutrition counseling, behavioral therapy, drugs and surgery. Nowadays, traditional dietotherapy is rarely used; Instead, it emphasizes changing long-term habits. Most programs teach customers how to eat safely, wisely and step by step.

Changes include increasing the intake of complex carbohydrates (fruits, vegetables, bread, cereal products and pasta products) and reducing the intake of fat and simple carbohydrates. A very low-energy diet of 400~800kcal per day is not so popular, because it is obvious that patients can regain their weight quickly.

Because people's weight is related to many factors, there are differences between different people, and there will be certain changes at different times of the day. In addition, geographical location (such as gravity), season, climate and one's own situation also have certain effects on weight, so it is difficult to reach the standard weight completely.

In other words, it is difficult to express it with a constant value, but it should be a range of values. We call this numerical range a normal value, which is generally within 10% of the standard weight. Beyond this range, it can be called abnormal weight.
