First of all, it depends on your diet. You should control your carbohydrate intake. It is best to try to reduce or not eat fatty foods, eat as little as possible at night, and eat breakfast, otherwise eating too much at lunch will accumulate fat. Moreover, the weight gained at the beginning is not necessarily fat, because it takes time for fat metabolism at the beginning of exercise, and a certain amount of exercise needs to be accumulated and gradually reduced. But at this time, because of exercise, the muscle density will increase, the weight will temporarily increase, and the weight will slowly decrease, so it is necessary to persist.
