Running-If you are nervous about your studies, you can do simple actions such as walking and twisting your waist. Running is too tired. Don't squat while sitting. If possible, you can have a rest and do simple yoga after dinner, 15 minutes or so. Action requirements are not high, just simple actions that can be done. Eat less greasy food, but don't fast and don't deliberately reduce your food intake.

If you persist in this way, the effect will be obvious after one year. But it needs to take effect in a short time. Sorry, this method is not suitable. The above methods are suitable for long-term slow reduction and no rebound.
