For people who take part in sports, there is only one word: eat! But eat at least 1 hour before you start exercising. This is to avoid digestive dysfunction caused by physical activity. Similarly, avoid eating indigestible foods, such as juicy vegetables and fried foods. Ideally, three meals a day and snacks can make the body replenish nutrition regularly.

If you only eat chocolate, that's not good. My impression is that it will turn sour. Suggest a diversified diet. Eat five to seven to succeed. Otherwise, it will be boring to exercise. If you eat 80% to 90%, you will be too tired to move. You should grasp the degree.

Then keep exercising every day, and you will lose weight. It's useless to move for only a few days.
