Lose weight quickly, which is harmful to your health. Losing fat is a long process, of course, it will be very simple if you just lose weight. Diet control+plenty of aerobic exercise. For example, breakfast (egg white+a purple potato), lunch (a tomato+an egg+a whole wheat) and dinner (if you are really hungry, eat half a cucumber) will make you lose weight quickly in 7 days. My previous experience, but not recommended, is easy to rebound. If you can't control your diet later, you will gain weight faster. It is suggested that you can combine anaerobic, aerobic and diet, so that you can lose weight and be healthy and beautiful. If you lose weight, don't care too much about your weight, just pay attention to the change of your circumference.
