Although dieting makes you lose weight quickly, it does great harm to your health. I am on a diet, too. I used to go on a diet, but I looked terrible. Improper diet will make you fat. I exercise to lose weight, hula hoop, jump rope and do aerobic exercise for 30-60 minutes every day. If three meals are reasonable, it will gradually decrease. In short, we must persist. Don't use diet pills or anything.
