If it doesn't work, it will rebound! Exercise more, but don't lose weight because you are too lazy. If you have money to sign up for a weight loss class, it is better to sign up for a fitness class! Don't believe in diet, medicine, massage and beating people in society. It will only make you rebound and get fatter. You are not allowed to eat this and that. Seriously affect your health! Just look for it, exercise more, be afraid of hardship and sweat more. Just stick to it. The fatter you are, the lazier you are, the less you want to exercise, the less you exercise, and the fatter you are.
