In fact, diet pills are not particularly reliable ... if you want to lose weight, don't be lazy. Roll your stomach more than 100 times a day. Eat three meals in a balanced way. Don't eat greasy chicken breast, it is low in fat. Don't eat sweets. Don't think it's okay to eat a little. A biscuit is enough for you to do hundreds of sit-ups. If you don't have much time for exercise, just lie on the ground and do sit-ups while watching TV.
