There are liver cleanses, colon cleanses, kidney cleanses -- they can be very good for health, but not very useful for
losing weight in a healthy fashion because the
weight will just come back as soon as you return to your normal way of eating. The only way to lose weight long-term is to change your metabolism, which doesn't involve calories as much as it involves what you eat and how quickly it turns into sugar and how easily it moves through your digestive system.
