No one can deny that The Master Cleanse will usually produce a rapid loss of weight. The problem is that losing and maintaining weight loss is not a single diet, it is a change of lifestyle. It is useless to depend on the Master-Cleanse alone to keep the weight down; however combining The Master Cleanse with a lifetime commitment to proper diet and exercise will help give you a slim healthy body that can be kept for life. There are no quick fixes in health or weight loss. The Master Cleanse is valuable for both, but you must be willing to change your lifestyle to really reap lasting benefits.
