loosing and keeping the weight off!

Hello eveyone.I want to know has anyone on this forum lost weight on kept it off.I mean after the cleanse resuming eating and exercise on a regular.It is possible and attainable?I think that it does not matter what mathod is used,if one returns to what made them overweight and unhealthy in the first place then they are dome to fail.I just want to hear from people who have done the master cleanse,lost weight and have kept it off.thanks..........
