even if you were doing the Master-Cleanse only to lose weight, it would be a benefit as long as you followed the instructions. The problem is that the weight won't stay off if you don't change your eating habits. That is why people who post that they are doing the Master-Cleanse only for weight loss usually get some posts in response explaining that although you will lose weight on the MC, it is a cleanse, not a "diet," and if your only goal is to lose weight, you'll have to make some major changes in your life to keep off the pounds you lose on the MC.
