I plan on maintaining and losing more weight once off the cleanse. By eating less food. I do like some veggies. I don't see how a person gains it all back if they continue to diet. I am not going back to the way I ate in the past. I have heard I will gain some back, which I expect.
Diets are not good for you and they ultimately fail. The fast will slow your metabolism considerably and when you start to eat again, your body will hold on to calories relentlessly. Your body goes into starvation mode when you fast/diet so that any calorie intake will be hard to lose. As you get older your metabolism will naturally slow down and if you add fasting to this, you just have a recipe for disaster.
Your best bet is to utilize the cleanse for what it was intended for: to clean out built up toxins, rebuild and begin to establish a new relationship with food. Also, find a healthly eating plan and to exercise. If you really want to be healthly, you have to include fruits and vegetables in your diet. They are Nature's remedy for what our bodies truly need. This will ultimately keep the weight off for good.
I have done The Master Cleanse many, many times and the only eating plan that keeps the weight off for me is being 100% Raw Vegan and exercising daily.
