Well I am not sure what type of diet you are talking about. I usually do the Celebrity Juice diet. You basicly drink juice for 48 hours and water. You are allowed six 8oz glasses of the juice and as much water as you need. I usually loose 8-10lbs on it and it will clean you out pretty good. Bad thing is, the weight comes right back since it's all water but if you are just looking at cleaning your body out then it would work for that purpose really well.
