Since the Master-Cleanse is as the name implies a "cleanse" the body will do what it needs to do the most first to heal itself and sometimes is not necessarily related to weight loss. I only lost 20 lbs on my 40 day MC. I've heard of folks loosing almost no weight at all on a 10 day MC. The biggest and fastest weight loss will happen at the beginning when you empty your bowels. I've been around this forum around 3 years on and off and I have never heard of anyone losing 2 pounds a day steadily throughout the MC
