Because I only ate fruit and vegetable for those 5 days I think my body thought it was going to have to exist for ever on so few calories. That the only explanation I can think of as to why I'm not losing weight right now on xenical, and I've just started taking it again! It's very frustrating. I think I shocked my body too much and now its trying to hang onto every gram of fat. What a mistake I made!
