I've lost 1.4 stone in the past 6 weeks, going to the gym 4 times a week and eating less calories. It seems to be slowing down in what I'm losing the last 2 weeks, only 1lb a week, but I have been ill this week and last week, and I assume that I will of gained muscle from the gym. Some websites say that you should have cheat meals to stop your metabolism slowing, and also vary how often you are active ie. Gym 3 times one week and 5 the next. What are people's experience in regards to this as I want to lose another 2 stone by Christmas.
