Hi - I just completed week 4. I've already lost over 2 stone with Slimming World and still have about a stone to go, so still definitely overweight. I've been running, doign aerobics and following the same diet that lost me 2 stone but have stuck at the same weight since I started running. I know that at the beginning at least fat is converting to muscle and there can be water retention in the muscle but how long does it take to start actually losing weight? I do feel fitter and leaner but just wish the scales would move! Thanks for any ideas.
