Getting a bit frustrated. Have lost a stone and a half so far but my weight loss has slowed right down. I am doing mfp and eating between 1000 and 1200 a day. I try and keep any treats to under 200 of that. I always do over 10,000 steps a day and do 2-3 workouts a week, but I never eat back any calories. I just wondered if I need to think about changing my diet around.
