My mum is a Slimming World member and recently got her 2.5 stone award, but she is really struggling at the moment and I don't know how to help her. Her weight loss has slowed down a lot recently and she had a 3.5 pound gain in the last week. She is definitely following the plan, plus she has very few syns and gets loads of exercise (up to 3 hours every day). Neither of us can understand where the weight has come from. She is becoming very depressed and I'm worried she might do something drastic. Is there any advice I can give her?
