Thank you for your responses. She is certainly not obese, just putting on weight, because she snacks between meals. Yes, she obviously likes crisps and chocolate, as do lots of people, but at the same time she realises that these foods are not a good idea. Taking her to the GP is not the answer. Also, she is active and chooses to play various sports and use the gym - these activities are not in any way forced upon her. It has to be handled sensitively, and I know her Mum will deal with it well. I just asked if anyone here had had a similar experience.
