It is a tricky issue this, and I am not sure what to do or say to help her. (For the sake of context - I am very overweight - my husband is overweight as well, but not so much.)
Anyway, my daughter is 15 and is a dancer. She spent most of last year off-dance with back pain, which has resolved (mostly) and is now back to an intensive dance schedule.However, she has put on weight - I don't think she is actually overweight, but she is certainly towards the top end of the "normal" weight band. Which is fine. She is a healthy weight for her height.
However, she is constantly surrounded by girls who are much slimmer than her, and it is getting her down a bit. Her father points it out to her to, although I have asked him not to, but he says "if we don't, then she'll end up getting really fat". Which is bollocks, as she already knows she is bigger than the others, and doesn't need anyone to point it out to her. When the subject does come up I tend to point out she is a healthy weight for her height, but that if she wants to lose a bit of weight then I can understand that and will support her. (Obviously a "healthy weight" is a large range, and I suspect she could lose a stone or 2 and still be a healthy weight).
The thing is - I have no idea how to support her in this. I do know what healthy eating looks like, but I am a terrible role model. Added to this she is an extremely fussy eater - if I let her she would live on spaghetti bol, sausage rolls and biscuits. How do you help a 15 year old fussy eater lose weight without dieting as such?
