teenage daughter weight!

[Fooso]

Hi all, advice needed. My DSD has a sweet tooth that is out of control. In the last 12 months she has put on about a stone and a half and we think is eating a big chocolate bar a day along with lots of other sugary stuff. She is hiding alot of it in her room. Her dad found more yesterday (she had asked him to help her look for something). We don't know what to do! We don't want to make her feel bad about how much weight she is putting on but she is obviously aware of it (she has stretch marks she hates). She has joined the gym but goes occasionally. She is beautiful and has gone from a size 8 to a 12 since the summer. What do we do? We can't stop her eating can we? Do we just leave it?

How is she getting money to buy this stuff?
I'd not ban sweet stuff but make sure she doesn't have provisions to buy it in that quantity daily imo

she is 17 and is working on a saturday in the hairdressers.. her dad also gives her 40 per month pocket money - how involved should we get?

A size 12 is not very big at all !

She's 17 and a size 12? She's fine.

Make sure there are always plenty of healthy snacks and the odd small chocolate bar around and she might decide it's better to save her money and eat your food instead? Might not work, but might be worth a try. Size 12 is not big generally, but it does depend on the person.

I ate loads of junk food that I bought myself at that age, but I cycled everywhere, so I got away with it.
