Overweight Sister

My 16 year old sister is overweight- shes not HUGE but basically if she doesn't do anything about it now shes going to be.
Me, my mum and dad have tried so hard with her, but shes not having any of it. She's tried everything from diets/slimming world/general healthy eating and exercise/personal trainer but she just doesn't put any effort into it and gives up. After that my parents realised maybe she needed space and so let her see if she could do it herself. Suffice to say, she couldn't. Shes ended up putting on at least another stone.
My parents do not have unhealthy foods in the house, and encourage exercise. She attends a stage school where she dances every day (although im not sure how much effort she puts into this)
Basically we're at wits end. We don't know what to do- she uses the 'im happy and fat' excuse but its bull. I can tell it gets her down, and im just concerned for her, her health and her happiness. She's such a bubbly girl and really gets by on her outward confidence and personality but i think she uses being funny etc as a front.
Any time anyone mentions the subject of weight loss she gets angry and rude and doesn't want to talk about it.

Has anyone had any experience with this? and can anyone recommend anything we could try with her?
My mum has considered hypnotherapy as shes obviously a binge/secret eater, and also Fat camp (which personally, sounds quite fun!)

Thanks if you've read this far, any help greatly appreciated!

If you really don't stop doing that to her she could end up with an ED and it's sounds like she's being mentally bullied because of it. You can't honestly say you're concerned for her if you think it would be funny to send her to fat camp - just leave her alone and let her get on with her life.

Stupid media protrayals. Not everyone in the world has to be thin you know.

I don't really understand why you think this a stupid?
Its really difficult when you know someone is unhappy but can't accept help for fear of embarressment.
She is not pressured into doing anything she doesn't want to do shes the one that went on the diets- asked for a personal trainer (i can not tell you how much of a stupid idea this was.) Maybe my post came out wrong. Shes clearly not happy, i can see it. And even if she was, thats no excuse to stand by and watch her slowly get worse.
Most people on here are older than 16, and know that at the age you think you know everything and no-one can tell you what to do.
When i say shes overweight, shes whats classed as obese. She may not look obese to some but she is.
I know this appears a little stupid as a post, and a lot of you seem to be taking the mick which is just pathetic. If you've got nothing nice to say please don't say it at all, I just want the best for my sister. I realise that i've got to be there for her and I am. But I just don't know what else to do.

All you can do is help your sister by maybe joining in, in her dieting regime or going to the gym with her to boose her confidence a little or going swimming together but don't laugh at her situation some people find it extremely hard to cope with the pressures of society.

Thats what I want to do when I'm back from uni. Its just I don't want to seem like im forcing her, because that would just drive her away.
I think it would be fun to gym/swim together, it gets boring alone anyway!
