18stone 18 year old gs

Don't now much about it but the NHS has a weight loss 12 week plan. You can sign up online (so "secret") and they have help and advice, and I THINK support if you want it.
If he uses the computer this might be ok to start him off - as in some ways it's familiar territory and he can be anonymous.

Also, if quite a bit overweight, he should lose the first few pounds fairly easily which will give him confidence and might encourage him to continue.
Maybe his father could check it out ahead of suggesting it....
Good luck.

Self esteem is a tricky thing - my youngest daughter is liable to put on weight VERY easily - a weekend away with friends, parties or a stressful/late week at work (leading to take-away dinners) might be all it takes. Now, at 26, she knows just what to do to put it right, and also how much better she feels when she's a bit slimmer. She doesn't actually "yo-yo" - just feels her jeans getting tighter - and then sorts it out. She just knows that she is SO much happier when her clothes fit well and that she has to act accordingly if she doesn't want to be miserable.

I know this doesn't sound much fun, but she is a happier and more confident person now than she has been since a teenager - and, as she says, she eats well and sensibly mostly, and when she doesn't, that's her choice.
I wish your family well and hope your grandson finds a way through.

Thank you all for your support. I'm hoping that getting merit star in a couple of btecs will give him a boost, and suggested to my son that he consider asking my gs to come and live with him for a while as gs has now left school and only has an occasional job at weekends. Son said he had already thought of suggesting it. Son could do with losing a few pounds and they could support each other in an area where gs is incognito. Hope it happens.

HI Nicky What a worry for you and your son,I suggest trying to get your GS to go with his dad to see his GP where there is a programme run from most Surgeries for healthy eating advice they run for about 12 weeks and some even give free admission to sports halls/swimming baths etc and whilst there he may meet some new friends,I wouldn't try to say I'd pay him for every half stone he loses,but say when he reaches a reasonable target weight you will take him out and treat him to a new wardrobe of clothes. best of luck

You may find that there is a weight loss clinic at the local hospital, or even the GP - he needs someone alongside him to help him. Once you get that big, you stop caring and eat for comfort. What a worry for you.
