Teenage son secret eating.....

[Endofmyshortfuse]

My DS is 15, tallish, very sturdy build - bordering on overweight.
Toady in his room I have found 2 family size Choc bar wrappers, & an empty box of Lindt Chocs that I was given for Easter. I think he is taking the money from our small change tin & buying th Choc on his way to / from school.
We have had this issue before: we spoke about it. He said he was doiing it because his life was so awful. This turns out to be because we limit his time on screens. Also because he doesn't get to spend time with his friends: they are all lovely but are all real homebodies so don't want to go out. Also we put pressure on him to do his homework..... Other than that his life isn't that awful as far as I can see.
How do I deal with a) the secret eating b) the stealing of food belong to him & c)his feelings?
I'm really worried as he cant afford to get any heavier. & obs I'm worried about him mentally too.
Thanks

I don't know what you can do about that other than give him an allowance and have him not hide it from you. Maybe get him a gym membership? You want him to have a positive relationship with food and his body, telling him he's getting fat might make him eat more out of sadness. He sounds a bit depressed which isn't always totally rational. Maybe cbt would help. I know the do it locally to me on the nhs. Hugs x

Encourage him to exercise, if he’s not into sports then bike rides, or swims
