Adult son 22 started off harmlessly joining the gym a year or so ago and we noticed he started going for long runs this wasn't unusual on its own but he'd be constantly checking his steps on his watch all day.
I notice he leaves for work without any breakfast now and I don't know what he eats during the day.
I used to make a packed lunch but he doesn't want that now, again reasonable on its own, he says he prefers to buy something hot as he's on the road a lot with work so could be just that.
He doesn't eat much of the family meal I prepare but he will pick out the meat and then says he's stuffed.
I've always filled the fruit bowl every week and he doesn't touch it and the fridge food remains untouched.
He is so thin his hip bones protrude and his stomach dips in so his jeans don't stay up and all his size Small clothes are hanging off him.
I had brought this up with him but he just says I'm fine mum or I'll have something later and then doesn't.
He stands most of the time and goes up and down on tip toes claiming it's leg exercise and he paces up and down at home constantly monitoring his step count.
He wasn't overweight to begin with he just joined the gym for something to do when he moved back home last year after a relationship ended, this was hard on him and seems to be the starting point and now he has become completely immersed in it and only eats eggs or meat.
He also buys protein shakes which he has before the gym I'm not really clued up on them but dh says they are to enhance performance at the gym.
He honestly ate more when he was 6.
I know he's an adult now and it's up to him what he has but honestly as his mum I'm so worried about this, it sounds like anorexia to me.
Any advice would be very helpful.
