Hi been out of the gym for 7 weeks with health reasons lost half a stone from not eating rite and not training. Need some advice on how to get my apitite back. I did way 9 stone this time last year I'm now a 11 and 1/2 I know half a stone is not a lot to lose but I don't want to slip back to that skinny me again and I'm finding it hard to eat as much as I did
