NiceGuy - yes, it does boil down to calories in versus energy out - but when there are lots of underlying issues (depression, medication, injury etc) you have to tackle the underlying issues first, in my experience. That is what I am trying to explain here.
If you don't tackle why someone overeats, then even if they do manage to lose weight, it won't stay off, because the underlying issues that made them overeat in the first place, will still be there. Tackle the underlying issues, and any weight loss has a far greater chance of being successful.
And as I said, I need to learn to like myself in order to want to take care of myself.
Nijinsky - yes people have mentioned the benefits of exercise, my doctor included, and as you can see from my recent posts on here, I am listening to people's advice about what sorts of exercise to try, and am going to give them a go. I have also had a healthy breakfast for the first time in ages.
