Italian I've been meaning to post on this thread since I read it months ago...
I know what you mean about it being almost entirely in your head and if you don't address that then the weight loss is unsustainable.
I put on 3 stone last year - I was already in the overweight category - taking me into the morbidly obese category. Admittedly it was a year in which I had to say goodbye to DD, and I was aware over the weeks before and afterwards that I was using food to cope with that but as I was at least not drinking, at less than a year sober, I let it be. And I had two lots of major, immobilising surgery.
So this year one of my two NY resolutions was to lose that 3 stone. I read around a lot and have gone for Low Carb because it really addresses the addictive nature of sugar and why we can't just eat one, and satiety and how we ignore it, etc. (I've joined the threads on here to do it) I've lost 23lb, and I'm still pretty immobile. Exercise plays very little role in weight loss, when it comes down to the science. Vital for our overall wellbeing, but not a big determinant of weight. That was news to me.
It's almost like a second sobriety - because withdrawing sugar (which is what complex carbs are broken down to) means that I am not papering over my feelings, I stop when I'm full, I enjoy my food, and I am moving better, having now got a BMI of 33 (from 37). Prior to the last couple of years, I was maybe overweight with a BMI of 26-28 but nothing like I have put myself through. I don't want to live with the excuses about it and settle my head into thinking that's the way I am.
Anyway, I know you have found a good path for you, and some great ideas, I just wanted to share my path so far this year in the hope it might help someone else.
