I definetely agree with you that in weight loss, the brain is a huge factor. I think it's great you've come so far on your journey that you've achieved the natural appetite control you've been working for. In my case (100 pounds lost, 20-plus added back on, trying to lose 30, lots of issues with healthy eating), I need to continue to actively monitor my food intake (e.g., count calories in a journal). It is too easy for me to eat too much or to let my metabolism and health suffer by eating too little. So if I count calories, I am assured I'm eating enough and that to me is as important in weight control as being sure not to eat too much. Don't know if that makes sense.
Glad you are here. As Punkinseed said, jump on any thread and post away. Good luck on your journey!
