Clkd,
I do snack on 'good' small snacks if I think my blood sugars low, but just to complicate things, I have had a bad history ( many moons ago) as I think you also may have, with eating disorders.
I am no way like that now, but I know I still see food as good and bad and judge myself on eating habits. I stress I do eat healthy and balanced, but I may still avoid feeling like I eat too much. I am a size 14\16 which is not so bad, and exercise as much as I can, do light weights, but all my life I struggle to lose weight and due to my history I need to do so in a safe and steady way.
I did have some cbt which helped and I am a lot better at accepting myself even if I do also accept I do not have a very good opinion of myself, I do know healthy is better than stupid ways to lose weight, when I did what I did when I was younger, and some of those opinions can remain.
Long answer to your valid advice! X
