Changing Thoughts About Being Thin

I’m realizing after listening to a lot of Brooke’s goodness, that I still didn’t reach my ideal weight as I still think like a fat person. I need your help!

original model

C just ate lunch
T no meal can end without something sweet
F urge
A eat chocolate
R stay fat/gain weight, keep on struggling

How would a permanently slim person think?
C eat planned lunch, no dessert
T that’s all I need
F at peace
A eat on protocol, no sweets
R lose weight/keep weight on low level

Is that T “enough”? It feels a bit weak. Any ideas? And: How do I practice that “future model”? Thank you!
