Joy eats

I have been working on weight loss and have found myself being fearful of planning a joy eat. This is my model:

C: Planned joy eat
T: I am totally going to ruin all that I’ve accomplished
F: Fear
A: Backing out and not following through on joy eat
R: I continue to live in fear of food

I am not a binge eater, but I have a history of not following what I planned, especially with foods that are not in my normal protocol. I know that having one joy eat will not cause me to gain my weight back, but I find myself not planning joy eats because of this fear.
