Most food advice is aimed at the food. What to eat, how much, in what combination. I use a different measure, and it has nothing to do with the food itself.
Do you feel bad about it afterward?
Not a vague sense of having failed. Specifically: when it was done, later on, did you feel bad, or did you not? If you genuinely did not, it was probably fine, whatever it was. If there was hesitation, guilt, that quiet wondering whether you should have, then something else was going on underneath, no matter what the food was or how much of it there was. This is what I call Guilty Residue.
Here’s an image I use to make this concrete. A grandmother takes one bite of birthday cake because her grandchild wanted to share the moment with her. She takes the bite, and it’s enough. Full presence, no background negotiation, no guilt on the other side. That’s what a genuinely joyful experience with food looks like.
Now picture eating something while standing at the counter, half tasting it, aware somewhere in the back of your mind that this isn’t really what you wanted. The food could be identical. What’s happening underneath it is not.
It’s not black and white. Treating it that way is what causes the painful part, the swing between rigid rules and giving up on them entirely. The guilt barometer doesn’t ask you to be perfect. It just asks you to notice, afterward, how you actually feel. That’s more useful than any rule I could hand you.
