How do I not overeat my own cooking?

problem is.. you enjoy food/ eating, and when you make your own, you KNOW how to do it to your liking. Me too. Discipline is the only solution... including dividing your ingredients so there is almost never a 2nd helping. Prepackage things like meat, into single servings, freeze them..then only take out a reasonable amount..

you have to either cook less, or try this. Cook your regular food and have a freezer container on standby. Fix a plate and your boyfriend one, leaving enough for a tiny helping of seconds. Anything more than that, you package immediately and throw in the freezer to keep it away from you and for an easy lunch later.

Start planning to save some of it for lunch the next day.
