Positive cognitive effects - yes. Very happy feelings when i now eat a small meal and then stop eating. I think my case is somewhat unusual in that my parents pretty much always overrode my "full - stop" signals by saying, "eat some more - what if your hungry later?!" A second helping was the only approval / love i ever got from them. I could never understand my skinny cousins NOT eating.

It wasnt love but it made me terrified to not clean my plate, like even on dates, which sometimes turned out very badly! Not a time you want your lizard (eating) brain taking over!

Ive had to work on accepting and not being afraid of good feelings for DECADES - of fearing some vague retribution, the sense that if i feel good, something bad is sure to happen. Now eating a small bowl of Shredded Wheat and Bran and successfully matching the amount of food to my stomach is a moment of joy. A circuit being closed.
