I would say that portioning is super important as well. It is very easy if you don’t have calibrated brain to binge eat huge quantities of food while distracted.

Example you have an extra large bag of chips and you watch a show, likely you will finish before realizing. But if you just put in front of you a small plate of chips, you will likely not stand up to refill it while watching your show.

Add a bit of friction to eating more food. Brains are remarkably lazy.
