You need to change your habits, just use stuff like carrots and lettuce/cabbage/broccoli to "stress eat", that will limit the damage.
Someone who "tries" will not succeed, you need to control your impulses and just don't eat shit otherwise you won't make any progress.
Just log everything into mfp, and if you run out of calories in the middle of the day you just don't eat until the next day (and by that I mean breakfast, not 12:01 AM snacks)
That way the behavior will correct itself because you'll automatically gravitate towards low-calorie options.
I've made it a habit to always choose the lowest calorie option of whatever I want and that seems to work out perfectly.
Snacking was a poor choice of words.
What I meant that for me quantity is an important consideration in relation to calory-density, an apple and some beef jerky seems to keep me fuller for longer than say some sort of fatty coconut concoction or "bulletproof coffee".
