I have this problem too and in fact have a big issue with food and binge eating. I wouldn't even hazard a guess at the amount of PP I could eat in one sitting. Mine is related to my depression. It could be the same for some of you - perhaps you eat when you feel down? Another one is eating when you're bored (I do this too lol). I'm trying lots of things to curb this at the moment (obviously I sometimes have lapses but I'm generally good at controlling it).
Surround yourself with yummy fresh fruit to snack on.
Keep a bottle of water handy (or some water with sugar free dilute in it to make a tastier drink).
Try some exercise, jogging, walking etc.
Plan your days or your weeks food in advance. If you stick to it 100% reward yourself with something (NOT food though).
Try to choose activities that require you to be unable to use your hands to eat like playing video games, drawing, painting, playing an instrument etc.
If you get the urge when you're bored, do something else nice for yourself. Moisture your skin or paint you nails or pluck your eyebrows... other things that'll take time.
There's lots of things you can try... the first I'd do is plan your day in advance. So plan tonight what you'll eat tomorrow. Maybe even give yourself a nice snack you can look forward to after dinner or mid-afternoon so that you can look forward to your counted treat (rather than a fully fledged binge).
Hope this helps x
