I've had problems with this too, I still do sort of with the occassional lapse but I'm really trying to keep it under control. My strategy was to just drink water when you want to binge, because more often than not when you binge you don't actually feel hungry but you're just craving food. So I just drink water to make me feel bloated and full.
Another strategy I had was just starting the day as late as possible so you can push your meals back, you won't be forced to think about food and wanting to binge when you're sleeping right?
THIS HAS BEEN HUGE FOR ME! I know it's hard to keep track of but I keep a mental tally of how many calories I've eaten so far in the day. I usually like to eat at night or with something in my stomach so I don't go to bed hungry, it makes me sleep a lot better. So I just pull up my mental tally of how many calories I've had during the day along with what kind of physical activities I've had and calculate how many calories I'm allowed to eat at that moment. I've been a big believer in the myth of not eating before bed but from what I've researched online it seems to be just that, a myth. Ever since finding out it does you no better or worse when you eat during the day or how often you eat (all that matters is caloric total), I've been meticulously counting after every meal just to remind myself how much more I can eat for the day. It's hard, it's petty at times, but at the end of the day I feel really happy to know I can still have a little something before bed and I'm still at or under my caloric maitenance for the day!
Empty calories. This kind of flows over from counting calories. Things like soda or pop or any flavored water. I've realized that one can or bottle of soda will contain about 200 calories! I'd much rather use that 200 calories to eat something rather than drink the soda. Plus, this usually adds up since a lot of people drink more than 1 can or bottle so it can add up to 400-600 saved calories for other foods you want to eat if you just drink water instead!
Portion control! That's a HUGE strategy for me at least, after calculating how many calories I'm allowed to eat I ONLY grab that much on my plate. After my plate empties, I'm done! Never grab a whole box of anything or eat in front of the fridge... your self control will be lacking here for sure but if you only have a plate of food in front of you, you're forced to stop after the plate empties.
Wait a few minutes after eating. I read about this for people who ate at buffets, after eating but you still "feel" hungry, wait 10 minutes. I've noticed that food takes about 10 minutes or so to settle in your stomach and more times than not I've felt full after this 10 minutes whereas 10 minutes earlier I felt I could've gorged another plate. Plus, this makes me feel a little confident/happy that I didn't overeat and binge so that's also a motivation to stop as well.
I'm by no means any expert on this stuff but through the years (I've started dieting 3 or 4 years ago) of dieting and trying to maintain my weight, these are the strategies I'd imploy. If any experts feel my strategies aren't healthy or anything of that sort, please post something so you can let me know too! Good luck!
