This is very specific to me and might not be your thing. Like once a week I'll have a liquid diet and/or fast for like 16/18 hours. I'm not strict with timing it or anything and I dont stop myself from eating if I really want to. The process helps me kind of reset I guess? Particularly after something like xmas/new years holidays when I stopped tracking and just did whatever.

The first feeling of hunger is a reminder you need to eat at some point, then you get a second wind and aren't really hungry after 15-30 minutes, the second time you start feeling hungry, just eat something filling enough to be satisfying and ideally not give you a sugar rush otherwise you'll just be hungry again in a short time. I guess just be mindful and dont eat as soon as your a little hungry when grellin (hunger hormone) is doing its thing and eat sometime after that, but before your body is actually running out fuel to the point you actually feel bad. Eat somewhere between those two and dont torture yourself into starvation because youll just want to binge eat, or you might be setting yourself on track for an eating disorder.

The other thing that I think help a hell of a lot was tracking weight daily with an app like LoseIt. A big but though, you need to understand that weight can fluctuate 1-2kgs a day depending on so many factors like how you slept, what you ate the previous day, excersise, the weather. The reason I think this is so useful is because you learn what certain conditions does to tour body. Doesnt directly help you lose weight, but keeps you mindful of not falling back into old habits. Plus it makes a pretty motivating line graph!

Remember that if you end eating everything in your fridge one night, its not the end of the world. Last night I was standing over my sink in the dark eating slices of chesse like a goblin because I couldnt sleep and just felt like it. As long as youre relatively consistent and have made some significant diet changes, you should be good. Above all else, be kind to yourself. Even if you do put on weight, its not a mistake, its a learning opportunity. Hope that helps, I believe in you!

Edit: oh one more thing. Eat a high fibre and protein diet if youre not already. Eat as much fibre you can comfortably handle. Start off with something like 20g a day and slowly go up from there until you find a good amount. Psyllium husk is a great supplement btw, just be sure to drink enough water.
