help im not hungry but im still tryna snack and eat

Go for a walk. Do something to keep your mind off of food Sounds easier than it actually is, but will power is a muscle you need to exercise. Keep at it and you will be able to flex it any time you need to!

Do something to get your mind off of it. I find that I usually have cravings at around 3 or 4 in the afternoon. That's when I go take my daily walk. It helps me twofold; I avoid the temptation and I get moving!

Listen to music.

Ahh, habits and body cycles. The good news is with continued practice, these go away or move to different times around the new way and times you eat.

For the time being, get away from temptation. I signed up to duolingo and when I get these cravings that have nothing to do with hunger, I work on learning German. Anything that either requires deep concentration, or takes up the sound track of thoughts that leads to "I fancy some crisps!" when nothing else is going on, helps.

Go and clean your teeth - you won't want to eat for a while.

Move and keep yourself occupied.

I have this problem too

You said the most important thing. "I'm not hungry". If you know that, then definitely do all the suggestions above. I used to think people were crazy when they suggested going for a walk instead of snacks, but it does work.

My problem is I can fool myself into thinking that I AM actually hungry when I just want to snack and I do get hungry around 3 pm so I have learned to plan something with protein around that time. Eating out of habit is just that, a habit and these can be undone. I hardly ever snack at night after dinner, especially after I log my dinner and see where I am. On a good day, I've planned well enough to have an after dinner treat, so I don't feel deprived.
