I was wondering if anyone experiences the same thing i do...

I go through my morning and day and everything is great. No hunger and no cravings and i totally forget about food. then, out of nowhere usually an hour before dinner - BANG - have a little snack and i can't get satisfied. Then, after dinner - BANG - it happens again, i get cravings and again i can't get satisfied with my fats and proteins.

anyone experience this? and what could be the cause? it doesn't happen all the time. I would probably say it happens maybe once a week.
