I often get cravings when I am nervous/stressed out and this is what I do. I buy those large heads of lettuce. You can get three of them in a pack for 2.99 in Trader Joe's. Then I open the pack put one head on a plate and whenever I get a craving I peel off leaves one by one wash the leaves and eat them. I eat as much lettuce as I feel like, I do not try to hold my self. But I just leave the washed leaves, there's absolutely no dressing allowed. This is great, because peeling and washing each leaf individually satisfies the nervous desire to do something. As somebody else said this cravings are usually mental, they have little to do with you being hungry, but mostly mean you are nervous about something so you need a distraction. And washing leaves one by one before you eat them provides sufficient activity to distract you and relax you a bit. The other great thing about lettuce, is that they are good for you, and yet when you eat them without dressing they effectively provide no calories. The human stomach is not very efficient at breaking down raw greens so eating raw lettuce pretty much takes up as much calories as it gains. So you get necessary fiber and a bunch of other nutrients, but you get no extra calories. And this means that you can eat as much as you would like without feeling any guilt. Also if you eat a lot, you will get a feeling of being full. The feeling will not last for long, but you can use this technique to last you until the time you get a regular meal and can satisfy your hunger with regular food and not junk food.
