Great idea! I'll try it soon, my go-to snack is celery with crunchy peanut butter!
Celery-- fiber, keeps full! "One of the very low calorie herbal plant, celery leaves contain only 16 cal per 100 g weight and lots of non-soluble fiber which when combined with other weight loss regimens may help to reduce body weight and blood cholesterol levels." (http://www.nutrition-and-you.com/celery.html
Peanut butter-- protein, also keeps full! If you're thinking "peanut butter has too much fat", remember that celery is NULL for fat, so the two together makes a snack still healthy on the side of fat AND will keep you full for a long time!
Note: Usually takes 2 pieces of celery cut in half, peanut butter in the center filled as high as the celery is.
I'm sure everyone has heard of this snack, but it's seriously a life-saver for those who feel they are always hungry :3
