Not about cravings directly, but what works for me to reduce hunger pangs is to eat a spoonful of any kind of butter or milk fat. It gives me a nice base level of satiety until the next meal.

Anything sugary is only good for 45 minutes at which point the hunger returns in strength.

Now if only I can remember to do this every time.

edit: And no, my weight doesn't increase as a result of the fat-gobbling. It's the sugary stuff that does the damage.
