Many people find that using a low-carb diet (like the Atkin's Diet) cuts the appetite. I found it to work for me - lost about 45# in 5 months.
Some great ways to distract yourself from hunger are:
Paint your nails- then you'll be reluctant to ruin your nails by eating
Eat a mint or chew gum- this works well because the mint taste makes most foods taste bad
Smelling peppermint can sometimes deter hunger
I don't understand your question. What do you mean by "destruct yourself from the hunger"? Do you mean "protect", rather than destruct?
