Avoid watching TV or movies, that's a huge temptation to eat crappily.
I go to bed and read: I never eat in bed.
Wash up, clean house while listening to good book on Cd, so that my hands are busy and my brain is engaged elsewhere.
Bake, cook; involved projects like making pastry and quiches from scratch, I never eat then.
Brush teeth!
Go to the bathroom and do a facial routine, this takes time and gets me out of the kitchen.
Paint my nails! Can't stick my hand in the box of Frosted flakes then!
Sit and do a pile of mending, hem seams, take up hems, etc, while listening to good book on CD for same reasons as above!
Lots of different strategies...
