1-Everytime you want to eat something unhealthy just walk away from that something and wait until you don't want it anymore. Craves only take 5-20 minutes to go away.
2-Drink a lot of water.
3-Use smaller dishes. It will look like you're eating more.
4-Use red dishes because red, to your brain, means "stop".
5-Eat chips or popcorn with the other hand.
8-Don't eat watching tv.
10-Remember that a candy will be in your mouth 2 minutes but much more than that in your stomach.
