Here are more tips from Dawn Jackson Blatner, RD, author of The Flexitarian Diet :
Eat vegetables to help you feel full.
Drink plenty of water.
Get tempting foods out of your home.
Stay busy -- you don't want to eat just because you're bored.
Eat only from a plate, while seated at a table. No grazing in front of the 'fridge.
Don't skip meals.
