Buy smaller Tupperware or take-away containers to pack meals. If you typically pack a meal, make sure to use smaller Tupperware as well.When you're eating, try to remove extra temptations from the table. This can help you focus on your meal only and decrease the chance you'll eat more than you should. Don't bring bowls or platters of food to the table when you're able. This may tempt you to serve yourself seconds.
