For a simple but effective way to manage holiday meals, use the half-off special.
That simply means eat half as much as you normally would or half of what you actually want.
For example, scoop up a bunch of mashed potatoes, then put half of it back.
Picture the amount of dressing or green bean casserole you’d really like, then only take half that much.
Cut a piece of pie in half, then savor and appreciate the flavors. Remind yourself that you’ve gotten what you need from the food, so you don’t need to reach for another piece.
