Whenever possible, skip the buffet in favor of a sit-down meal, which has the benefit of built-in boundaries. And keep in mind that the dinner table is a place for socializing. Pause to enjoy the company. Research shows that extending a meal gives your body a chance to register fullness before you overeat.
As you're raising a glass of holiday cheer, remember that the disinhibiting effects of alcohol can cause you to eat more. In addition, a glass of red wine has about 125 calories; a cup of eggnog, as many as 340. My gift to you: an eggnog makeover that uses less sugar and replaces whole milk and cream with skim milk. Cheers.
