There are 3 ways you can stop overeating at Thanksgiving or Christmas. 1: Use a smaller plate - and fill half your plate with protein, and half with non-starchy vegetables. Eat slowly and enjoy every single bite. 2: Never go back for seconds - make a rule and stick to it. 3: Choose your splurge - you might want to enjoy one of your family's favorite recipes such as garlic bread, bread stuffing, or a special dessert, just don't eat all of them. Pick one, and one only.
