Drink lots of water. It's filling and so good for you. And it protects you from grabbing things like eggnog and fruit punch just to whet your whistle. Diet soda is OK, but not as good a choice for overall nutrition as plain old water. Food is a big part of that for most people, but it's not the only thing.
Plan get togethers around activities instead of just around food whenever possible.
If you're getting your holiday enjoyment in MANY ways, it will help put the special foods in perspective. Slow down and enjoy the season. Give yourself some quiet time. Focus on people - whether it's your own family and friends or helping out at the homeless shelter or food bank. Comments and Feedback .
