- EAT A PRE-PARTY SNACK
Showing up hungry means you'll have little control when surrounded by high-calorie fare, says Leslie Cooperstein, a nutritionist at The Sports Club/L.A. in New York City.
- AVOID ALCOHOL
It contains empty calories (100 in a 4-ounce glass of white wine) and can weaken your resolve to resist treats. Try water instead.
- STEP AWAY FROM THE BANQUET
Standing near the food puts temptation literally in your face. Position yourself across the room and mingle.
- DON'T GIVE IN TO EXCUSES
If you justify poor eating with the line, "But it's the holidays!" you're selling yourself short. "We're surrounded by goodies all year long," says Cooperstein. "If you can eat healthy during the year, you can do it during the holidays, too."
