2. You don't need to eat everything that is brought to the party. If there are 3 kinds of potatoes, choose a small portion of one - or select 1 or 2 bite size servings of each if you must have a taste (my mother called this a "no thank you" serving when I was a kid, but it's a great strategy to avoid overflowing your plate and eating too much.) Don't feel obligated to eat everything that is put out just because it is a classic holiday food.
3. Keep it colorful. If your plate consists of only white food (turkey, stuffing, mashed potatoes, rolls, etc.), add a nutrient boost by including some color - such as a salad, green beans, or try going for the sweet potato instead.
4. Watch the cocktails. Many holiday drinks are loaded with sugar and added 'flavoring'. If you must indulge, limit yourself to one. It is also a good strategy to drink a glass of water between your other drink of choice to stay hydrated.
5. Create a pre-party strategy. If you know the food will be heavy and not in line with your healthy eating habits, have a small meal before you go so that you can enjoy yourself. If you are tempted to overindulge, have your partner or friend be your buddy - you can share the dessert and keep each other in check.
Most importantly, have a happy holiday season!
