Pella Regional Health Center has released some holiday diet tips. Overeating can be easy around the holidays, whether its a big Christmas Day meal, or a snack table at holiday parties. The big key the dietitians at PRHC stress is moderation. They say to not try to deprive yourself, but to make moderate cuts in your portion size. They also recommend an increase in activity levels before eating a big holiday meal. Overall they say to try to enjoy the family and friends around for the holidays, and not focus on the food.
