How about proposing some lighter recipes around holiday season since the weight you gain may be hard to lose?  Most people only gain about a pound of weight during the holiday season, but that pound may never come off, according to a National Institutes of Health study. University of Missouri dietitians recommend families maintain healthy diet and exercise habits during the holiday season beginning with Thanksgiving.   Cindy Deblauw, registered dietitian and extension associate in the Department of Nutrition and Exercise Physiology, says parents and teachers can help children develop healthy habits by providing them with opportunities to make good choices.
