Unfortunately, losing weight isn’t always easy. A study reported by the National Institutes of Health suggests that weight gained during the holiday season is never lost. The study also found that the subjects who were already overweight or obese gained more weight during the holidays, five pounds or more compared to one pound for those who were at a healthy weight. Fortunately, the same study also found that participants who reported more physical activity during the holidays were less likely to gain weight and some actually lost weight. So enjoy some healthy activities and avoid gaining weight any time of year.
