Feeling guilty about over-indulging over the Thanksgiving holiday? Don't. You may have felt as stuffed as the turkey after your meal (and all the leftovers), but the good news is that holiday weight gain isn’t as bad as you've been led to believe. The truth is that research shows that people, on average, only gain about 1 pound during the holidays. So get back to your healthy eating and exercising till the next holiday gathering ... and get over it!
