This is total truth. I take very frequent walks (in addition to a rigorous workout routine). Around the holidays, I really step it up - having a fitness tracker really helps with the motivation. After Thanksgiving dinner, I usually walk about five miles. No food coma. On Christmas, I usually walk 10 miles. No food coma. I also pick up little-to-no weight during the holiday season--most of the time I probably lose a pound. I am SURE to eat all I want on the holidays themselves - it's the other days when I am careful!
