With all of the tasty treats on the holiday table, it's hard not to give in and eat a week's worth of calories in one sitting. There's no sense in depriving yourself from enjoying your favorite foods. Pick the ones you want to indulge in, but limit yourself to one serving. Once you're done, put the rest in a container and slide it in the fridge. You'll be less likely to dig in for seconds when the food is already put away.
