How to Survive Holiday Season without Gaining Weight

That's often enough to make sure you stay on track, but not so often that you take all the fun out of holiday noshing, says Michael Dansinger, MD, an assistant professor at Tufts University School of Medicine. Step on the scale first thing in the morning when your stomach is empty.

Eating slowly may not be easy when appetizer options are endless, but it pays off to pace yourself. The quicker we eat, the less time the body has to register fullness. So slow down and take a second to savor each bite of baked brie or scoop of spiced nuts.

Grab a bag while on the go or at work. Make a pact with yourself that you’ll eat your five-a-day before you snack on any cookies or other holiday treats.
