Thanksgiving marks the beginning of pretty much the most festive season on the American calendar. With Christmas and New Years following close behind--and the abundance of celebratory drinks, dinners and sweet treats mandatory for these holidays--the months of November and December can be quite fattening.

If you're looking to have a healthier Thanksgiving than years gone by, and you'd like the only stuffing to be the kind in your turkey, make sure your menu includes a few guilt-free Thanksgiving desserts.
