The holiday season is a time of festivities, family, fun — and, often, feasting. For many, it’s tough to resist the seemingly endless supply of delicious dishes, from mashed potatoes and green bean casserole to Christmas cookies and pecan pie. When it comes to warding off winter weight gain, many people try to fix the damage after it’s done. But can you really “undo” overeating by slogging on a treadmill the next day?

The holiday party season can be a mixed experience for those trying to manage their weight. While it's a cheerful time filled with opportunities to connect with friends, colleagues, and loved ones, holiday gatherings often come with tempting treats that can lead to feelings of guilt if you overindulge. On the other hand, if you don't allow yourself any leeway, you might feel deprived, which can create unnecessary anxiety during this festive season.
