Eat Healthy If there’s ever a time to indulge in a few extra sweets and appetizers, the holidays are it. And you definitely shouldn’t deprive yourself—that is depressing! However, if you start letting nutrition slide because you’re eating on the go or fill up on the endless supply of Christmas cookies at the office, your mood and your waistline will suffer. Make a point of eating healthy meals throughout the day and only treat yourself after you’ve replenished your energy supply.
