Although it's commonly asserted that on average people put on about 5 pounds between Thanksgiving and Jan. 1, researchers from Tufts University show that most people add about a pound.
"It's true that parties and a busy schedule can squeeze out exercise and eating well," says Tom Weede, author of "The Entrepreneur Diet: The On-the-Go Plan for Fitness, Weight Loss and Healthy Living." "But you can resist the holiday bulge, and maybe even trim some excess, by tweaking your routine just a little."
-- Before heading to a party or a big meal, eat a toasted whole-wheat bagel or a bowl of oatmeal -- it makes people feel fuller longer.
-- Drink a tall glass of ice water along with your holiday feast -- it leaves less room for eggnog and stuffing.
-- At an all-you-can-eat affair, fill up on vegetables first, then stand or sit a good distance from the table.
-- Take a post-meal walk -- physical activity after a big meal may lower levels of fat in the blood.
