During the holiday season, we get so used to gulping down goodies that our bodies become virtually addicted to high-calorie fare. "In the six weeks between Thanksgiving and Christmas, most of us derail from our normal diets -- and this can cause our bodies to become accustomed to processing highly caloric foods," says Barbara Crosby, a New York City-based behavioral therapist in nutrition. The result: a wider waistline, lethargy, bloating and cravings. Here, a back-on-track plan to help you rebound fast.

Day 1
Goal: Banish "Bad Food" Cravings!

End overeating for good with these satisfying, study-endorsed slimmers.

Add two eggs to your morning
If you’ve banished eggs from your breakfast menu, you may want to reconsider. A recent Louisiana State University study showed that women who ate two eggs every morning consumed 300 fewer calories a day and lost 65 percent more weight than those who ate a bagel. "Eggs are great day-starters because they’re packed with filling protein, so you feel fuller, longer," says Elizabeth Ward, author of The Pocket Idiot’s Guide to the New Food Pyramids. Worried eggs may up your heart disease risk? Good news: At the end of the study, none of the egg-eating dieters had higher levels of cholesterol or triglyceride -- so start your breakfast sunny-side up!

Pine for pine nuts
These little numbers can reduce appetite by a whopping 60 percent for up to 4 hours, according to a recent report from the Netherlands. Experts believe their polyunsaturated fats boost appetite-suppressing hormones in the brain. But these nuts are naturally high-cal, so a little goes a long way. To get the benefit, simply munch on a teaspoon’s amount daily.
