Get off my plate, fat bomb! Indulge at any holiday party without gaining an ounce.

Pigs in a blanket. Potato pancakes. Eggnog.

Who invited them?

You've made it to the third and final week of Vital Juice's Happy Healthidays plan. You're feeling great, losing weight and noshing on delish meals. (Download this week's guilt-free meal plan here.) But now you're facing one of the biggest diet derailers of the season: The holiday buffet. Keri Glassman, MS, RD, shows you how to navigate this diet danger zone.

Going to a bash on an empty stomach? Create a 350-400 calorie supper from a typical party spread. Choose crudité with 1 Tbs. dip (about the size of 1/2 a ping pong ball) or 2 Tbs. hummus (the size of a ping pong ball), two servings of lean protein such as chicken, beef or shrimp skewers, shrimp cocktail or oysters and one mini pizza square or bruschetta. Top it off with one small serving of dessert.

If you've already eaten dinner, nibble on one lean protein from the list above and one dessert. And skip anything wrapped in phyllo dough, such as spanakopita or cheese puffs, mini hot dogs, quesadillas and anything that looks crispy or fried.

Check the extra pounds at the door.
