HALF THEIR SIZE SPECIAL ISSUE
ON SALE DECEMBER 30

Losing weight is hard enough, but during the holidays—defined roughly as Leftover Halloween Candy for Breakfast Day through The Real Diet Starts Now Day—it's nearly impossible; in fact, during this time, most Americans pack on pounds. No wonder then that the goal of Sissy Lusk—whose journey from 345 lbs. to 123 lbs. was chronicled in the May 30, 2005, issue of PEOPLE—is to "just maintain," she says.

Lusk, 40, has been successful in doing so for four years. That's why, in anticipation of next month's unveiling of our latest crop of weight loss winners who, like Lusk, are now "Half Their Size," we asked her for tips to avoid winter waistline expansion. Among her best advice: Don't cozy up to the buffet. "Circulate. Visit with family and friends," says Lusk, now a Weight Watchers group leader near her Canton, Ga., home. "That's what the holidays are really about."
