Overweight teenagers shouldn't mix snacks and television, says University of Rochester nurse Audrey Braunschweig, who works with overweight adolescents.

"People are usually not aware of how much snack food they consume while watching television," says Braunschweig. "Snacking becomes a reflex action based on habit and not on a real need to satisfy hunger."If you get hungry between meals, she says, try fruit or unsalted popcorn. "After your hunger is satisfied, watch TV or, better yet, get some exercise. If you snack while watching TV, the program's over before you know it and the food's gone."
