(HealthDay)—It's the dieter's tug-of-war: the need to lose weight versus the urge to eat high-calorie foods.

Scientists say the easy availability of sweets and other treats has made the desire for them stronger over time. Couple that with a that burns fewer and fewer calories, and battling the bulge is that much harder.

To win the war, your dieting strategy has to include a way to manage food urges, especially when eating for reasons other than hunger.
