The fast track to weight gain...

Some combo meals can pack more than 1,000 calories and 60 grams of fat

Hitting the drive-through every once in a while probably won't lead to a supersize you, but make those cheeseburger runs a habit and you'll see the evidence on the scale. On average, people tend to be about 1.5 pounds heavier for every fast-food meal they eat per week, according to a new study from Temple University. Researchers found that people who ate fast-food meals three to six times a week had a body mass index (BMI) nearly a full point higher than the BMI of people who rarely downed the fatty fare. Ask yourself: Is not having to wash a few dinner dishes worth the extra weight?
