'Real' Price of a Bargain Meal

For only 67 extra cents, you can get an overflowing amount of fries, a huge soda pop, and a super-duper burger. (I can say I've eaten fries to excess myself!) But this is no bargain! The effect that it has on your weight and lifestyle is buying more calories that your body can use. It may run you more than 7 bucks in the end. Researchers say that’s what each supersize meal costs, assuming the extra calories turn to fat, which in turn increases the amount of money you spend on food, gas, and medical care to sustain an ever-heavier body.
