If you eye a cookie you can easily see how eating a lot of them can contribute to weight gain. Sugary drinks, on the other hand, don't look very fattening. But unlike a cookie, sugar-sweetened beverages don't do much to quell hunger even though they are loaded with calories. In fact, research shows that when people consume rapidly-digested carbohydrates in liquid form rather than in solid form they don't feel full and they don't eat less afterward to compensate for the extra calories, suggests a review by epidemiologists at Harvard School of Public Health.
