Lab study ties artificial sweetener to weight gain

WASHINGTON - Using an artificial, no-calorie sweetener rather than sugar may make it tougher, not easier, to lose weight, U.S. researchers said Sunday. Scientists at Purdue University in West Lafayette, Indiana, studied rats that were fed food with the artificial sweetener saccharin and rats fed food with glucose, a natural sugar. In comparison to rats given yogurt sweetened with glucose, those that ate yogurt sweetened with saccharin went on to consume more calories and put on more weight and body fat.
