...series of experiments, scientists at Purdue University compared weight gain and eating habits in rats whose diets were supplemented with sweetened food containing either zero-calorie saccharin or sugar. The report, published in Behavioral Neuroscience, presents some counterintuitive findings: Animals fed with artificially sweetened yogurt over a two-week period consumed more calories and gained more weight - mostly in the form of fat - than animals eating yogurt flavored with glucose, a natural, high-calorie sweetener. It's a continuation of work the Purdue group began in 2004, when they reported that animals consuming saccharin-sweetened liquids and snacks tended...
...sweetness and calorie link - the animal tends to eat more and gain more weight, the new study shows. The study was even able to document at the physiological level that animals given artificial sweeteners responded differently to their food than those eating high-calorie sweetened foods. The sugar-fed rats, for example, showed the expected uptick in core body temperature at mealtime, corresponding to their anticipation of a bolus of calories that they would need to start burning off - a sort of metabolic revving of the energy engines. The saccharin-fed animals, on the other hand, showed no such rise...
