Paradox of Diet Sweeteners

Believe it or not diet sodas will make you fatter. Researchers at Purdue University gave rats set amounts of yogurt sweetened with either sucrose of saccharin plus an unrestricted supply of ordinary rat food and water. Five weeks later, the saccharin-fed rats had eaten more food, gained more weight and put on more body fat than the others. They also found that giving the sucrose-fed rats a high calorie chocolate pudding treat made them eat less afterwards, whereas the saccharin trained rats showed less restrain in what they ate next. The researchers concluded that animals, including humans use cues like sweetness to predict satiation. When the relationship between sweetness and calories is consistent, they unconsciously use it to regulate intake; when it’s inconsistent, they can’t.
