"They measured the weight gain in rats after feeding them yoghurt supplements sweetened with saccharin (an artificial sweetener) or yoghurt sweetened with glucose. The authors found that when the rats were consuming a low-fat “healthy” diet, there was no difference in weight gain between the two groups of rats. But when the rats had a “Western” high-fat, high-sugar diet, the ones being supplemented with artificially sweetened yoghurt put on more weight than the others." "But how could artificial sweeteners encourage over-eating in some circumstances? According to Swithers, artificial sweeteners weaken the normal response of the body to the arrival of glucose in the system. It receives confusing signals: there’s a sweet taste but it’s not accompanied by the usual effects of glucose such as the suppression of hunger mediated by glucose metabolism in the brain or the stimulation of appetite-suppressing hormones from the small bowel. After a period of ingesting sweet-tasting but calorie-free drinks, the body may no longer respond to glucose containing foods with these appropriate appetite-suppressing mechanisms." theconversation/sip-on-this-do-diet-drinks-make-you-fatter-15989
