Using an artificial, no-calorie sweetener rather than sugar may make it tougher, not easier, to lose weight, US researchers said 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 yoghurt sweetened with saccharin went on to consume more calories and put on more weight and body fat The researchers said sweet foods may prompt the body to get ready to take in a lot of calories, but when sweetness in the form of artificial sweeteners is not followed by a large amount of calories, the body gets confused, which may lead to eating more or expending less energy than normal Such an outcome may seem counterintuitive, if not an anathema, to human clinical researchers and health care practitioners who have long recommended the use of low- and no-calorie sweeteners as a means of weight control |
