Haven't you always suspected as much?
Consuming low-calorie drinks may increase the risk of putting on weight, according to scientists in the United States.
They have suggested that people who choose diet drinks containing artificial sweeteners tend to overcompensate and consume more calories than those who do not.
Although the rise in obesity has corresponded with a growth in low-calorie soft drinks, designed to make keeping weight down easy by replacing sugar with saccharine or other sweeteners, scientists who conducted experiments using rats at Purdue University, in Indiana, have suggested that the opposite may be happening.
I suppose the next thing they'll tell us is that restaurant calories do count. And a walk around the block does not equal two extra doughnuts.
