Does Diet Soda Make You Gain Weight? (Yes, it does)
'In a recent study at Purdue University, rats that were fed saccharin-sweetened yogurt ate more and gained more weight compared to rats that were fed glucose-sweetened yogurt. Some researchers, including those involved with this study, say that this effect translates to humans too, according to a Los Angeles Times article.
These researchers say that no- or low-calorie sweeteners such as saccharin and aspartame signal a sweet taste to the body, without "delivering the goods." The body then cannot properly determine how many calories have been eaten and how many are used up, making weight control difficult.'
