There has been a lot of hype lately in the media on how low calorie sweeteners may increase the appetite and make you feel hungrier. I know I have patients asking me if that is actually true since low calorie drinks can save you hundreds of calories per day on your calorie count. I have not experienced the increase in appetite and I have been drinking diet sodas for many years. A study recent supported by grants from the National Institutes of Health, the American Beverage Association, and the Corn Refiners Association researched the effect of cane sugar, high fructose corn syrup, lactose and low calorie sweeteners. Study participants were tested daily after they drank one of four beverages and their eating patterns and intake were studied and recorded. The selections were a diet soda, a cane sweetened drink such as iced tea, a high fructose corn syrup soda and a glass of 1% milk, as well as, a control of no beverage at all. Researchers found no differences in how the four caloric beverages affected appetite and food intake. So I would say if you are watching your weight, definitely opt for the lower calorie beverages.
