Research by Susan E. Swithers, a Purdue professor of psychological sciences and a behavioral neuroscientist, shows that diet beverages may not be the healthy choice to manage weight that they appear. Swithers reviewed and evaluated the most recent research on whether consuming high-intensity sweeteners, despite having zero or low calories, may result in overeating, weight gain or other health problems. Her findings were published in Trends in Endocrinology & Metabolism. (Purdue University photo/Mark Simons)
