“Although overweight and obese adults who drink diet soda eat a comparable amount of total calories as heavier adults who drink sugary beverages, they consume significantly more calories from solid food at both meals and snacks,” lead study author Sara Bleich, associate professor in the Bloomberg School’s Department of Health Policy and Management, said in a press release.
Researchers looked at information from the 1999-2000 National Health and Nutrition Examination Survey (NHANES), which is a population-based survey that looks at the health and nutrition of U.S. adults. They looked particularly at diet beverage consumption, caloric intake and body weight.
Overall, diet soda consumption rates increased 17 percent from 1965 to today. Currently, about 20 percent of U.S. adults drink diet beverages.
