The New York Times provides the details of the study, which included 36 overweight and obese adults who watched at least three hours of TV a day. Twenty individuals agreed to cut their TV-watching in half, and researchers measured their movements remotely.
On average, these participants "spent more time in light physical activities or sedentary activities that burn more calories than watching television does--reading, playing board games, or scrapbooking," according to the Times article. As a result, they burned 120 more calories per day than others in the study.
Although burning an extra 120 calories per day isn't enough for serious weight loss, it does add up over time. If you're looking for an easy first step toward better health, why not start by getting off the couch?
So, how much time do you normally spend in front of the television?
