Abstract We assessed physical activity using accelerometers and a questionnaire in 33 post-bariatric patients who reported to be adherent (n = 15) or not (n = 18) to social distancing due to the COVID-19 pandemic. Patients adherent to social distancing spent more time in sedentary behavior (1.1 h/day, 0.1, 2.2; p = 0.045) and less time in moderate-to-vigorous physical activity (− 12.2 min/ day, − 23.8, − 0.6; p = 0.040) vs. non-adherent ones. Bland-Altman analysis comparing objective and subjective physical activity estimates showed a bias for time spent in sedentary behavior and moderate-to-vigorous activity of 2.8 h/day and 8.5 min/day. In conclusion, post-bariatric patients who were adherent to social distancing measures were more inactive and sedentary than nonadherent ones. Strategies to increase physical activity in post-bariatric patients exposed to social distancing are necessary during the COVID-19 pandemic. Keywords Moderate-to-vigorous physical activity . Sedentary behavior . Severe obesity

Introduction Bariatric surgery is an effective treatment for severe obesity, resulting in substantial weight loss, remission of type 2 diabetes, and improved overall cardiometabolic profile [1]. Weight loss often peaks 1 year following bariatric surgery, and then it is commonly followed by a partial and gradual weight regain

after 2 years [1]. However, when physical activity is increased during the post-surgery period, patients may exhibit a superior initial weight loss and long-term weight maintenance, which is paralleled by sustained improvements in cardiometabolic health [1]. Despite the acknowledged benefits of increasing physical activity in the post-surgery period, most patients remain physically inactive and sedentary [2]. As of March 24, 2020, Sao Paulo government adopted a set of social di
