A series of studies has reported weight gain in association with COVID‐19 lockdowns; typically, this research has had short‐term follow‐up in populations that tended to gain weight. In this study, the effect of prolonged lockdowns on weight was assessed in a population of patients with chronic obstructive pulmonary disease. Before lockdown subjects gained an average of 0.022 kg per month; after lockdown this trend reversed with subjects losing weight at 0.032 kg per month, a trend that was highly significant (P < 0.001).
