Obesity is frequent among COVID-19 patients and data indicate that this condition is associated with poor outcomes [1]. Nutritional status, in particular in COVID-19 patients in intensive care unit (ICU), was often assessed by the calculation of body mass index (BMI) classes, allowing to indicate the presence/absence of overweight or obesity [2]. However, scanty information is available on body composition in COVID-19 patients in ICU [2] and, more importantly, on patient's muscularity. In fact, most of the studies conducted in these patients indicate a high prevalence of increased adiposity (based on high visceral adipose tissue by computed tomography - CT) that seems to be able to predict the severity of the disease [3,4].
