KIDNEY TRANSPLANTATION, as compared to dialysis, provides longer survival and better quality of life in patients with end-stage kidney disease.1 However, even if the outcomes of kidney transplantation have continued to improve with time,2 long-term survival of kidney transplant recipients (KTRs) is still considerably lower than that of the general population.3 In cohort studies, modifiable risk factors for premature death in KTR include an increase in body weight and obesity,4,5 as well as muscle wasting.
