Is it really healthy to restrict protein intake for kidney transplant recipients?

A recent study published in Clinical Nutrition found that sufficient protein intake is necessary to prevent sarcopenia after kidney transplantation. The research showed a positive correlation between changes in skeletal muscle mass and protein intake, with insufficient protein intake resulting in decreased muscle mass.
