This study reviewed the effects of high-protein supplementation in cancer patients undergoing therapy, focusing on clinical outcomes like body weight, muscle mass, strength, and quality of life. The results showed that high-protein supplementation mitigated weight loss, improved muscle strength, and reduced hospitalization rates. No significant improvements in health-related quality of life were observed. The findings suggest that high-protein supplementation may be beneficial but warrant further investigation due to variability in study quality.
