Muscle health is crucial for recovery from illness, maintaining independence in aging, and sustaining strength during weight loss, yet it often lacks emphasis in clinical nutrition. A new expert review urges that muscle health should be a primary focus.

This analysis, published in Clinical Nutrition and co-authored by Dr. Nicolaas Deutz from Texas A&M University's Department of Kinesiology and Sport Management, underscores the need to bridge gaps in muscle health discussions within clinical nutrition. The authors suggest that muscle health should not merely be a secondary outcome but a central, measurable target in patient health conversations.
To shift this focus, experts propose redefining muscle health beyond just mass. Dr. Deutz notes that muscle mass alone does not reflect functionality; instead, muscle strength, endurance, and personal assessments of physical capability are equally important. The review broadens the definition to include muscle composition, strength, performance, and metabolic factors, which can vary significantly across different health conditions.
For instance, cancer patients often experience concurrent weight and muscle loss during treatment, while critically ill individuals may face severe muscle deterioration in hospitals. Aging affects muscle mass and function, impacting mobility and independence. During weight loss treatments, preserving lean tissue without losing muscle is critical.
The review suggests that clinical nutrition approaches must become more tailored and detailed, particularly for those who are sick or malnourished. Dr. Deutz highlights that nutritional interventions should go beyond merely increasing calorie intake. Protein intake is vital for muscle maintenance and rebuilding, but the approach needs a comprehensive strategy that considers an individual’s specific condition and recovery stage.
The report calls for a personalized nutrition plan that accounts for variations in metabolism and health status across demographics, including older adults and cancer patients. Additionally, it identifies the preservation of muscle during weight loss, particularly in individuals using GLP-1 medications or undergoing bariatric surgery, as an area requiring further research.
To implement these recommendations into regular clinical practice, standardized measures for assessing muscle health and larger clinical trials are essential. The review advocates for more personalized nutrition strategies and the interplay of nutrition and exercise tailored to various clinical situations.
Dr. Deutz aims to investigate how metabolic changes relate to muscle health, contributing to a broader understanding of individualized nutritional support rather than a one-size-fits-all solution.
