Mayo Clinic Health SystemAre You Getting Enough Protein?

This consumer health article provides evidence-based guidelines for protein intake across different population segments. The content addresses common misconceptions about protein requirements and offers practical recommendations that clinicians can integrate into patient counseling for nutritional management.

Key Clinical Considerations

• Protein requirements vary significantly based on age, activity level, and health status, with recommended intake ranging from 0.8 g/kg for sedentary adults to 1.7 g/kg for athletes.
• Adults over age 40-50 require increased protein intake (1-1.2 g/kg) to combat sarcopenia, supporting the clinical importance of age-adjusted nutritional counseling.
• Timing and distribution of protein consumption throughout the day impacts effectiveness, with evidence suggesting 15-30g per meal is optimal for utilization.
• Weight loss medications and caloric restriction create risk for inadequate protein intake, potentially accelerating muscle mass loss instead of targeted fat reduction.
• Excess protein intake (>2 g/kg) offers no additional benefits and may increase cardiovascular risk through elevated blood lipids, particularly when protein sources are high in saturated fat.

Clinical Practice Impact

• When counseling patients on nutrition, clinicians should incorporate protein assessment as part of standard care, especially for those using weight-loss medications, adults over 40, and physically active individuals.
• Patient education should emphasize whole food protein sources distributed across meals rather than supplements or concentrated evening consumption.
• Consider developing a standardized screening approach to identify patients at risk for both inadequate and excessive protein intake, as either extreme presents distinct clinical risks.
