Metabolic adaptation
A high-protein diet increased daily protein intake to 1.6 g/kg body weight and resulted in significantly increased concentrations of two metabolites and reduced concentrations of 98 metabolites compared to baseline.
Practitioners can consider a high-protein diet as a viable option for older adults to enhance metabolic health.
StrongSupportsmedium confidence
The high-protein group increased their daily protein intake to 1.6 g/kg body weight and exhibited significantly increased concentrations of two metabolites and reduced concentrations of 98 metabolites compared to baseline.
Why this rating
Based on the randomized controlled trial design described in the abstract.

- Most metabolite shifts occurred during the dietary intervention phase, with minimal additional changes after resistance training.Strong
- A high-protein diet, alone or combined with resistance training, induces modest but measurable metabolic shifts without disrupting global metabolic homeostasis.Strong
