Metabolic adaptation
A high-protein diet, alone or combined with resistance training, induces modest but measurable metabolic shifts without disrupting global metabolic homeostasis.
Older adults can safely increase protein intake without adverse metabolic effects, especially when combined with exercise.
StrongSupportsmedium confidence
These findings suggest that older adults can adapt to elevated protein intake while maintaining metabolic stability, supporting the metabolic safety of a high-protein diet in combination with resistance exercise.
Why this rating
Based on the randomized controlled trial design described in the abstract.
