Caloric restriction in older adults with obesity: aging markers, frailty, and healthspan
Official title: Effect of caloric restriction on aging biomarkers, frailty, and multimorbidity in older adults
Funded at Wake Forest University Health Sciences · NIH-11366484 · Data updated 2026-11-12
Aging adults who are obese may benefit from a carefully controlled reduction in calories to see if it improves aging biomarkers and overall health.

Who could benefit from this research
✓Could help
Older adults with obesity who are able to participate in supervised caloric restriction.
✕Less likely to help
Individuals unable to safely restrict calories or who do not experience aging-related biomarker changes.
What this research studies
This project tests whether short-term caloric restriction can positively affect biological aging markers and frailty in older adults with obesity. Researchers will monitor physical function, metabolic health, and aging-related biomarkers to understand potential healthspan benefits. The study is designed to connect biological aging signals with real-world health outcomes in a group at risk for obesity-related decline.
Why it matters
Potential benefit: If successful, the approach could lead to healthier aging and fewer age-related health problems for older adults with obesity.
How similar studies have gone: Previous short-term trials show some metabolic and functional improvements, but long-term aging benefits in humans remain uncertain.
