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.
