NIA funded CALERIE Research Network aims to inspire and support new studies

CALERIE (Comprehensive Assessment of the Long-term Effects of Reducing Intake of Energy) at Duke University has collected a trove of biosamples and data. NIA continues to fund research opportunities using CALERIE data. Caloric restriction (CR) has been shown in laboratory animal models to increase life span. CALERIE was the first study to focus on the effects of sustained CR in humans.
