The National Institute on Aging (NIA) invites applications for research projects (R01) involving secondary analyses of data in the Computerized Tracking System (CTS) database from the CALERIE (Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy) trial to explore behavioral and
psychosocial aspects of sustained caloric restriction (CR) in humans, including the translation of the CR adherence strategies used in the trial to promote healthy behaviors, especially for the prevention of weight gain with age.
CALERIE was the first trial in humans to specifically focus on the effects of sustained CR.
It demonstrated feasibility of sustained human CR (for at least two years) and favorable effects on predictors of longevity, as well as on cardiometabolic risk factors.
The sustained weight loss in CALERIE has not been previously attained in any clinical study in non-obese individuals.
