Investigating the effects of caloric restriction and time-restricted feeding on health in older adults

Health Aging & Later-Life Outcomes - pilot (HALLO-P)

NIH-funded research Wake Forest University Health Sciences · NIH-11146215

This study is looking at how eating less food and timing meals can help older adults stay healthier and reduce the risk of diseases, and it’s for people aged 60 and up who want to explore these dietary changes.

What this research studies

The Health, Aging and Later-Life Outcomes Planning Grant (HALLO-P) aims to explore how caloric restriction and time-restricted feeding can impact health outcomes in older adults. This research will involve a pilot study with 120 participants aged 60 and older, focusing on the feasibility of these dietary interventions and their effects on disease and disability risk. Participants will be randomly assigned to different dietary regimens, and innovative mobile health tools will be used to help them adhere to the protocols. The ultimate goal is to design a larger clinical trial that can definitively assess the benefits of these dietary approaches.

Who could benefit from this research

Good fit: Ideal candidates for this research are older adults aged 60 and above, particularly those with a BMI of 27 kg/m2 or higher.

Not a fit: Patients who are younger than 60 years or have a BMI below 27 kg/m2 may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to effective dietary strategies that improve health and reduce disease risk in older adults.

How similar studies have performed: Previous clinical trials on caloric restriction have shown promising results, indicating that this approach may be beneficial, but the specific application of time-restricted feeding in this context is relatively novel.
