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

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

NIH-funded research Wake Forest University Health Sciences · NIH-10906442

The HALLO-P project is looking at how eating less food or eating only during certain hours can affect the health of older adults, and it will involve a friendly study where some participants will try these diets while others won’t, all with the help of handy mobile tools to keep everyone on track.

What this research studies

The Health Aging & Later-Life Outcomes Planning (HALLO-P) project aims to explore how caloric restriction (CR) and time-restricted feeding (TRF) can impact health outcomes in older adults. This research will involve a multi-site, randomized clinical trial comparing the health effects of CR, TRF, and a control group that does not follow a dietary regimen. The study will utilize mobile health tools to help participants adhere to their assigned diets. A pilot study will enroll 120 older adults to assess the feasibility and effectiveness of these dietary interventions.

Who could benefit from this research

Good fit: Ideal candidates for this research are older adults aged 60 years 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 improved dietary strategies that enhance health and reduce disease risk in older adults.

How similar studies have performed: Previous clinical trials have shown promising results with caloric restriction, but this specific approach comparing CR and TRF in older adults is relatively novel.
