Calorie reduction to help the immune system fight cancer

Dietary regulation of anti-tumor immunity through caloric restriction

NIH-funded research Van Andel Research Institute · NIH-11304546

This project looks at whether eating fewer calories and increasing ketone availability helps immune T cells better fight tumors in people with cancer.

What this research studies

Researchers will reduce calorie intake (about 30–50%) and study how that changes nutrients in the tumor environment, focusing on ketone bodies versus fatty acids. They will track how these changes steer CD8 T cells between active tumor-killing and exhausted states using animal models, cellular experiments, and molecular analyses. The work examines epigenetic, transcriptional, and metabolic programs in T cells and tests whether the ability of T cells to use ketones is required for the anti-tumor effect. Findings aim to reveal diet-regulated mechanisms that could guide future dietary or drug approaches to boost anti-tumor immunity.

Who could benefit from this research

Good fit: People with solid tumors who are open to dietary interventions or who are receiving immune-based cancer treatments would be the most relevant candidates.

Not a fit: Patients with cancers that do not rely on immune responses, or those who cannot safely reduce calorie intake, may not benefit from this approach.

Why it matters

Potential benefit: If successful, this work could lead to dietary strategies or new therapies that strengthen T cell responses to help control tumors.

How similar studies have performed: Prior animal and early clinical work suggests calorie restriction or ketogenic approaches can slow tumor growth and alter immunity, but the specific role of ketone metabolism in CD8 T cells is a newer, still-emerging finding.
