Summary

This study looks at whether not eating for at least 14 hours overnight (a form of intermittent fasting) is practical and can help improve blood sugar levels in adults who survived childhood cancer. Participants are randomly assigned to either follow this fasting schedule with coaching support or stick to standard healthy eating and exercise advice. The goal is to see if this simple lifestyle change can reduce the risk of diabetes and other metabolic problems common in cancer survivors.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: prolonged overnight fasting
What this could lead to: If successful, this could offer a simple, drug-free way to improve blood sugar control and reduce long-term health risks in childhood cancer survivors.
What could go wrong: This is a small feasibility study, so results may not apply broadly. Fasting for 14 hours nightly may be hard to maintain, and the impact on health outcomes is uncertain.
