Summary

This pilot study is testing whether intermittent fasting (with an optional plant-rich diet) is practical and helpful for 30 men with prostate cancer who are receiving hormone therapy (androgen deprivation therapy). The main goal is to see if patients can stick with the diet, not yet to prove it works. Researchers will also look for early signs of tumor response and any side effects.

What this could mean

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

Active substance
intermittent fasting (caloric restriction with optional plant-enriched diet)
What this could lead to
If this approach works, it could point toward a way to improve treatment outcomes and reduce side effects for prostate cancer patients on hormone therapy.
What could go wrong
This is a very small, early pilot study with only 30 participants, focused on feasibility rather than proof of benefit. The diet may be hard to stick with, and results may not apply to all patients.
