Fasting during chemo: a new weapon against breast cancer?
NCT ID NCT07440784
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding intermittent or water-only fasting to standard chemotherapy can improve outcomes for breast cancer patients. Sixty women will be split into four groups: chemo alone, chemo plus intermittent fasting, chemo plus intermittent fasting with a ketogenic diet, or chemo plus a two-week water-only fast. Researchers will measure tumor markers, immune cell counts, inflammation, and quality of life to see if fasting helps the body fight cancer better and handle treatment more easily.
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 (23:1 regimen) and water-only fasting
What this could lead to
If it works, this could point toward a simple, low-cost way to boost chemotherapy effectiveness and reduce side effects for breast cancer patients.
What could go wrong
This is a small, early-phase trial with only 60 participants. Fasting may be hard to stick with, and results may not apply to all patients. It is not a cure.
