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 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.
