Abstract

Triple-negative breast cancer (TNBC) is highly glycolytic and lacks effective biomarkers for therapy response. The BREAKFAST trial showed that a fasting-mimicking diet (FMD) improved pathological complete response (pCR) rates to 56.6% compared to historical chemotherapy averages (30%-40%), with minimal severe adverse events. FMD's metabolic and immune-modulating effects warrant further study with immunotherapy.
