Summary

This study tests whether a behavioral program — time-restricted eating, nutrition education, and reducing sedentary time — can prevent the unhealthy fat buildup that often occurs during chemotherapy for breast cancer. Researchers will measure changes in visceral and muscle fat using MRI, along with heart and metabolic health markers. The goal is to see if this lifestyle approach can lower the long-term risk of heart disease in breast cancer survivors.
