Feasibility and Acceptibility of a Multi-site Trial of Time Restircted Eating During Chemotheraply for Breast Cancer.

Summary

This study is being done to better understand how time restricted eating (eating all food in an 8 hour window) can help a person receiving chemotherapy treatment for breast cancer, stages I-IV. The aim is to find out if time restricted is feasible and acceptable to individuals starting chemotherapy for breast cancer. We will test 3 different eating window options compared to a control group for 24 weeks.
