Study of Time Restricted Eating During Chemotherapy in Women with Breast Cancer Stages 1 to 4

What this Trial Is About

Researchers are evaluating the effects of time restricted eating TRE, which involves eating all food within an 8-hour window daily, on women undergoing chemotherapy for breast cancer stages I-IV. The study aims to find out if TRE is feasible and acceptable for these patients and to explore its preliminary effects on treatment outcomes, side effects, quality of life, and fatigue. This research also examines biological markers like glucose regulation, body weight, and inflammatory factors to understand TREs potential impact. Participants will be assigned to either standard care, which follows current nutritional recommendations, or to the 8-hour TRE group. Those in the TRE group will choose an 8-hour eating window starting at 1000 am, 1100 am, or 1200 pm each day and fast for the remaining 16 hours, consuming food without calorie restrictions during the eating window. Calorie-free drinks such as water, black coffee, and diet soda are allowed during fasting. The intervention lasts 24 weeks, comparing three different eating window options to the control group. During the study, participants will be monitored for recruitment feasibility, TRE acceptability, and adherence over 24 weeks. Researchers will assess quality of life, fatigue, treatment side effects, safety through blood counts, and changes in insulin, glucose, body composition, and inflammatory markers. Participants must complete screening evaluations and provide informed consent. The study involves regular assessments throughout the 24-week intervention period.
