Prolonged Nightly Fasting in Breast Cancer Survivors

Breast Cancer Clinical Trial

Official title: Pilot Study to Assess Prolonged Nightly Fasting in Breast Cancer Survivors

Status Completed

Clinical Trial Summary

This study is being done to examine whether fasting for 13 hours every night is feasible and if it can help breast cancer survivors lose weight and improve their health. - Previous studies have found that women who are overweight or obese when their breast cancer is found (diagnosed) have a greater risk of their breast cancer recurring. Recent research suggests that prolonged nighttime fasting (>13 hours) may improve the risk of recurrence for breast cancer. - This study will examine if fasting for 13 hours per night is doable for participants and will also study what the effect of fasting is on quality of life, mood, fatigue, body size, and markers of health in the blood.
