A Study to Evaluate the Feasibility of Daily, Long-Term, Intermittent Fasting for Men on PSA Surveillance Following Radical Prostatectomy

Overview

About this study

The purpose of this study is to determine whether men treated for localized prostate cancer adhere to a long-term (months-years) daily intermittent fasting regimen, and to measure the levels of metabolic and prostate-cancer derived microparticles in the serum of men that practice a daily intermittent fasting regimen after treatment for localized, high-risk prostate cancer.
