Weight Loss Programs for Kidney Cancer Prevention

This study is comparing two different weight loss programs, Intermittent Fasting (IF) and Continuous Energy Restriction (CER), for people with small kidney (renal) cancer masses who are under active surveillance (AS). The goal is to see if these programs can help prevent the cancer from getting worse. You could be eligible if you are an English-speaking adult (18+) with a biopsy-confirmed kidney cancer mass, are on active surveillance for less than 5 years, and have a BMI of 25 or higher. The study aims to see how many people participate in each program over 6 months. This study is currently recruiting about 20 participants.
