Summary
Brief summary (as posted)
This research trial studies the effects of diet in patients with a history of melanoma. We are studying the impact of 2 different diets; a whole-foods, fiber-rich diet and a ketogenic diet. Participants will be assigned to one of these diets. During this study, participants will be provided all food at no cost for the entire 6-week study. Food can be picked up or shipped to the participant's home. However, participants will need to come into MD Anderson Cancer Center in Houston, TX, for the initial screening visit and for blood tests every 2 weeks during the study.
