Study Background: Whole-foods, fiber-rich diet rationale: Recent studies have shown that the gut microbiome (the trillions of bacteria that live in our intestines) can influence our immune system function. Diet plays a key role in shaping the gut microbiome. We will examine the effects of a whole-food, fiber-rich diet on the gut microbiome within patients with a history of melanoma. Ketogenic diet rationale: The ketogenic diet is a very-low-carbohydrate, high-fat diet. The goal of this diet is to change the body's fuel source from carbohydrates to fat and to lower levels of insulin. We will examine the effects of a ketogenic diet to change metabolism within patients with a history of melanoma. Who can participate? To be eligible for the study, participants must meet the following criteria: Be at least 18 years old; Meet the study requirements for Body Mass Index (BMI); Have had melanoma within the last 5 years; Be cancer-free at the start of the trial; Have not received systemic therapy within the last year; and Have no medical issues that would make them unable to follow these eating plans. Study Design: Our study will enroll up to 10 participants to each diet (high-fiber or ketogenic). After screening, participants will have baseline assessment performed that will include collecting diet information, blood and fecal samples, and body composition information. Participants will then eat the provided diets for the next 6 weeks while coming in every 2 weeks for blood and stool specimen collection. Six (6)weeks after the diet intervention is complete, participants will come back to MD Anderson for one last end of study visit. Who makes the meals?: All calorie-containing food and beverages will be provided by either the MD Anderson Cancer Center Bionutrition Research Core or Savor Health (a third-party vendor contracted by MD Anderson). Costs: There will be no cost to participate in this study. Benefits: All food and beverages you will eat as part of this study will be provided by the study and can be shipped directly to your home. The results will be used to help us design future dietary intervention trials in Melanoma patients receiving immunotherapy. Please note, participants can withdraw from the study at any time without consequences.
