Whole-Food Plant-Based Diet to Control Weight and MetaboInflammation in Overweight/Obese Men With Prostate Cancer

Pre-packaged, freshly made plant-based meals (provided by either Plantable or CookUnity) will be delivered weekly to participants' homes for 8 weeks. Meals are made with whole ingredients including whole grains, vegetables, legumes, nuts and seeds. Added sugar, animal-based products, refined grains, and processed foods are not used in any meal. Participants will be coached via phone calls, SMS, emails, and the app throughout the intervention to prepare meals in accordance with the diet. Participants will have access to a Registered Dietitian. During the first 4 weeks, 12 meals/week will be provided to participants; followed by 6 meals/week for the next 4 weeks; followed by 18 weeks where participants will continue to receive coaching, but will be expected to make all their own whole-food, plant-based meals with staff assistance available.
