This is a Phase 2, randomized two-armed, multi-site study of 138 patients with metastatic castrate sensitive prostate adenocarcinoma. Patients will be randomized 1:1 to receive the fasting mimicking diet, or usual diet. All patients will receive standard of care treatment for their prostate cancer. The fasting mimicking diet will be consumed for 5 days per month for a total of 6 months and will be monitored by trained research dietitians.
This study aims to examine the effects of a fasting mimicking diet (5 days per month eating L-Nutra products only for 6 months) vs. usual diet on response to cancer treatment of metastatic castrate sensitive prostate adenocarcinoma.
