Official title: Metabolic Impact and Compliance of Controlled, Varying, Mediterranean Diets in Pre-Surgical Prostate Cancer Populations (PROVISIONS)
Run by University of Miami · NCT06487507 · Data updated 2026-11-12
This study tests whether following a Mediterranean-style diet can improve health and surgery results for men with prostate cancer before they have surgery.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are males aged 18 to 80 with a BMI between 18.5 and 40 who are scheduled for radical prostatectomy.
✕Probably not a fit
Patients currently following a Mediterranean, lower carbohydrate, ketogenic, vegan, vegetarian, or high fiber diet may not benefit from this study.

What this trial studies
This study investigates the effects of a controlled Mediterranean-style diet on fasting insulin levels and other measurable health indicators in men diagnosed with prostate cancer who are scheduled for robotic-assisted radical prostatectomy. Participants will follow either a low fat or lower carbohydrate diet prior to their surgery. Blood and tissue samples will be collected during surgery to assess the metabolic impact of the dietary interventions. The study aims to determine if dietary changes can influence surgical outcomes and overall health in this patient population.
Why it matters
Potential benefit: If successful, this study could lead to dietary recommendations that improve surgical outcomes and metabolic health for prostate cancer patients.
How similar studies have gone: While there is ongoing research into dietary impacts on cancer treatment, this specific approach to a Mediterranean diet in pre-surgical prostate cancer patients is relatively novel.
