Diet and exercise may tame hormone Therapy's metabolic side effects in prostate cancer
NCT ID NCT04870515
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tested whether a diet and exercise program could prevent or reduce metabolic side effects like insulin resistance and weight gain in 20 men with prostate cancer receiving hormone therapy and radiation. Participants followed dietary instructions and did aerobic and strength exercises. The study measured changes in insulin resistance, body weight, waist size, and body composition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dietary and exercise intervention
- What this could lead to
- If successful, this approach could help manage weight and insulin resistance caused by hormone therapy, improving quality of life for prostate cancer patients.
- What could go wrong
- This is a very small pilot study with only 20 participants, so results may not apply to everyone. The intervention requires significant lifestyle changes, which may be hard to maintain.
