Steak solution? lean beef may tame blood sugar in teens with PCOS
NCT ID NCT07780188
First seen Aug 21, 2026 · Last updated Aug 21, 2026
Summary
This pilot study tests whether a 12-week diet that includes at least one daily serving of lean beef, as part of a healthy meal plan, can improve blood sugar control in adolescent girls with PCOS. Participants will receive nutrition counseling and free beef, and researchers will measure changes in blood sugar markers and quality of life. The goal is to see if this simple dietary change is both effective and practical for teens.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A 12-week dietary intervention (Beef+) that adds at least one 3-ounce serving of unprocessed, lean beef (less than 10% fat) per day to a healthy meal plan, supported by nutrition counseling and free beef.
- What this could lead to
- If it works, this could offer a simple, food-based way to help teens with PCOS improve blood sugar control and quality of life without medication.
- What could go wrong
- This is a small pilot study, so results may not apply to everyone. The main risk is that adding beef might not improve blood sugar and could affect heart health, though the study monitors safety.
