One-Size-Fits-All diet fails? mayo clinic tests custom Weight-Loss plans
NCT ID NCT06770049
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a lifestyle program tailored to a person's specific obesity type helps them lose more weight and keep it off. Researchers at Mayo Clinic will enroll 228 adults with obesity and give them either a standard or a personalized diet and exercise plan for 12 months. The goal is to see if matching the intervention to individual traits leads to better long-term results.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- behavioral intervention (personalized diet and exercise program)
- What this could lead to
- If successful, this could show that tailoring lifestyle advice to a person's specific obesity type leads to more effective and lasting weight loss.
- What could go wrong
- This is a relatively small, early-stage trial (228 participants) testing a behavioral approach, so results may not apply to everyone. Weight loss programs often have high dropout rates and variable success.
