“It's based on clinical research the YMCA conducted with a big CMS innovation grant where they enrolled 3000 patients into a clinical trial, and they wanted to figure out if a drug called metformin was more effective than just making diet and lifestyle improvements And they found that the diet and lifestyle program was more effective than the drug.”

The claim, plainly

A clinical research trial of 3,000 patients conducted through a CMS innovation grant found that a diet and lifestyle modification program was more effective at diabetes prevention than metformin.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

The claim conflates two related but distinct research efforts. It is true that a landmark clinical trial of roughly 3,000 participants (the 2002 Diabetes Prevention Program trial, N=3,234) demonstrated that intensive diet and lifestyle modification was significantly more effective than metformin at preventing type 2 diabetes (58% risk reduction vs. 31%). However, that trial was funded by the National Institutes of Health (NIH/NIDDK), not through a Centers for Medicare & Medicaid Services (CMS) innovation grant. The CMS Innovation Center grant ($11.88 million awarded in 2012 to the YMCA of the USA) evaluated approximately 3,300 Medicare beneficiaries to test the real-world scalability and cost-effectiveness of the DPP lifestyle curriculum, but it did not include a metformin comparison arm.

The Diabetes Prevention Program Research Group (NEJM, 2002) enrolled 3,234 participants under NIH/NIDDK funding and showed lifestyle intervention reduced diabetes incidence by 58% compared to 31% for metformin.
The CMS Innovation Center (CMMI) awarded an $11.88M Health Care Innovation Award to YMCA of the USA in 2012, evaluating 3,319 Medicare beneficiaries for cost savings and weight loss from the DPP lifestyle intervention without a metformin arm.
