Plant-Based diet trial aims to slash diabetes costs
NCT ID NCT05795439
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a low-fat vegan diet and nutrition classes can improve health and lower medical costs for people with type 2 diabetes. Seven hundred Blue Cross Blue Shield subscribers will follow the diet for 16 weeks. Researchers will measure changes in weight, blood sugar, cholesterol, and overall healthcare spending.

- What this could lead to
- If successful, this could show that a plant-based diet helps control type 2 diabetes and reduces healthcare costs.
- What could go wrong
- This is an early-stage behavioral study, not a drug trial. Results depend on participants sticking to the diet, and it may not work for everyone.
