Can a vegan diet delivered online help people with type 2 diabetes?
NCT ID NCT07095543
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Researchers are testing a 12-week online program that teaches adults with type 2 diabetes and excess weight to follow a low-fat vegan diet. Participants meet weekly with a physician and a registered dietitian for education and support. The team measures body composition, blood sugar control, cholesterol, and food costs at the start and end of the study to see whether the program is practical and whether it changes health markers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a low-fat vegan diet taught through weekly online classes with a physician and dietitian
- What this could lead to
- If the program helps, it could offer a low-cost, remotely delivered way for people with type 2 diabetes and excess weight to improve blood sugar, cholesterol, and body composition through diet.
- What could go wrong
- This is a small, 12-week study without a comparison group, so any changes may reflect effort, season, or normal variation rather than the diet itself. Sticking to a new way of eating is hard, and results may not last or apply to everyone.
