Summary

This study looked at whether a plant-based diet and lifestyle changes could help people with type 2 diabetes, prediabetes, or obesity improve their health. Researchers aimed for diabetes remission (normal blood sugar without medication for at least 3 months) or significant weight loss. The study enrolled 468 participants and tracked their gut bacteria and health over 2 years.
