Summary

This study tested whether a 12-week low-carbohydrate diet program, delivered through a smartphone app with remote coaching, could help people with type 2 diabetes improve their blood sugar and lose weight. 115 adults recently diagnosed with type 2 diabetes and who were overweight took part. The program included meal plans, peer support, and activity tracking. Researchers measured changes in blood sugar and weight at 3 months and 1 year.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Low carbohydrate diet
What this could lead to: If it works, this could offer a practical, app-based way for people with type 2 diabetes to improve blood sugar control and possibly achieve remission.
What could go wrong: This is a small, completed trial with only 115 participants. Results may not apply to everyone, and sticking to a low-carb diet long-term can be challenging.
