The Study
mHealth low carbohydrate dietary intervention ameliorates glycaemic profile, blood pressure and weight status in people with type 2 diabetes
This study shows what happened to a group of people with type 2 diabetes after they used a low-carb app for 3 months. We can see their blood sugar and blood pressure got better, but we can't be sure it was because of the app — other things might have changed too.
Analysis score
Maximum 44 for a cross-sectional study.
Where the score came from
People with type 2 diabetes used a phone app to learn how to eat fewer carbs for 3 months. They felt better, their blood sugar improved, and many needed less medicine.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes, these changes are meaningful—lower blood sugar and blood pressure reduce the risk of heart disease, kidney problems, and other diabetes complications.
- 2Blood sugar (HbA1c) dropped by 1.0%, systolic blood pressure went down by 6 mmHg, and half the people got their blood sugar below the diabetes level.
- 3People who lost 5% or more of their weight did even better.

Claims (6)
Eating fewer carbs might help lower your blood pressure if you have high blood pressure.
If you have type 2 diabetes and use a low-carb diet app for 3 months, your top blood pressure number might drop by about 6 points — which could help your heart — even if you don’t change your exercise or bottom blood pressure number.
If adults with type 2 diabetes eat fewer carbs—dropping from about a third to less than a fifth of their daily calories for three months—they might see their average blood sugar drop by a full point, and the more they cut carbs, the better their blood sugar control tends to get.
If you have type 2 diabetes and use a low-carb diet app for 3 months, there's a good chance—about half the people in the claim—that your blood sugar could get as low as someone without diabetes.
If adults with type 2 diabetes lose 5% or more of their weight in 3 months using a low-carb app, they see better blood sugar control than those who lose less weight.
If adults with type 2 diabetes use a low-carb diet app for 3 months, they end up eating fewer calories without trying, mostly because they eat less carbs — and they naturally replace those carbs with more protein and fat.
