The Study
42-LB: Low-Carbohydrate Diet Compared with Canagliflozin for the Treatment of Diabetes—A Randomized Noninferiority Trial
This study compared two ways to help people with diabetes: eating fewer carbs or taking a medicine. It found that the diet worked just as well, maybe even a little better, in the short term. But it doesn't prove the diet causes these improvements—because people knew which group they were in, which might have changed how they acted.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — lower HbA1c and more stable glucose mean less risk of complications, and cutting meds reduces side effects and costs.
- 2People on low-carb diet lowered HbA1c by 2.23% vs.
- 31.76% on the pill; spent 93.75% of time in safe blood sugar range vs.
- 480.21%; 19% reduced or stopped their meds.

When no carbohydrates are consumed, blood glucose levels decrease and glucagon levels increase.
In adults with type 2 diabetes who are taking medication, following a low-carbohydrate diet for three months led to a 19.2% reduction or complete stoppage of their diabetes medications.
In adults with type 2 diabetes, following a low-carbohydrate diet for three months lowers HbA1c by 2.23%, which is 0.47% more than the reduction seen with canagliflozin, a common diabetes medication.
In adults with type 2 diabetes, a low-carbohydrate diet reduces HbA1c levels by an amount that is not worse than the reduction achieved by canagliflozin over three months, with the difference between the two treatments falling within a predefined acceptable range.
In adults with type 2 diabetes, following a low-carbohydrate diet for three months results in lower spending on antidiabetic medications than taking canagliflozin.
In adults with type 2 diabetes, following a low-carbohydrate diet for three months leads to a higher percentage of time with blood glucose levels within the target range compared to taking canagliflozin.
