The Claim

In adults with type 2 diabetes, consuming a very-low-carbohydrate, high-fat breakfast reduces postprandial glucose spikes after breakfast by more than 50% compared to a standard-carbohydrate breakfast, and breakfast is the most impactful meal for glucose control in this population.

Source: Restricting carbohydrates at breakfast is sufficient to reduce 24-hour exposure to postprandial hyperglycemia and improve glycemic variability.

In plain English

If you have type 2 diabetes, eating a breakfast low in carbs and high in fat can cut your blood sugar spike after eating by more than half—better than a normal breakfast—and this meal might be the most important one for keeping your blood sugar under control.
