Does a fancy glucose monitor help more than a finger prick when you're eating keto?

Consuming carbohydrates raises blood sugar, which can cause sugars to attach to proteins in cells, triggering widespread inflammation in the body.

For adults with type 2 diabetes, using a continuous glucose monitor does not lead to better blood sugar control than using traditional blood glucose testing, when both groups are following a ketogenic diet and receiving remote care.

For adults with type 2 diabetes, following a ketogenic diet under medical supervision along with remote care helps maintain blood sugar levels within a healthy range more consistently, whether they use a continuous glucose monitor or traditional fingerstick testing.

For adults with type 2 diabetes on a medically supervised ketogenic diet, using either continuous glucose monitoring or traditional blood glucose monitoring is linked to measurable improvements in the amount of time their blood sugar stays within a healthy range, with continuous monitoring showing a slightly larger average improvement over three months.

In adults with type 2 diabetes on a ketogenic diet managed remotely, using continuous glucose monitoring does not change overall time spent in the target glucose range compared to traditional blood glucose testing, but it is associated with a higher chance of meeting stricter glucose targets, such as spending more than 70% of the time in range and less than 4% of the time below 70 mg/dL.
