The Claim

In adults with type 2 diabetes following a ketogenic diet, the frequency of hypoglycemia (glucose <70 mg/dL and <54 mg/dL) is not different between those using continuous glucose monitoring and those using blood glucose monitoring.

Description
1 study reviewed
In plain English

Among adults with type 2 diabetes on a ketogenic diet, the number of low blood sugar events does not change based on whether they use a continuous glucose monitor or traditional fingerstick testing.

See the scientific wording

In adults with type 2 diabetes on a ketogenic diet, the frequency of hypoglycemia (glucose <70 mg/dL and <54 mg/dL) remains negligible regardless of whether continuous glucose monitoring or blood glucose monitoring is used.

Why this might work

When someone with type 2 diabetes eats very few carbs, their body doesn't need much insulin to manage blood sugar. Without high insulin levels, the liver doesn't get signaled to stop releasing glucose, so blood sugar stays steady. This means blood sugar rarely drops too low, no matter how often someone checks it.

1 study
  1. Study: 611-P: Effect of Continuous Glucose Monitoring (CGM) vs. Blood Glucose Monitoring (BGM) during a Nutrition Intervention on Time in Range (TIR)

    People with type 2 diabetes on a low-carb diet had very few low blood sugar episodes, no matter if they used a continuous glucose monitor or checked their blood sugar manually. So, the type of monitor didn’t make a difference in causing low blood sugar.
