The Claim

In adults with type 2 diabetes following a medically supervised very-low-carbohydrate diet with continuous remote care, continuous glucose monitoring provides no additional benefit over blood glucose monitoring in improving time in range (70–180 mg/dL), reducing HbA1c, or promoting weight loss over a 3-month period.

Support is ahead, but a single strong opposing study can change this.

In plain English

For adults with type 2 diabetes on a medically supervised very-low-carbohydrate diet with remote care, using continuous glucose monitoring does not lead to better outcomes in time spent in normal blood glucose range, HbA1c levels, or weight loss compared to standard blood glucose monitoring over three months.

See the scientific wording

In adults with type 2 diabetes following a medically supervised very-low-carbohydrate diet with continuous remote care, continuous glucose monitoring provides no additional benefit over blood glucose monitoring in improving time in range (70–180 mg/dL), reducing HbA1c, or promoting weight loss over a 3-month period.

Why this might work

When people with type 2 diabetes eat very few carbs, their blood sugar doesn't spike as much, so their body doesn't need to react as often to high sugar levels. Whether they check their sugar with a finger prick or a continuous monitor, the low-carb diet itself keeps blood sugar steady enough that extra monitoring doesn't help them do better.

  1. Study: Impact of Continuous Glucose Monitoring Versus Blood Glucose Monitoring to Support a Carbohydrate-Restricted Nutrition Intervention in People with Type 2 Diabetes

    In this study, people with type 2 diabetes ate a low-carb diet and got help remotely, and some used a continuous glucose monitor while others checked their blood sugar manually. Both groups improved just as much in blood sugar control and weight loss — so the fancy monitor didn’t help more than the simple finger-prick test.
