The Claim

Intermittent fasting reduces blood glucose levels and improves insulin sensitivity in individuals with type 2 diabetes and prediabetes.

What the research says

Supports is higher

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

In plain English

Intermittent fasting lowers blood glucose levels and increases insulin sensitivity in people with type 2 diabetes and prediabetes.

See the scientific wording

Intermittent fasting reduces blood glucose levels and improves insulin sensitivity in individuals with type 2 diabetes and prediabetes.

Why this might work

When a person eats less often, the liver makes less sugar and the body's cells become more responsive to insulin, which pulls sugar out of the blood and lowers blood sugar levels.

What the research says

2 studies

  1. Study: Intermittent fasting for glycemic control in patients with type 2 diabetes: a meta-analysis of randomized controlled trials.

    This study found that people with type 2 diabetes who tried intermittent fasting had lower average blood sugar levels and lost weight, which means their bodies were better at using insulin to manage sugar. So yes, intermittent fasting helps lower blood sugar in these patients.

  2. Study: Comprehensive Analysis of Intermittent Fasting on Anthropometric Indices, Glycemic Control, and Serum Insulin Levels in Obese Patients with Type 2 Diabetes

    This study found that people with type 2 diabetes who ate only during an 8-hour window each day for four weeks had lower blood sugar levels, which is good. But their insulin levels didn’t change, so we’re not sure if their bodies became better at using insulin.
