People with metabolic syndrome who follow intermittent fasting see their body’s insulin levels drop, meaning their body is better at using insulin to manage blood sugar.

Scientific Claim

Intermittent fasting reduces fasting insulin levels by 13.25 mU/L in adults with metabolic syndrome over interventions averaging 3 months, indicating improved insulin sensitivity.

Original Statement

“insulin plasma levels reduced by 13.25 uUI (95% CIs: −16.69; −9.82)”

Systematic Review With Meta-Analysis

Human

This study found that people with metabolic syndrome who tried intermittent fasting had much lower insulin levels—exactly as the claim says—and their bodies became better at using insulin, which is a good sign for their health.

Similar Assertions

Skipping meals at certain times of the day for a few months can slightly lower blood sugar levels in people with metabolic syndrome.

90%

After a few months of intermittent fasting, the body’s resistance to insulin drops by a measurable amount, making it easier for cells to absorb sugar from the blood.

82%

People with metabolic syndrome who try intermittent fasting lose about 4 pounds on average after a few months, even without counting calories.

82%

People with metabolic syndrome who follow intermittent fasting see a tiny but real drop in their triglyceride levels, which means their body is handling fat better.

80%

Intermittent fasting helps the body use insulin better—about as well as a common diabetes pill called pioglitazone—without needing to take medicine.
