After a few months of eating only during certain hours, people with metabolic syndrome see a tiny but real drop in their average blood sugar levels over time.

Scientific Claim

Intermittent fasting reduces HbA1c by 0.08% in adults with metabolic syndrome over interventions averaging 3 months, suggesting a small but statistically significant improvement in long-term glucose regulation.

Original Statement

“glycosylated hemoglobin reduced by 0.08 (95% CIs: −0.25; −0.10)”

Systematic Review With Meta-Analysis

Human

This study found that people with metabolic syndrome who tried intermittent fasting lowered their HbA1c (a measure of long-term blood sugar) by 0.08%, which is a small but real improvement in how well their body controls sugar over time.

Similar Assertions

If most people in the study don’t have high blood sugar to begin with, intermittent fasting doesn’t make much of a difference in their long-term average blood sugar.

96%

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

83%

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.

79%

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

73%

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.
