Intermittent fasting significantly reduces diastolic blood pressure but has no significant effect on systolic blood pressure, fasting plasma glucose, or HbA1c in overweight and obese adults.

Intermittent fasting can help lower diastolic blood pressure, a key component of heart health. However, it may not significantly affect systolic blood pressure or blood sugar levels (FPG, HbA1c) in the short term. For comprehensive cardiometabolic health, combine IF with other lifestyle interventions and monitor your specific markers.

In addition, IF significantly reduced DBP (MD: -3.30 mmHg, 95% CI: -5.47, -1.13) but had no significant effect on SBP, FPG and HbA1c.
