Understanding A1C
A1C measures your average blood sugar over 2–3 months, reflecting long-term glucose control. Intermittent fasting may help lower A1C by improving insulin sensitivity (Healthline).
Why Monitor A1C?
- Evaluate diabetes management or risk.
- Assess the impact of fasting on glucose control.
- Guide discussions with your healthcare provider.
