does fasting lower a1c

Fasting can have an impact on blood sugar levels, but its effect on A1C (a measure of average blood sugar over the past 2-3 months) is more complex. Here’s what you need to know:

• Short-term fasting: Fasting for short periods (e.g., intermittent fasting) may lower blood sugar levels temporarily, but it does not directly lower A1C. A1C reflects long-term glucose control, not short-term fluctuations.
• Long-term fasting: Prolonged fasting or extreme calorie restriction can lead to weight loss, which may improve insulin sensitivity and lower A1C over time. However, this should only be done under medical supervision.
• Lifestyle changes: Consistent healthy eating, regular physical activity, and medication adherence are more effective ways to lower A1C.

If you’re considering fasting, consult your healthcare provider to ensure it’s safe and appropriate for your health condition.
