Does Intermittent Fasting Help with Blood Sugar?

Yes, intermittent fasting can help improve blood sugar control and insulin sensitivity. Studies show that time-restricted eating patterns can reduce fasting glucose levels by 3-6% and improve insulin resistance markers. The most researched approaches include 16:8 fasting (eating within an 8-hour window) and alternate-day fasting. During fasting periods, your body depletes glucose stores and becomes more efficient at using insulin. Research involving over 1,000 participants found that intermittent fasting reduced HbA1c levels by an average of 0.2-0.9%. However, people with diabetes or blood sugar disorders should consult their healthcare provider before starting any fasting regimen, as medication adjustments may be necessary to prevent dangerous blood sugar drops.
