Intermittent Fasting for Type 2 Diabetes: Indian Protocol Guide

What is Intermittent Fasting?

Intermittent fasting is an eating pattern that cycles between fasting and eating windows. The most popular method is 16:8 fasting — fast for 16 hours and eat during an 8-hour window daily.

Why IF Works for Type 2 Diabetes

• Lowers blood sugar levels by reducing insulin resistance

• Promotes weight loss (5-10% body weight in 3 months)

• Improves HbA1c by 0.5-1% in clinical studies

• Reduces inflammation and cardiovascular risk factors
