The rate of weight loss during intermittent fasting varies significantly based on your starting Body Mass Index (BMI), body fat percentage, and chosen fasting protocol. Individuals with a higher starting BMI (over 30) often lose 3 to 5 pounds per week initially due to rapid insulin reduction, while individuals closer to their ideal body weight lose a steady, healthy 0.5 to 1.5 pounds of pure fat per week.
