What is Intermittent Fasting (IF)?
Intermittent Fasting is an eating pattern that cycles between periods of fasting and eating. It doesn't specify which foods you should eat, but rather when you should eat them. Common benefits cited by researchers include improved metabolic health, weight loss support, and increased cellular repair (autophagy).
Popular Fasting Methods
- 16:8 (The Leangains protocol): You fast for 16 hours and eat during an 8-hour window. For many, this is as simple as skipping breakfast and not eating anything after dinner.
- 18:6 (Advanced): A more restrictive window that leaves 6 hours for eating.
- 20:4 (The Warrior Diet): One large meal at night within a 4-hour window and small snacks in the day.
- 12:12 (Beginner): A balanced approach of equal fasting and eating time.
