What is Intermittent Fasting?
Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating.
Rather than focusing on what to eat, intermittent fasting focuses on when to eat. It's a scientifically-backed pattern that can help with weight management, metabolic health, and cellular repair. For more detailed information, you can refer to authoritative guides from Harvard Health and the Mayo Clinic.
