What is Intermittent Fasting? A Comprehensive Guide to Types, Effects, and Practice

Focusing on "when to eat" rather than "what to eat", Intermittent Fasting (IF) is gaining global attention. Research shows it's effective not just for weight loss, but also for health and longevity.

Definition

Intermittent Fasting (IF) is a dietary pattern that alternates between periods of fasting and eating. It focuses on "when" to eat rather than "what" to eat, more of an eating schedule than a traditional diet.

Unlike traditional diets that focus on calorie restriction or eliminating specific foods, intermittent fasting limits eating times. During fasting periods, the body begins using stored fat for energy, triggering various metabolic changes.
