What Is Intermittent Fasting?

Intermittent Fasting is an eating pattern where you cycle between periods of eating and fasting. Instead of focusing on what to eat, it focuses on when you eat.

Many people practice fasting for weight loss, better metabolism, and improved overall health. This method has become popular worldwide because it is simple and flexible.

Research shows that fasting can help the body switch from using sugar as fuel to using stored fat for energy.

According to research from the National Institute on Aging, intermittent fasting may help improve metabolic health and support healthy aging.

How Intermittent Fasting Works

When you eat food, your body uses glucose for energy. During fasting hours, glucose levels drop and the body starts burning stored fat.

This process is linked to a biological process called:

Autophagy — a natural process where the body removes damaged cells and regenerates new ones.

Many scientists believe this process helps improve longevity and disease prevention.
