1. What Is Intermittent Fasting?

Intermittent fasting is an eating pattern where you alternate between periods of eating and fasting. It doesn’t prescribe what you eat—but rather when you eat.

It’s not about starvation.

You still eat your daily calories, but within a specific time window.

2. How Does It Work?

During fasting periods, insulin levels drop, allowing your body to burn stored fat more efficiently. Fasting also supports cellular repair and hormone regulation.

In short:

• Fewer meals = fewer calories
• Improved insulin sensitivity
• Enhanced fat burning and energy efficiency
