Intermittent Fasting for Beginners: Your Complete 2026 Guide

Intermittent fasting (IF) has become one of the most popular health trends worldwide—and for good reason. This beginner's guide will walk you through everything you need to know to start your fasting journey successfully.

What Is Intermittent Fasting?

Intermittent fasting isn't a diet—it's an eating pattern. Instead of focusing on what you eat, IF focuses on when you eat. You cycle between periods of eating and fasting.

Popular Fasting Methods

20:4	20 hours	4 hours
OMAD	23 hours	1 hour

For beginners, the 16:8 method is the easiest starting point.

• Weight loss - Your body burns fat for fuel during fasting
