Types of Fasting Without Food: 12h, 24h, 36h or 48h – Which One Is Best for You? Fasting without food can be done in different ways: 12h, 24h, 36h or 48h. Each approach has unique benefits and risks. Discover which fasting method is best for your body, your goals, and how to apply it safely.

Fasting, also known as water fasting or black fasting, has become increasingly popular in recent years. From simple 12-hour breaks between meals to extreme 48-hour challenges, people explore fasting for weight loss, detoxification, and better metabolic health. But the essential question is: which type of fasting is right for you?
