Intermittent fasting is not suitable for everyone, including pregnant women, individuals with a history of eating disorders, or those with certain medical conditions. Consult your doctor before changing your eating patterns.

16:8 Intermittent Fasting is the most popular protocol in 2026 for a reason: it's sustainable, effective, and fits into almost any lifestyle. It provides a perfect balance between metabolic health benefits and daily practicality.

What is 16:8?

It means you fast for 16 hours and compress your eating into an 8-hour window. For most people, this looks like finishing dinner by 8:00 PM and not eating again until 12:00 PM the next day. During the 16-hour fasting window, you consume zero-calorie beverages like water, black coffee, or plain tea.

A Typical 16:8 Timeline:

The Benefits of Autophagy

By the 14th to 16th hour of your fast, your body begins a critical process called autophagy—cellular self-cleaning. This is where your cells degrade and recycle damaged components, potentially improving longevity, cellular function, and skin health. Intermittent fasting also helps stabilize insulin levels, making it easier for your body to access stored fat for fuel.

Using our 2026 Fasting Scheduler helps you visualize these windows and align them with your daily routine, ensuring you maximize the metabolic benefits of your fasting protocol.
