mito: fasting biology

mito helps you understand what happens inside the body during fasting.

Instead of simply counting hours, mito visualizes the metabolic stages of fasting. Animated stages illustrate how the body gradually shifts from digestion and blood sugar regulation to stored glucose use and increasing reliance on fat metabolism.

Most fasting apps simply count hours. mito explains how your metabolism gradually changes during a fast and what these changes mean for your body.

Each stage includes a short article that explains what is happening in the body, making the biology of fasting easier to understand — not just something you track.

Beyond the stages, mito also includes a growing collection of articles that explore different aspects of fasting and metabolism.

You can also track your fasting history, recognize patterns in your fasting habits, and keep notes about how different fasts feel.
