What is the fasting-stage ring?
As your fast continues, Ignis shows a ring that moves through five general wellness stages—fed, early fat-burning, fat-burning, ketosis, and autophagy—based on the time elapsed since your last meal. It is a visual way to follow estimated stages of your fasting window. Ignis is a tracking tool and does not provide medical advice.
