ABOUT THE FASTING STAGES The stage timeline is educational and is estimated from elapsed fasting time alone. Fasted does not measure your body. It is a general wellness tool, not medical advice. Intermittent fasting is not right for everyone, so talk to a qualified healthcare professional before you change how you eat. Questions or ideas? fasted@benbasha.com
