Yours for good. No subscription, no renewal date, no account. - The 18:6, 20:4 and OMAD plans - Open fast: run with no fixed goal and stop when you decide - Deeper insights on the later fasting stages - Your complete fasting history, back to your very first fast HONEST BY DESIGN You pay once and that is it.

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
