The details, plainly.
The commitment is one day each month
Not one day a week, and not a schedule someone else sets for you. If you personally choose to fast more often, that's entirely your own practice — the community proposition stays one day a month, so it's always achievable.
You decide what fasting means for you
Members fast in different ways and for different reasons: reflection, faith, focus, discipline, gratitude, or solidarity with a cause. 1DF is a community and personal practice platform. Nothing here is medical advice — please speak to a healthcare professional if you have any health condition, are pregnant, or take medication.
Donations never pass through us
If your day stands for a cause, we link out to that charity's own official donation page. 1DF never collects, holds or processes money.
You choose how you appear
Full name, first name only, or completely anonymous. Your email address is never shown publicly.
You'll never fast alone.
Whether you're fasting for better health, spiritual growth, mental clarity, self-discipline or simply to support others, you'll always be part of a welcoming community walking the journey with you.
