Three questions, one honest answer. No quiz funnel, no email capture — just a recommendation based on your fasting experience.
Your starting point: —
The honest principle: the right fasting length is the longest one you can repeat without thinking about it. A boring 14 you keep beats a heroic 20 you quit — every time, no exceptions.
Progressing: when your current length feels uneventful for two straight weeks, add two hours. That's the whole advancement system. No jumps, no drama.
No. Longer fasts have different trade-offs, not bigger trophies. Daily consistency at 14–16 beats occasional 24s for almost every goal people actually have.
Rhythm first, results follow — most people feel the routine click in 1–2 weeks. The scale is the last place it shows up, not the first.
You can't. Start where the quiz puts you; adjust after two weeks of data. The quiz is a starting line, not a verdict.
