The Health Map for Longevity & Aging
A Health Map is the navigation layer above the Topics. It shows the full path, the cross-area benefits, common mistakes, the contexts in which it applies, where experts disagree at the area level, and what is changing now.
Fasting depth: 12-hour overnight window vs. 14-16+ hour daily fast
Mainstream: A consistent 12-to-14-hour overnight fast captures most cellular cleanup benefit for most people, with lower risk of muscle loss.
Contested: Sinclair argues 14-to-16-hour daily fasts plus monthly multi-day fasts trigger deeper cellular repair unavailable at shorter durations.
What survives: Start with 12 hours nightly and hold it consistently for 4 to 8 weeks. Only extend duration after confirming muscle mass and protein intake are adequate.
The full Roadmap applies this pattern across every area-level tension. Path, Mistakes, Context, and What's changing now follow the same approach.
