Early Time-Restricted Eating
The most metabolically powerful TRE variant. Eat early, finish by mid-afternoon.
Fasting
Mechanisms
Autophagy, ketosis, hormones, the switch
12 protocols. 2 rest on strong human evidence. Ordered with the best evidenced first.
12 protocols in Mechanisms
When the Body Runs on Fat
The well-established shift from burning glucose to burning fat-derived ketones, the real metabolic engine of fasting.
Time-Restricted Eating · Leangains Protocol
The most practiced and most studied fasting protocol on earth. 16 hours fasting, 8 hours eating.
Time-Restricted Eating · Six-Hour Window
A step deeper than 16:8. Six hours to eat, eighteen to fast, the autophagy onset zone.
Dawn-to-Sunset Daily Fast
The world's largest annual fasting experiment. Dawn-to-sunset, food and water, for a lunar month.
Eat-Stop-Eat · One Full Day
Dinner to dinner. One or two full-day fasts a week, the entry point to extended fasting.
Monk Fast · Day-Spanning Fast
Skip a full day of eating. Dinner to breakfast two days later, deep enough to matter.
Two-Day Water Fast
The midpoint of extended fasting. Deep ketosis, strong autophagy, manageable for many.
Three-Day Water Fast · Deep Autophagy Tier
At 72 hours, growth hormone surges 300%, autophagy peaks, and the immune system begins to reset.
The Cellular Recycling Process Behind the Hype
The cell's self-cleaning and recycling system, real, Nobel-winning science, and the single most overhyped word in fasting marketing.
What Fasting Does (and Doesn't) Do for the Gut
The real digestive physiology behind fasting, gut motility and microbiome shifts, separated from "gut reset detox" marketing.
Prolonged Water-Only Fasting
Five to seven days, water only. Deep fasting territory that belongs under medical supervision.
