The 4-Hour Body
Tim Ferriss
Ferriss applies his 80/20 lifestyle-design lens to the human body — fat loss, muscle gain, sleep, sex, sport. Rather than write a comprehensive textbook, he delivers minimum-effective-dose protocols for each domain. Some claims (slow-carb diet, Occam protocol) are well-supported; others (cold thermogenesis, ice-bath weight loss) are speculative. The 80/20 framework is the contribution; treat specific protocols as hypotheses.
