Overview

Why this framework exists

Darwin's Rule is a guideline for eating that prioritizes optimal fertility. The idea is that if you eat for optimal fertility, everything else, including athletic performance and overall health, will fall into place. This approach emphasizes the importance of considering the scientific evidence and not just following a particular diet or ideology.

Origin story

How this framework came to be

The concept of Darwin's Rule was developed by Timothy Ferriss, who researched and interviewed various experts in the field of nutrition and health. He found that many people who followed a vegan or vegetarian diet experienced hormonal issues and other health problems, and he concluded that some form of animal product is necessary for proper hormone production.
