Part II: We stop asking "what should humans eat?" and start with constraints. This essay proves the non-negotiable limits—from the Protein Ceiling in your liver to the fact that there is no essential carbohydrate—that define the human diet.
The isotopic evedence really clarifies things. I've always wondered why diet debates feel so circular, but framing it through trophic levels and the protein ceiling makes the ancestral pattern clearer. The nitrogen-15 values showing apex predator status for 2 million years is pretty compelling when you pair it with the metabolic constraints you outlined. Looking forward to seing how this translates into practical guidance in Part III.
Yes! The need for clarity among all the noise is what took me down this path. Glad it resonated with you too. Podcasts help clarify the points further in a surprisingly entertaining NotebookLM back and forth :)
