Context

Grocery shelves are suddenly packed with protein-fortified cereal, chips, and even Pop-Tarts. The packaging implies a simple equation: eat more protein, get stronger muscles. But in an essay published on 21 August 2026, a biologist stops to ask what the human body actually does with all those extra amino acids. Stripping away the modern supermarket sales pitch, the essay clarifies exactly what it takes to build physical strength, and why a candy bar with a fitness label is usually just a candy bar.
