Why Protein Matters

The nutrient that protects everything else

Most people know they should eat more protein. Fewer know why it works.

This one goes a level deeper: the mechanism behind muscle growth, the reason protein costs your body more calories to digest than carbs or fat, and how it changes the hunger and fullness signals that make eating well feel hard.

What's inside

  • How muscle protein synthesis drives growth and repair
  • Why protein has the highest thermic effect of any macronutrient
  • How protein influences the hormones that control your appetite
  • What body recomposition means and how protein makes it possible
