Welcome to part three of our macronutrient series! We’ve covered fats and carbs, and now it’s time to take a look at the third and final macronutrient: protein. In this simple guide to protein, you’ll learn about:

  • The structure of protein
  • Complete vs. incomplete proteins
  • How you digest protein
  • Denatured protein (and whether it’s good or bad)
  • Protein’s many benefits, and how your body uses it
  • Good sources of protein

Protein gets a lot of credit for building stronger muscles. Rightly so – it’s fundamental in muscle repair and growth. But protein’s role in your body goes far beyond getting you jacked. You can also use it to enhance metabolism, fat loss, mood, brain function, hormonal balance, and more.
