Lean Protein vs. Whey Protein: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 13, 2023
Lean protein refers to protein sources low in fat, while whey protein is a complete protein derived from milk.

Key Differences

Lean protein encompasses a variety of protein sources that are low in fat, like chicken breast, turkey, and legumes. Whey protein, on the other hand, is a byproduct of cheese production, derived specifically from milk. It contains all essential amino acids, making it a complete protein, while lean protein sources vary in their amino acid profiles.
