Protein reduces levels of the hunger hormone ghrelin while turning on four different satiety hormones (peptide YY, CCK, GLP, pancreatic polypeptide).
Hair and nails are largely made of keratin, a protein that supports their structure, growth, and strength.
Skin is the largest organ in your body and protein is critical for its key functions from collagen synthesis and cell turnover to maintaining elasticity and hormone balance.
Protein naturally helps build and maintain lean muscle mass and helps your body burn fat as fuel instead.
Your body requires significantly more energy (calories) to digest, absorb, and process protein than any other macronutrient (this is called the thermic effect of food) which revs your metabolism.
Protein is essential for the production of hormones and supports healthy hormone balance by slowing the absorption of sugar into the bloodstream (thus preventing blood sugar imbalances).
