How much protein should you eat per day? In this video, Dr. Justin Marchegiani breaks down the science of protein intake, amino acids, and muscle growth so you can optimize your health and performance.
Here’s what you’ll learn:
✔ Why protein is essential for building muscle, hormones, and recovery
✔ The difference between plant vs. animal protein sources
✔ Why certain amino acids (methionine, lysine, leucine, isoleucine, valine) matter for energy and muscle growth
✔ How much protein you actually need — from 0.4 to 1 gram per pound of body weight
✔ Why activity level, stress, and workouts change your protein needs
✔ The benefits of amino acid shakes and post-workout protein timing
✔ How gut health and digestion impact your ability to absorb protein
Dr. Justin also explains the thermic effect of protein, how amino acids fuel your muscles directly, and why a balanced intake supports better recovery, energy, and mood.
Whether you’re lifting weights, looking to maintain muscle as you age, or simply want to support your hormones and metabolism, this video gives you a practical rule of thumb to calculate your daily protein needs.
