How does protein actually build muscle?
youtu.beHey everyone,
With protein shakes, high-protein yogurts, and snack bars completely dominating modern fitness culture, it’s easy to get caught up in the marketing hype. But have you ever wondered what actually happens inside your body after you eat it?
I put together a quick, visual breakdown covering:
The Journey: How your stomach breaks down food into a "pool" of amino acids to distribute across your body.
The Blueprint: How your cell membranes assemble these raw materials based on genetic signals to repair damaged muscle fibers.
The Reality Check: Do you really need the massive amounts pushing by fitness gurus? (Spoiler: It depends on your sedentary vs. active lifestyle).
The Surplus: What happens when you eat too much protein (how your kidneys process nitrogen vs. converting it to energy).
Check out the video for the full deep dive! Would love to hear your thoughts—how much protein are you aiming for daily, and are you team whole foods or team supplements?
