Protein is far more than a building block for muscle—it’s essential for metabolic health, insulin sensitivity, and preventing conditions like type 2 diabetes and sarcopenia. But how much do we truly need? And could too much protein, especially from meat, actually be harmful? This episode challenges the conventional RDA of 0.8 g/kg, presenting research that supports higher intakes of 1.2–2 g/kg for maintaining muscle, improving body composition, and promoting longevity. We also confront myths around protein timing and the so-called "anabolic window.” Lastly, we address concerns about protein’s links to cancer, heart disease, and kidney function, showing how exercise can redirect growth factors like IGF-1 to promote repair while mitigating risks.
