Why Protein Isn’t Always Enough: Anabolic Resistance, Obesity, and Protein Efficiency | Dr. Nick Burd

Muscle health isn’t just about how much protein you eat—it’s about how your body uses it. And for people with obesity or advancing age, that process can become less effective, even with optimal nutrition. In this episode, I am joined by Dr. Nick Burd, one of the world’s leading r ... Show More

In this episode, I discuss the essential role of skeletal muscle in health and performance. I explain what skeletal muscle is made of, how it works, and its role as an integral organ system for physical and mental health. I explain how to focus on skeletal muscle quantity (total muscle) and muscle quality (functionality, speed, power, strength) to ensure you function and perform at the highest levels.

I explain the difference between slow- and fast-twitch muscle fibers and why skeletal muscle is uniquely adaptable to exercise, nutrition, and lifestyle factors. I also explain why resistance training becomes increasingly critical for healthy aging and disease prevention.

I explain how to use the "Three Is" of investigate, interpret, and intervene to determine if you have enough muscle, if it's functioning well, and protocols to improve muscle quality and quantity. Listeners of this episode will understand why skeletal muscle is so essential to care for and how to enhance muscle quantity and quality to optimize physiology, performance, and longevity.
