Nutrition & DietLayne Norton Breaks Down the Real Science of Fat Loss and Muscle Building
In this Huberman Lab Essentials episode, Dr. Layne Norton, a nutrition and metabolism PhD, walks through the evidence behind common dietary questions. Topics include how calories in versus calories out actually works in practice, why protein intake is central to both fat loss and muscle gain, and how Non-Exercise Activity Thermogenesis (NEAT) influences daily energy expenditure more than most people realize. Norton also addresses animal versus plant protein quality, the role of leucine in muscle synthesis, the real evidence on artificial sweeteners and seed oils, and why creatine monohydrate remains one of the most well-supported supplements. The episode is designed as a practical, science-grounded guide for anyone looking to improve body composition sustainably, without resorting to extreme or fad dietary approaches.
