Tools for Nutrition & Fitness | Dr. Layne Norton

In this episode, my guest is Dr. Layne Norton, Ph.D., one of the world’s top experts in nutrition and training for physical fitness. We discuss how to evaluate scientific evidence and the validity of different practices aimed at achieving fat loss, muscle strength and hypertrophy, microbiome health, vitality, and longevity. We explore many hotly debated topics, including fasting, seed oils, saturated fats, sugar, red meat, artificial/low-calorie sweeteners, and GLP-1 agonists (e.g., Ozempic). Additionally, we delve into the timing of protein and carbohydrate intake relative to fasting and exercise, fat loss and sleep, and the benefits of dietary protein and fiber on overall health. We also discuss how to accelerate hypertrophy and fat loss, improve strength, whether we need to train to “failure,” how to enhance exercise recovery, and how to manage pain. We cover training before versus after age 50, whether metabolism changes with age, and the connection between muscle health and longevity. We also address why certain behaviors and supplements might work for some people but not others. Listeners to this episode will benefit greatly from Layne’s science-based expertise on a wide range of topics, including health, nutrition, and fitness.
