The Dietary Guidelines Are Failing Us

In this episode of The Dr. Gabrielle Lyon Show, Dr. Lyon is joined by Dr. Donald Layman, a world-renowned expert in protein metabolism and a pioneer in the field of nutritional science. With over 20 years of mentorship between them, Dr. Layman and Dr. Lyon dive deep into the flaws, myths, and future of U.S. Dietary Guidelines, offering a clear path to better health through smarter dietary decisions.

Dr. Layman shares his revolutionary perspective on why protein intake should focus on essential amino acids, how carbohydrates—not fats—are driving metabolic disease, and why outdated nutrition guidelines continue to mislead the public. From breaking down dietary biases to advocating for personalized nutrition, this episode is a must-listen for anyone striving for optimal health.

We dive into:

  • The history and evolution of the U.S. Dietary Guidelines, from the Food Pyramid to MyPlate.
  • Why "protein" as we know it is an outdated concept—and how essential amino acids are the real focus.
  • How processed carbohydrates are the primary drivers of obesity, diabetes, and heart disease.
  • The truth about saturated fats and cholesterol—and why the science contradicts public policy.
  • How low-carb, high-protein diets outperform standard dietary recommendations in nearly every metric.
  • Why nutrient-dense animal proteins are irreplaceable, despite plant-based advocacy.
