Nutrition Crisis in America

Today, I welcome Dr. Donald Layman back to The Dr. Gabrielle Lyon Show for a deep dive into his decades of protein research, the flaws in dietary guidelines, and the evolving landscape of nutrition. Together, we explore the real reasons behind the obesity epidemic, why decades of dietary advice have led us astray, and how we can reclaim metabolic health through high-quality protein intake. Dr. Layman shares compelling research on protein requirements, nutrient density, and how misleading narratives around fat and cholesterol have shaped our food choices. This conversation will challenge what you think you know about nutrition and empower you with evidence-based strategies for long-term health.

Key Points:

• The real reason behind the obesity epidemic
• Why 45% of Americans are consuming too little protein – and what that means for metabolic health
• How dietary guidelines became politically driven and scientifically flawed
• The food industry’s role in pushing low-nutrient, high-profit foods
• The dangers of refined grains and ultra-processed foods on body composition
• Breaking the stigma around red meat and cholesterol
