Q&A Highlights - August 2025

About this video

In this August 2025 Q&A highlights reel, Yurth ranks protein sources for muscle building, arguing whey isolate is her preferred option because of its leucine content and immune-related components, with egg protein next and plant options lower. She criticizes oat milk as a largely sugar-driven drink, advises lifting before cardio when muscle and metabolic health are the priority, and outlines a muscle-building approach for women in their seventies that combines hormone assessment, leucine-rich protein spread through the day, creatine, resistance and balance training, and growth-hormone-related options she discusses at a topic level. She also praises exogenous ketones, discusses an Alzheimer’s blood test while questioning amyloid causality, and warns against acetaminophen before surgery.

Key takeaways

• Judge a protein for muscle goals largely by its leucine and complete amino-acid profile, not just total grams
• Sequence training around the goal: lift first if preserving muscle is the metabolic priority
• Building muscle later in life, Yurth argues, requires checking hormones, protein, creatine, and recovery together
• Treat a positive Alzheimer’s biomarker test as information to interpret, not proof of a single cause
• Ask what routine pre-surgery medicines do to detox pathways before accepting them automatically
