In this insightful episode of The Optimal Protein Podcast, I’m joined by Dr. Antonella V. Schwarz, Assistant Professor of Exercise Science, to uncover the powerful connection between strength training, protein intake, and achieving an optimal body composition.

As a former competitive bodybuilder turned researcher, Dr. Schwarz offers a unique perspective on how building muscle — not just losing fat — is the key to transforming your physique, metabolism, and long-term health.

What You’ll Learn in This Episode:

✅ Why muscle, not fat loss, is the real driver of better body composition

✅ The crucial differences between hypertrophy-focused bodybuilding and resistance training for health and strength

✅ How building skeletal muscle mass supports metabolic health, boosts your resting metabolic rate (RMR), and aids in fat loss

✅ What Skeletal Muscle Quality (SMQ) is and why it’s a better predictor of strength than traditional fat-related metrics

✅ Why muscle-related metrics outperform body fat percentage when assessing strength, performance, and overall health

✅ Practical strategies for increasing muscle mass while improving body composition

✅ Why focusing on adding positive habits — like protein and strength training — is far more effective than focusing on removing foods or behaviors

✅ The surprising ways that muscle preservation can slow aging, improve independence, and enhance overall vitality

Key Quotes from Dr. Schwarz:

💬 “Increasing muscle mass is like hedging your bets on life — it’s your best investment for longevity.”

💬 “Instead of focusing on taking away, focus on adding — more protein, more resistance training, more positive habits.”
