The Proof with Simon Hill

In today’s episode of The Proof, we dissect a video featuring Dr. Gabrielle Lyon discussing protein sources and the importance of leucine for muscle building. I break down her claims, compare animal and plant protein sources, and explore the latest research on muscle protein synthesis and long-term health outcomes.

  • Introduction (00:00)
  • Dr. Lyon's Argument: Animal vs. Plant Protein (00:17)
  • Critiquing Dr. Lyon's Protein Source Comparisons (01:14)
  • Evaluating the Leucine Threshold Hypothesis (03:13)
  • Plant-Based Protein Sources: A Deeper Look (06:30)
  • Scientific Studies on Protein and Muscle Growth (15:40)
  • Conclusion (25:17)

Key Discussion Points:

  • Dr. Lyon’s Claims
  • Comparing Protein Sources
  • The Leucine Threshold Debate
  • Beyond Muscle Protein Synthesis

Plus, if you watch/listen all the way to the end I share a fun personal story about my 90-year-old grandma who took up walking 10km a day!

Enjoy,

Simon

Creatine questions and misconceptions | Simon Hill, Msc, Bsc

Think creatine supplementation is all about timing and loading?

You might be surprised. In episode #350, I dive into six frequently asked questions about creatine, inspired by a follow-up review by Dr. Jose Antonio and colleagues. Whether you’re just starting with creatine or already supplementing, this episode will provide clarity and practical insights.

Learn why timing matters less than consistency, whether co-supplements like carbs enhance effectiveness, and if creatine affects blood pressure, fertility, or urine production. This is your ultimate guide to making informed decisions about creatine supplementation.

Key highlights include:

  • Does the timing of creatine intake matter?
  • Do other compounds enhance creatine’s effectiveness?
  • Does creatine affect blood pressure or increase urine production?
  • Is creatine safe to use during pregnancy?
  • Can creatine supplementation impact male fertility?

Discover insights and supporting studies in the full show notes.

  • Introduction (00:00)
  • Timing of Creatine Supplementation (02:50)
  • Enhancing Creatine Effectiveness with Other Compounds (05:06)
  • Creatine and Blood Pressure (06:31)
  • Creatine and Urine Production (08:35)
  • Creatine Safety During Pregnancy (10:56)
  • Creatine and Male Fertility (12:49)
  • Recap and Final Thoughts (14:37)

Are Podcast Hosts Spreading Health Misinformation? Plus 4 New Studies You Need to Know | Drew Harrisberg, Bsc

In this episode, I sit down with Drew Harrisberg to break down four new studies covering selenium intake, plant vs. animal monounsaturated fats, workout recovery strategies, and resistance training techniques. But beyond the science, we also discuss a critical issue in health communication—the responsibility of podcast hosts when platforming health claims.

Using recent episodes of Diary of a CEO featuring Dr. Mindy Pelz and Dr. Sarah Berry, we examine how misinformation spreads, why extreme views persist, and how listeners can differentiate science from pseudoscience.

  • Introduction (00:00)
  • Ross Walker: The Comedian Cardiologist (03:23)\
  • The Importance of CGM and Misleading Health Advice (12:29)
  • Scientific Method and Logical Consistency (24:29)
  • Debunking Myths: Seed Oils and Health (32:59)
  • The Power of Anecdotes vs. Scientific Evidence (42:54)
  • Jordan Peterson and Elon Musk's Viral Clip (50:13)
  • Personal Humility and Dietary Failures (53:07)
  • Study on Recovery Modalities: Hot vs. Cold Baths (01:00:56)
  • Minimum Effective Dose for Resistance Training (01:19:34)
  • Selenium Intake and Brazil Nuts (01:31:14)
  • Monounsaturated Fats and Type 2 Diabetes Risk (01:48:32)
  • Concluding Thoughts (02:21:01)

Key Discussion Points:

  • Dr. Sarah Berry’s Diary of a CEO appearance and the backlash
  • The seed oil controversy—do they really cause inflammation?
  • How to spot red and green flags in health claims
  • Four new studies on nutrition and exercise, including whether training to failure is necessary for muscle growth
