In this episode, I’m joined by Dr. Ty Beal—global nutrition researcher and Senior Technical Specialist at the Global Alliance for Improved Nutrition (GAIN)—to uncover the hidden epidemic of micronutrient deficiencies worldwide. From food access and affordability to ultra-processed diets and nutrient bioavailability, we explore how modern food systems are failing billions and what needs to change to truly make the world healthier.

We cover:

• Why 3 billion people can’t afford a healthy diet—and how that affects nutrient status
• The most common global and U.S. micronutrient deficiencies (and why they’re often overlooked)
• Why women and children are especially vulnerable during pregnancy, infancy, and adolescence
• The role of ultra-processed foods in displacing nutrient-rich options
• How bioavailability, anti-nutrients, and the “food matrix” impact your real nutrient intake
• Why plant-based diets aren’t always safer—and the hidden risks of nutrient shortfalls
• The science behind biofortification, food system reform, and why animal-source foods stil matter
• What the U.S. gets wrong about food guidelines, global trade, and nutritional equity

Whether you care about maternal health, child development, or just making better nutrition decisions, this is a vital conversation about nutrient density, food justice, and global health.

Who is Dr. Ty Beal?

Dr. Ty Beal is a Senior Technical Specialist and global nutrition scientist at the Global Alliance for Improved Nutrition (GAIN) where he leads research on global food systems, nutrient inadequacy, and diet quality. His work bridges science and policy to help address the world’s most pressing nutrition challenges—especially among vulnerable populations. He’s published extensively on micronutrient gaps, ultra-processed foods, and global dietary patterns, and is one of the most cited voices on nutrition equity in developing nations.

In today's episode, I had the chance to speak to muscle physiology researcher and science communicator Dr. Lauren Colenso-Semple. Together, we unpack the common claims around hormones and training—from whether you should change your workouts based on your cycle, to the real effects of fasted cardio and birth control on performance and muscle growth. We also explore how menopause affects body composition, what the science actually supports when it comes to training differences between men and women, and why some of the most persistent myths about women’s physiology are based more on assumption than evidence.

What You’ll Learn:

• Why women’s physiology is not a limitation for building muscle
• Whether training around your menstrual cycle or avoiding fasted workouts is necessary
• The truth about oral contraceptives and their impact on performance, hypertrophy, and strength
• How menopause affects body composition—and what you can do about it
• Why consistency and progressive overload matter more than hormone fluctuations
• How much protein and resistance training women actually need—and when to eat it

This conversation is for every woman who’s been told her physiology is too complicated to train effectively. It’s not. The science is finally catching up—and Lauren is helping lead the charge.

Timestamps:

00:00 – Introduction to the episode and what it covers: hormones, menstrual cycles, birth control, and muscle growth.

01:00:29 – Training volume and progressive overload: what actually matters for hypertrophy.

01:02:51 – Fasted training and cortisol:...

In this episode, I’m joined by Dr. Abbie Smith-Ryan—one of the leading researchers in exercise physiology and women’s metabolism—to unpack the science of how women should be training through perimenopause, postmenopause, and beyond. We dive into the physiological changes that impact body composition, performance, and recovery—and how to adjust training and nutrition to match.

We discuss:

• How high-intensity interval training (HIIT) improves VO₂ max, fat oxidation, and muscle quality in women
• Whether fasted training helps or hurts, and why so many women are under-fueled
• What the science really says about lifting heavy and building muscle over 40
• Nutrient timing, rest intervals, and why sex-based differences in physiology matter
• What we still don’t know about hormone therapy, protein needs, and female-specific adaptations

If you’re navigating training, muscle loss, or metabolic changes through midlife, this conversation will give you clarity, confidence, and evidence-based strategies you can actually use.

Who is Dr. Abbie Smith-Ryan?

Dr. Abbie Smith-Ryan is a leading expert in exercise physiology and sports nutrition, currently serving as Associate Chair for Research and Director of the Applied Physiology Lab at the University of North Carolina at Chapel Hill.

This week in the studio, I'm joined by Dr. Nick Barringer—Army Ranger, performance nutrition expert, and one of the sharpest minds in military and metabolic health. Together, we cut through the noise around today's most controversial nutrition topics. If you’ve ever felt whiplash trying to make sense of conflicting headlines, this episode is your science-based compass.

What’s really going on with artificial sweeteners like sucralose and aspartame? Are seed oils toxic—or just misunderstood? And what’s the actual science behind popular supplements like creatine, testosterone boosters and fat burners?

Dr. Barringer brings two decades of elite military and research experience to help us separate hype from evidence—while sharing real-world tools that help people perform, think, and feel better.

We cover:

• Whether sucralose and other artificial sweeteners damage DNA or gut health
• What to actually worry about with food dyes
• Seed oils, inflammation, and what most people get wrong about them
• Protein and carb dosing for people over 40 (and how to think about fiber and fat)
• Why creatine is still the most underrated supplement for muscle and brain function
• Tactical hydration tips (and how sweat composition varies with diet)
• Hidden risks in testosterone boosters and “fat burners”
• Practical takeaways for elite performance, healthy aging, and being stronger at any age

In this episode, I’m joined by Dr. Melanie Cree—physician-scientist, pediatric endocrinologist, and one of the leading researchers redefining how we understand and treat Polycystic Ovary Syndrome (PCOS). PCOS affects millions of women, yet it's still underdiagnosed, misunderstood, and often mistreated. Dr. Cree cuts through the confusion, offering a deeply scientific yet compassionate look at what’s really driving this complex condition—from insulin resistance and mitochondrial dysfunction to skeletal muscle quality and fertility trajectories across a woman’s lifespan.

We cover:

• Why PCOS isn’t a single disease—and what two phenotypes may explain the full picture
• How muscle, liver, and fat interact in PCOS
• The misunderstood role of testosterone, insulin, and SHBG in diagnosis
• What muscle biopsies reveal about teenage girls with PCOS
• Intramuscular fat, mitochondrial impairment, and the true cost of sedentary muscle
• How early lifestyle and exercise interventions could change the future of PCOS care
• What GLP-1 agonists and amino acid supplements might offer for treatment

Whether you’re a clinician, patient, or advocate for women’s health, this episode will give you a whole new lens on PCOS—and why skeletal muscle may be the most overlooked (and powerful) organ in the conversation.

Who is Dr. Melanie Cree?

Dr. Melanie Cree is a board-certified pediatric endocrinologist and Associate Professor at the University of Colorado and Children’s Hospital Colorado, where she directs a leading multidisciplinary PCOS clinic. Her research bridges metabolic medicine and muscle physiology, with clinical trials exploring semaglutide, amino acid therapy, liver metabolism, and insulin resistance in adolescents.
