Is Processed Meat Really Bad for You? with Dr. Frederick Leroy.

ReThink Health with Dr. Autumn Smith

IN THIS EPISODE Most of us hear the words “processed meat” and immediately think unhealthy. But is a traditionally fermented salami really the same thing as an ultra-processed meat snack packed with sugar, fillers, and additives? In this episode of the ReThink Health Podcast, I sit down with Dr. Frederick Leroy, a professor and food scientist who has spent decades studying animal-source foods, fermentation, food processing, and human nutrition. Dr. Leroy explains why lumping every processed meat into one category misses some important details. (Humans have been...

Grass-Fed Beef Has 3x More of This Critical Nutrient (Shocking Results) with Dr. van Vliet.

ReThink Health with Dr. Autumn Smith

IN THIS EPISODE We love to argue about food like it’s simple—grass-fed vs. grain-fed, animal vs. plant, protein powder vs. “real food.” But the truth is… we’re barely scratching the surface of what food actually contains. In this episode of the ReThink Health Podcast, I sit down with Dr. Stephen Van Vliet (Utah State University), a researcher on the front lines of nutrient density, metabolomics, and regenerative agriculture. His lab is helping answer the questions most of us feel are important, but don’t have clear, evidence-based answers for yet: Does food quality actually...

Is Your Bad Mood Actually a Nutrient Deficiency? with Julia Ross.

ReThink Health with Dr. Autumn Smith

IN THIS EPISODE When we feel anxious, down, or just not like ourselves, we usually assume something in our life is to blame. But what if sometimes the problem isn’t your life… it’s that your brain is missing a crucial nutrient?

After more than 40 years of clinical work, she’s helping answer some fascinating questions about the connection between protein, brain chemistry, and how we feel. ...

Can Eating Meat Actually Be Healthy? with Dr. Drew Pinsky

ReThink Health with Dr. Autumn Smith

IN THIS EPISODE We’re told meat is dangerous, fat is the enemy, and cereal somehow ends up with a better “health score” than beef or eggs. But what if much of that narrative is based on oversimplified science… and not the full picture of human biology? In this episode of the ReThink Health Podcast, I sit down with Dr. Drew Pinsky to unpack his personal health transformation and what he believes is the powerful link between diet, inflammation, brain function, and long-term metabolic health. Drawing from decades in medicine and his own experience shifting to a low-carb,...

The Glyphosate Problem Nobody's Talking About (Can Glycine Fix it?) with Dr. Stephanie Seneff.

ReThink Health with Dr. Autumn Smith

Glyphosate is one of the most widely used herbicides in the world. But what if its impact on human health goes far beyond the plants it was designed to kill? In this episode of the ReThink Health Podcast, Dr. Stephanie Seneff and I dive into one of the most controversial and fascinating theories in modern health: the possible connection between glyphosate, glycine, and chronic disease. Glycine is an amino acid that plays a massive role in proteins, collagen, digestion, detoxification, immune function, and cellular repair. And according to Dr. Seneff’s research,...

Is Modern Food Making Us Sicker? with Dr. Eric Berg

ReThink Health with Dr. Autumn Smith

What if the health of your food starts long before it reaches your plate? In this episode of the ReThink Health Podcast, Dr. Eric Berg and I explore the fascinating connection between soil health, regenerative farming, nutrient density, metabolic health, and the ketogenic diet. Dr. Berg shares his personal journey from being a self-described “junk food junkie” struggling with severe health issues… to discovering low-carb nutrition, healthy keto, and the powerful role food quality plays in long-term wellness. But this conversation goes far beyond keto. We dive deep into the modern...

Rethinking Saturated Fat and Healthy Aging with Dr. Stephanie Venn-Watson

ReThink Health with Dr. Autumn Smith

For decades, we’ve been told to avoid saturated fat. But what if one specific saturated fat is actually essential for healthy aging? In this episode of the ReThink Health Podcast, Dr. Stephanie Venn-Watson and I discuss a groundbreaking discovery that could completely reshape how we think about fat, aging, and metabolic health. While studying aging Navy dolphins, Dr. Venn-Watson and her team uncovered something unexpected… The healthiest, longest-living dolphins consistently had higher levels of a little-known fatty acid called C15:0 (pentadecanoic acid). And researchers now believe C15...

The Supplement Industry Is Lying To You with Robyn Openshaw - Green Smoothie Girl

ReThink Health with Dr. Autumn Smith

Most of us assume supplements are helping us. After all… they’re marketed as essential for filling nutrient gaps, supporting immunity, and optimizing health. But what if that assumption deserves a closer look? In this episode of the ReThink Health Podcast, I sit down with Robyn Openshaw (author, researcher, and founder of GreenSmoothieGirl) to pull back the curtain on the supplement industry. What she uncovered after years of deep research may completely change how you think about the pills in your cabinet. From synthetic vitamins to fish oil, collagen, and beyond, Robyn explains why...

The Real Reason You Can't Lose Weight | It's Not What You Think (Dr. Hyman reveals)

ReThink Health with Dr. Autumn Smith

IN THIS EPISODE We’ve been told weight loss is simple: “Eat less and move more.” And if you can’t… it must be a willpower problem. But Dr. Mark Hyman says this story doesn’t match what we’re seeing in real life… or what the science actually shows. In this episode of the ReThink Health Podcast, I sit down with Dr. Hyman to unpack the real drivers behind stubborn weight gain (and why so many people feel like their body is working against them). We talk about how today’s food environment is built around ultra-processed, hyper-palatable ingredients...

Fasting gets talked about a lot… but most people still don’t understand why it works or how to do it in a way that actually feels sustainable (especially if you’re a woman navigating stress, hormones, and a busy life).

In this episode of the ReThink Health Paleo Podcast, I’m joined by fasting expert Dr. Mindy Pelz, who breaks down the science in a way that’s clear, empowering, and surprisingly doable.

We talk about why your body has two fuel systems, how fasting helps you switch between them, and what starts to happen in the body at key milestones like 13–15 hours, 17 hours, 24 hours, and beyond.

You’ll also learn why fasting can feel amazing for some people, terrible for others, and how to train your body to fast safely instead of forcing it.

Most importantly, Dr. Mindy shares practical ways to get started, plus how women can fast in a way that sustainably supports their hormones.

You’ll learn:

Where the fasting sweet spot window is for autophagy, your body’s cellular “cleanup mode”
The incredible benefits of fasting for up to 24 hours
Why some people experience a “fasting high”
Why women may need to fast differently depending on where they are in their cycle
How to start if you “can’t fast” (and why you may have experienced issues in the past)
Simple strategies to ride out hunger waves without white-knuckling
Other easy ways to support autophagy beyond fasting

If you’ve ever wondered whether fasting is actually safe, effective, or “for you,” this episode will help you understand the science and find a rhythm that supports your energy, metabolism, brain, and hormones.
