Low-carb might not be the health solution you think it is.

After years of eating low-carb, fasting, and grinding through high-stress training, I started to notice something: my results were stalling, my sleep was off, and my labs were telling me I wasn't as metabolically "healthy" as I thought. When I added carbs back in—real food carbs from fruit, honey, and roots—my energy, recovery, and hormone markers improved across the board.

That shift led me back to today's guest, Jay Feldman, a health researcher and coach who's redefining what it means to be healthy through the bioenergetic model—the science of optimizing how our cells create and use energy.

In this episode, Jay and I dig deep into what's really driving modern metabolic disease—and spoiler alert—it's not sugar.

Jay explains why cellular energy production is the foundation of true health and how modern diets, stress, and lifestyle habits are interfering with that process. We discuss why low-carb and fasting protocols, while helpful short-term, can mimic stress states in the body and lead to burnout, hormonal dysfunction, and poor metabolic flexibility.

We also get into the massive role that seed oils and polyunsaturated fats (PUFAs) play in modern disease. Jay breaks down how these unstable fats damage mitochondrial membranes, reduce ATP production, and set off oxidative stress that disrupts everything from blood sugar regulation to brain health.

And, for anyone who still believes sugar is the bad guy, this episode flips that narrative upside down. Jay explains why sugar—especially from real foods—has been wrongly blamed for problems actually caused by PUFAs, endotoxin buildup, and poor energy metabolism.

Key Takeaways

• Energy, not restriction, drives health. When energy production drops, disease takes root.
• Low-carb can mimic disease states. The body reads low energy availability as stress.
• Seed oils are the real metabolic disruptors. They damage mitochondria and drive inflammation.
• Sugar isn't the villain. Whole-food carbohydrates can restore balance and energy.
• Endotoxin and gut imbalances are the hidden factors fueling chronic disease.
• Mitochondrial health is everything. The more stable your cellular structure, the longer—and better—you live.

Zane sits down with Dr. Mariza Snyder—practitioner, author, and host of Energized with Dr. Mariza—to reframe midlife for women as a window of opportunity, not a season of decline. She explains what perimenopause actually is, why so many providers miss it, and how proactive care (including lifestyle, strength training, and appropriately-timed HRT) can protect bone, brain, heart, mood, and metabolic health for the decades ahead. You’ll also hear about her upcoming book, The Perimenopause Revolution (launching October 21), which bundles training plans, recipes, and daily routines to support energy and body composition.

Why this matters: Menopause gets headlines, but perimenopause is where prevention pays off—estrogen and testosterone decline before the official 12-month mark, driving changes in bones, muscle, mood, and cardiometabolic risk. Getting ahead of it changes the next 40–50 years.

🎧 CTA: Listen now to learn how to spot perimenopause, build a plan you’ll actually follow, and use HRT as a bridge to better lifestyle—not a replacement for it.

• Perimenopause vs. menopause—clear definitions and why there’s no single diagnostic test for peri.
• What’s happening hormonally (ovary–brain “static,” FSH/LH shouting) and why symptoms vary.
• The midlife “window of opportunity” to protect healthspan (bone, muscle, heart, brain).
• Earlier risk rises: bone loss and cardiovascular risk begin before official menopause
• HRT as a catalyst: mood, motivation, and quality of life—why gatekeeping hurts outcomes.
• Lifestyle medicine still leads (sleep, training, nutrition), with HRT as a strategic “yes-and.”

In this eye-opening episode of Healthy AF, Zane sits down with renowned physician and author Dr. Cate Shanahan to expose what might be the biggest hidden driver of metabolic disease today: seed oils. Dr. Cate breaks down the hard science behind how oxidative stress—not sugar—is at the root of most chronic diseases, and why the most oxidized ingredient in the American diet is also the most overlooked.

You'll learn how seed oils create toxic byproducts, disrupt energy production at the cellular level, and set off a cascade of free radical damage that leads directly to insulin resistance. From debunking myths around omega-6s to explaining why most antioxidant supplements are useless, this conversation reframes the conversation around fat, inflammation, and what's truly making us sick.

🎧 Tune in to hear how ditching seed oils could be the most powerful change you make for your metabolic health—backed by science, not ideology.

What You'll Learn in This Episode:

• Why oxidative stress—not sugar—is the root cause of modern disease
• How seed oils fuel metabolic dysfunction through toxic byproducts
• The real formation of insulin resistance (it's not what you've been told)
• Why PUFA (polyunsaturated fats) + free radicals = a metabolic disaster
• Why omega-6 in whole foods isn't the problem
• The myth of omega-6 to omega-3 ratios causing disease
• Why most antioxidant supplements aren't worth your money
• How dietary dogma has buried real science about fats and health
