Why Justin Nault Says Everything You Eat Is Either Food or Poison

Guest: Justin Nault – Certified Nutritional Therapist, Fitness Nutrition Specialist, Founder of Clovis, and Host of The Clovis Culture Podcast

From Fat Kid to Fitness Obsession

Justin Nault didn’t start his wellness journey in a lab or clinic. It began with a mirror and a mission. After growing up overweight and idolizing action stars like Arnold Schwarzenegger, Justin dove headfirst into fitness. He lifted weights obsessively, trained as a boxer, and performed as a professional musician under bright stage lights 300 nights a year. On paper, he was fit. But behind the scenes, he was battling body dysmorphia, disordered eating, and punishing workout schedules—all in the pursuit of a look he could never quite achieve.

The Turning Point: When Nutrition Got Personal

Everything changed when his newborn niece, Savannah, was born with a rare genetic disorder and given less than three years to live. After doctors suggested a ketogenic feeding formula to reduce her seizures, Justin took a closer look at the ingredients—and was shocked. The formula was filled with hydrogenated oils, artificial flavors, and synthetic vitamins. It was labeled "medical food," but it looked more like a chemical cocktail.

A neurologist admitted he'd never read the label.

That moment was Justin’s wake-up call: “No one is coming to save us.”

Real Food or Poison?

This moment became the foundation of Justin’s nutritional philosophy: Everything you eat is either food or poison.

Yes, calories matter—but only when you're talking about real food. Once metabolic toxins enter the picture, the calories-in-calories-out debate loses relevance. Justin believes that the quality of what you eat trumps quantity, especially when the standard American diet is full of ultra-processed, nutrient-depleted products masquerading as food.

He even created a nutrient-dense baby formula from whole foods in his kitchen—one that performed better than the hospital’s ketogenic formula. That formula became the basis of Clovis, his real-food nutrition company.

Building Clovis: A Cult of Care, Not Calories

Today, Clovis has helped thousands of people—many of them women—reclaim their health through real food. Ironically, though Justin started out as a guy chasing six-pack abs, 85% of his clients are middle-aged women. Why?

Because he listens. And he doesn’t blame them.

Most of Justin’s clients came to Clovis because they were tired of being gaslit by doctors and trainers who told them they were either lazy or lying about what they ate. Instead of shaming them, Justin offered support, clarity, and empowerment.

His success isn’t about being right—it’s about being real.

The Science Bias: Why Women Are Left Behind

Justin also highlights a little-known truth: most health and fitness research is conducted on college-aged men. That means women—especially those going through hormonal shifts like pregnancy or menopause—are following advice never meant for them. From intermittent fasting to cold plunges, a lot of what’s marketed as “optimal” health just doesn’t work the same way for women.

His solution? Bioindividuality. Treat the person, not the protocol. Especially when it comes to women’s unique physiology.

Fighting Body Image Lies in the Age of Instagram

Justin doesn’t hold back when it comes to calling out the fitness industry. Social media, he says, has warped our sense of what healthy even looks like. We’re bombarded with Photoshopped influencers, steroid-built physiques, and “infertile six-packs”—men who look superhuman but can’t function without hormone therapy.

Health, he argues, has been replaced by aesthetic perfection—and it’s discouraging real people from even starting.

One Simple Rule for Better Nutrition

If you’re overwhelmed by conflicting health advice, Justin has a refreshingly simple tip:
Follow the One Ingredient Rule.

If a food has only one ingredient (like “apple” or “beef”), it’s probably real food. If it has a list of chemicals you can’t pronounce, it’s probably poison.

Start there, and you’re already ahead of most of the population.



Final Thoughts

Justin’s story is more than a wellness transformation—it’s a reminder that health isn’t about extremes, shame, or fitting a mold. It’s about choosing real food, listening to your body, and refusing to settle for the toxic norm.

Whether you’re a fitness junkie, a frustrated dieter, or just someone who wants to feel better in their skin, the message is clear: Food can heal—or harm. Choose wisely.
