Defiant Health Radio with Dr. William Davis

William Davis, MD

William Davis, MD, cardiologist and author of the #1 New York Times bestselling Wheat Belly books, as well as Undoctored and, most recently, Super Gut, brings the unvarnished truth about many health conditions. So much information in health is crafted by industry, bent to the benefit of healthcare systems, delivered by willfully ignorant physicians. Yet a critical mass of truly useful, safe, effective health information has been reached--but someone has to deliver it to you. That is Dr. Davis"

What do I mean by "Super Body"?

Defiant Health Radio with Dr. William Davis ·

2026/01/13

It's not about having the build of a bodybuilder, nor 6-pack abs, or bulging biceps. It's about having optimal metabolic health that stacks the odds in favor of being free of heart disease, risk for cognitive impairment, cancer, loss of independence and other health conditions. We therefore work to reduce or minimize abdominal visceral fat while restoring youthful musculature. We do so starting with unique methods to restore a healthy gastrointestinal microbiome, then restore other fac...

Lessons Learned From 30+ Years of CT Heart Scans and...

Defiant Health Radio with Dr. William Davis ·

2026/01/09

My 30+ years of involvement with CT heart scans and coronary calcium scores has yielded many important lessons on how to halt, then reverse, the accumulation of coronary atherosclerotic plaque and thereby risk for heart attack, need for heart procedures, and sudden cardiac death. Here, I discuss the crucial importance of vitamin D and how, by addressing this issue, it was the first time I saw actual reductions in coronary calcium scores.

Amylopectin A: Demon Carbohydrate

Defiant Health Radio with Dr. William Davis ·

2026/01/04

Amylopectin A is the branching carbohydrate unique to wheat and grains that sends blood sugar through the roof, increases liver production of triglycerides, contributes to risk for heart disease, and accelerates many of the phenomena of aging. Yet we are essentially advised to include sources of this demon carbohydrate in our daily diets. You need to be informed and recognized that so much of what your are told in diet and health is crafted for profit, not your benefit. **Discla...

Why Losing Weight the Wrong Way Can Be Dangerous

Defiant Health Radio with Dr. William Davis ·

2026/01/03

If you lose weight by reducing calories--a diet, bariatric procedure, or pharmaceutical like a GLP-1 agonist--you will indeed lose weight at first. But long-term, unhealthy changes in health will develop: eventual weight regain, increased risk for heart disease, type 2 diabetes, dementia, frailty. And thare are now sufficient data to tell us that you also cut your life short by several years. The key: NEVER engage in any of these methods. If you have, there are steps you can take to co...

What's the REAL story with fish oil?

Defiant Health Radio with Dr. William Davis ·

2025/12/04

Nearly 30 years of misinformation, disinformation, and misleading marketing have left most people confused: Do omega-3 fatty acids from fish oil reduce cardiovascular risk, dementia, and other conditions? Or are there adverse effects to expect, or greater benefits from other products? Let's cut through 30 years of imprecise thinking and get to the bottom of this question. Final conclusion: Omega-3 fatty acids are among the most important components of diet you can consume to reduce both card...

What's better than probiotics?

Defiant Health Radio with Dr. William Davis ·

2025/12/01

Many people take probiotics in the hopes that it will help reduce gastrointestinal struggles with excessive gas, bloating, diarrhea, constipation and other common complaints. Sometimes they help, sometimes they don’t. But why? Just what are probiotics and how are they created? In this episode of the Defiant Health podcast, let’s discuss the ups and downs of commercial probiotics, why they are really little more than haphazard collections of microbes assembled without rhyme or reason.

Pushback against GLP-1 agonists

Defiant Health Radio with Dr. William Davis ·

2025/11/05

Millions of people have been persuaded that the GLP-1 agonist drugs are the answer to their weight loss prayers. While they do work well in the near-term for weight loss, the long-term health price you pay is substantial with a future of increased risk for frailty, loss of independence, and premature death. A better way is to manage the amount and location of muscle and fat, i.e., shape and body composition. And you can do so easily, naturally, and inexpensively. Support the show...

Why Weight Loss Can Be Harmful to Your Health

Defiant Health Radio with Dr. William Davis ·

2025/10/22

Yes, you can lose weight by reducing calories whether through a calorie-cutting diet, bariatric procedure, or pharmaceutical. But the effect is almost always temporary and followed by a return of weight followed by significant downturn in health. You were also likely not advised that losing weight by cutting calories, we now know through tracking of large numbers of people over many years, likely abbreviates your life by several years. In this and future podcasts, I will be introducing...

Oxalate Panic, Debunked

Defiant Health Radio with Dr. William Davis ·

2025/10/15

There are a number of people advocating a diet low in oxalates, essentially eliminating many green leafy vegetables, Brussels sprouts, asparagus, celery, most nuts, berries, cocoa, and numerous otherwise healthy foods. Unfortunately, this advice is misguided and based on an incomplete understanding of the evidence. While there is no harm in reducing dietary oxalates beyond inconvenience, lack of variety, and the absence of many genuinely healthy foods, reducing oxalate exposure is not the pri...

What happens when you deprive yourself of blue light?

2025/09/24

Science journalist Lynn Peeples did something extraordinary: She spent 10 days in a nuclear bunker exposed only to dim red light but no blue or other visible wavelength of light. She also rid the space of all clocks or other time-indicating devices and even avoided having any human contact. What she learned opened up numerous questions on how to best manage our day-to-day light exposure, wavelengths, and the implications they have on the quality of sleep, our moods, even various aspects of he...

Why are you no longer hungry?

2025/09/17

People who were previously ravenously hungry, struggling to be satisfied and tending to overeat, can find themselves miraculously back in control of appetite just by adopting a number of basic dietary strategies that begin with elimination of gliadin-derived opioid peptides that come from the partial digestion of wheat and grains. Add a handful of other strategies and you will be freed from abnormal and perverse appetite stimulation that comes from consumption of several foods, nonsensi...

Defiant Health Radio with Dr. William Davis ·

2025/09/09

There is a non-infectious epidemic occurring right beneath our noses. The likelihood that you are affected is around 50%. It's the epidemic of small intestinal bacterial overgrowth, or SIBO. In this episode of Defiant Health, I run through the rationale that reveals that, even conservatively estimated, more than 100 million Americans have this condition. Because of the natural permeability of the small intestine designed for nutrient absorption, invading fecal microbes that have ascended fro...

2025/09/03

My original recipe for SIBO Yogurt included three microbes chosen for their ability to colonize or germinate in the small intestine and produce bacteriocins, natural peptide antibiotics effective in killing the species of SIBO. The original formulation therefore specified L. reuteri, L. gasseri, and B. coagulans. However, B. coagulans proved to be unreliable in generating the high microbial counts we desire to overcome the trillions of invading fecal microbial species of SIBO. I therefo...

Yogurt That's Not Yogurt: My Accidental Sleep Cure

2025/08/29

I’ve personally struggled with insomnia for years, unable to sleep more than a few hours at a time, experiencing frequent awakenings, sometimes awakening at 3 or 4 in the morning and unable to get back to sleep. And I tried almost everything short of prescription sedatives: tryptophan, 5-HTP, megadose melatonin, GABA, theanine, the antihistamine diphenhydramine, self-hypnosis, YouTube videos that claim to help you sleep within minutes. The few that worked left me feeling drugged the next day ...

You’re walking down the street, minding your own business, just out to run some errands. You’re wearing a black jacket, running shoes, a baseball cap. You pass the doors of a bank. Suddenly, the bank’s doors fly open and a man runs out, a man wearing a black jacket and a baseball cap. You see him running at top speed, disappearing around a corner. Moments later, two policemen burst through the bank’s doors, spot you, roughly spin you around, handcuff and arrest you. It’s a clear case of...

It seems that a day doesn’t pass without some new, interesting insight emerges on microbiome questions, providing us with unprecedented insights and strategies to get better control over health, weight management, aging, etc. Look at what we are accomplishing, for example, with our cultivation of L. reuteri and L. crispatus.

What was this Wheat Belly thing all about?

Millions of copies of the book were sold in 37 countries, the conversation was featured in major media from network news to Dr. Oz to . I don’t believe that this was due to my personal charm or charisma, but because it worked: people experienced unexpected and substantial health and weight loss benefits even if such things had eluded them for years.

While CT heart scans are becoming increasingly popular to generate a coronary calcium score as a gauge of coronary atherosclerotic plaque and thereby risk for heart attack, there is actually a treasure trove of other useful information provided by the scan—but often not reported to you. In this episode of the Defiant Health podcast, I therefore help make you aware of the wealth of information provided by a CT heart scan that can empower you further in maintaining health and preventing h...

Defiant Health Radio with Dr. William Davis ·

2025/07/07

Inulin is a common fiber, the fiber found in root vegetables like onions, garlic, shallots, asparagus, jicama and many other foods. Humans lack the digestive enzymes, however, for metabolizing inulin, but microbes living in your gastrointestinal track are able to metabolize it. When beneficial microbes metabolize inulin, they convert it to fatty acids with numerous beneficial effects on gastrointestinal, brain, and metabolic health. But, when undesirable microbes metabolize inulin, bad things...
