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' intention. Among the topics the Defiant Health Podcast covers are:--Microbiome health--The key to so many health conditions, as well as preservation of youth and vigor, can be found in the microbiome.--Heart health--You will find no mention of cholesterol or statin drugs here, only hard-hitting, science-based insights.--Thyroid health--Why do endocrinologists and other doctors get thyroid health so wrong? Let's get it right.--Weight loss--We don't count calories, don't push the plate away, or echo other ineffective knuckle headed solutions that have created the most overweight population of humans in history.--How to get rid of type 2 diabetes--it's painfully easy. --Get on the road to reversing autoimmune diseases--Take steps today to prevent neurodegenerative diseases such as Alzheimer's dementia, Parkinsonism, and multiple sclerosis--And many others.For more information on Dr. Davis' insights and programs, seeWheat Belly books--esp. the Wheat Belly Revised & Expanded Edition, 2019Wheat Belly 30-Minute CookbookWheat Belly 10-Day Grain DetoxUndoctored: Why Health Care Has Failed You and How You Can Become Smarter Than Your DoctorWheat Belly Blog: www.wheatbellyblog.comTalk to me through my membership website, the Undoctored Inner Circle:InnerCircle.Undoctored.com
- 16 minutes 43 secondsWhat's the REAL story with fish oil?
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 cardiovascular risk--even facilitate regression--and dementia.YouTube channel: https://www.youtube.com/@WilliamDavisMD

4 December 2025, 11:00 pm - 17 minutes 26 secondsWhat's better than probiotics?
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. Then let’s discuss how you can do better than taking some random commercial probiotic off the shelf.

10 November 2025, 4:00 pm - 11 minutes 35 secondsPushback against GLP-1 agonists
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.YouTube channel: https://www.youtube.com/@WilliamDavisMD

5 November 2025, 6:00 pm - 8 minutes 12 secondsWhy Weight Loss Can Be Harmful to Your Health
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 concepts that block these effects, concepts that I shall be exploring in even greater depth in my new book, Super Body.

Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight
22 October 2025, 5:00 pm - 13 minutes 52 secondsOxalate Hysteria
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 primary problem, just a Band-Aid.
Oxalate hyperabsorption is due to disruption of the gastrointestinal microbiome: loss of the many species that metabolize oxalates but were eliminated or reduced due to antibiotic exposure, and the development of small intestinal bacterial overgrowth, SIBO, that is associated with abnormally increased oxalate absorption. Address the disrupted gastrointestinal and dietary oxalate consumption is no longer an issue for the vast majority of people.
In this episode of the Defiant Health podcast, let’s discuss why so many people have been misled by this dietary oxalate issue and a smarter way to deal with what might be interpreted as oxalate intolerance.

15 October 2025, 11:00 pm - 28 minutes 39 secondsWhat happens when you deprive yourself of blue light?
Science journalist Lynne 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 health and performance. After these sorts of unique experiences, along with discussions on circadian rhythms with numerous scientists working on this topic, Lynne comes to some unique conclusions.
Lynne is the author of the book “The Inner Clock: Living in Sync with Our Circadian Rhythms” in which she explores the role of purposeful management of your circadian rhythm, your inner clock, for management of energy, focus, and mood. Here, Lynne and I talk about her novel insights, along with practical advice on how to better manage your light exposure and circadian rhythm.

24 September 2025, 11:00 pm - 12 minutes 50 secondsWhy are you no longer hungry?
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, nonsensical dietary advice, and a disrupted gastrointestinal microbiome.

Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight
17 September 2025, 1:00 am - 18 minutes 2 secondsThere's a 50:50 chance that you have this epidemic condition
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 from the colon yield a phenomenon called "endotoxemia," or the entry of bacterial breakdown products into the bloodstream. This is how a disrupted small intestinal microbiome can be experienced as depression, anxiety, neurodegenerative disorders like dementia; heart problems such as coronary disease, atrial fibrillation, and congestive heart failure; skin issues such as as rosacea and psoriasis; muscle and joint issues such as fibromyalgia; gastrointestinal issues such as irritable bowel syndrome and Crohn's disease.
Understand how to recognize this process and manage it and you have been given a huge advantage in regaining control over health.YouTube channel: https://www.youtube.com/@WilliamDavisMD

Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight
9 September 2025, 1:00 pm - 10 minutes 28 secondsHere's a microbe you should know about: Bacillus subtilis
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 therefore replaced it with B. subtilis, a virtual powerhouse of a bacteriocin producer, producing up to 7 bacteriocins, thereby giving you greater power in pushing back invading fecal microbes in SIBO.
So in this episode of the Defiant Health podcast, let me get you acquainted with this powerful microbe that, I believe, can provide major advantages in your efforts to take back control over gastrointestinal and overall health.

3 September 2025, 4:00 pm - 18 minutes 59 secondsYogurt That's Not Yogurt: My Accidental Sleep Cure
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 and, if they did not work, I was often left irritable and fatigued.
All this changed when I began experimenting with microbiome strategies. It’s become clear that the gut microbiome plays a major role in determining the quality, length, and content of your sleep. An outsized role is played, however, by the phenomenon of endotoxemia, the entry of bacterial breakdown products into the bloodstream and that is the topic I’d like to focus on in this episode of the Defiant Health podcast. The experience is so preliminary that it has not yet been validated in clinical studies. But if the solution is as easy, inexpensive, and accessible as something that looks and smells like yogurt (it’s NOT yogurt, of course), then why not give it a try? You may be among the roughly 50% of people who experience dramatic improvements in the duration and quality of your sleep.
