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...

Why is cholesterol testing not dead yet? 03.07.2026 16:51
Why are we still using 1950s technology to predict and manage risk for heart disease in the form of cholesterol testing? Superior methods have been available for >30 years. Sadly, the key is money. If superior methods to identify and manage risk for heart disease are essentially without cost, how would the healthcare industry make its money?

Why does curing type 2 diabetes remain a secret? 24.06.2026 20:01
I find it shocking that, as easy as type 2 diabetes is to reverse, backed up by even human clinical trials validating this concept, few doctors inform their diabetic patients of this. Oddly, now that GLP-1 agonist (disastrous) drugs are available, the reduction in blood sugar coupled with weight loss has brought the idea of type 2 diabetes remission to the forefront, since it now is profitable t...

"I have a 'cheat' day once per week--Is that okay" 20.05.2026 12:09
If you are trying to eradicate one of the REAL causes of risk for heart disease, small dense LDL particles, is a once-per-week "cheat" day allowable? Can you get away with it by exercising more the following day, or being extra strict? No. Unfortunately, small dense LDL particles are unforgiving and persist for an unusually long period in the bloodstream, thereby adding to risk for card...
Understand the "Universe" of Small Dense LDL Particles 14.05.2026 12:54
Why does much of the world cling to the outdated notion that cholesterol is the cause of heart disease and that reducing cholesterol is the solution, even after decades of evidence have more than amply demonstrated that this approach is woefully inadequate? Sadly, it's about money. But you do not have to be hogtied by financial concerns. You can take a path that actually works. You can start...
Infertility, Miscarriage, Premature delivery: The Crucial Role of Endotoxemia 04.05.2026 15:18
The evolving science has become overwhelming: Lipopolysaccharide endotoxemia, i.e., the entry of bacterial breakdown products into the bloodstream, is a major driver of multiple problems in female reproductive health. Unfortunately, this crucial factor is almost never addressed in conventional healthcare settings. Thankfully, there are steps YOU can take personally to address this important healt...
"Why do I have food intolerances? 24.04.2026 20:53
Food intolerances are growing and more and more people are unable to eat FODMAPs-containing foods, histamine-containing foods, nightshades, legumes, fructose-containing foods and numerous others, sometimes reduced to consuming only a handful of "safe" foods. Why is this happening, something that was virtually unknown only a generation or two ago? Much of it is due to the excessive proli...
Why Life is Better Without Wheat 15.04.2026 14:58
If you are given the kindergarten version of a healthy diet, well, you can expect mediocre results at best, disastrous results at worst. Why not graduate to a higher level of dietary understanding? But don't count on obtaining such insights from conventional sources. Here are some cold, hard facts about the consumption of wheat and grains that everyone should be aware of. Support the show Y...
Understanding the Microbiome: Endotoxemia and Translocation 07.04.2026 17:45
They are somewhat more advanced concepts, but the microbial phenomena of endotoxemia and translocation are proving to be critical processes in initiating or worsening a long list of human health conditions. Because most mainstream doctors have abdicated their responsibility in providing advice to maintaining or regaining health, it is up to YOU to understand these important concepts. Here is a ba...
What is gluten and why you should avoid it 29.03.2026 19:11
Despite my Wheat Belly series of books having been read by millions of people in nearly 40 countries, many people still think that a grain-based diet is healthy. Many also confuse this message with being "gluten-free." Let's think about this issue more clearly so that you understand the power you have in your hands to assume control over health and weight by being smarter and better...

Why is grain elimination good for oral health? 16.03.2026 18:26
Scientific insights into the oral microbiome are yielding many new lessons for dental health: mouthwashes are actually dangerous, fluoridated drinking water does not prevent cavities, some toothpastes contain harmful additives. But the most important factor for dental health is often neglected: the role of eliminating grains. The amylopectin A of grains is a major factor in degrading dental healt...

Does dementia start in the mouth? 03.03.2026 12:52
A number of studies in which the brain tissue of people who have died of dementia have revealed the presence of microbial species such as Porphyromonas gingivalis, Fusobacterium nucleatum, and Tannerella forsythia--all oral microbes. This is an example of translocation, i.e., the migration of microbes from one body site to another. But does this cause or accelerate dementia? This remains an unsett...
It's Not Yogurt 23.02.2026 12:02
We've been fermenting HUMAN-SOURCED microbes to generate very high microbial counts and obtain specific health benefits. The end-result looks and smells sort of like conventional yogurt, but it is NOT yogurt. (I called it "yogurt" for lack of a better term.) It's my way of generating high counts of important microbes that most people have lost due to antibiotics and other facto...
Why You Should NOT Measure Apoprotein B 21.02.2026 13:12
Apoprotein B provides a virtual count of the lipoprotein particles in the bloodstream that cause coronary heart disease. It is often held up as superior to the widely used LDL cholesterol value. Is this true? It is true, but it does not mean that measuring apoprotein B tells you much about health. Compare this to the enormous amount of insight provided by measuring the REAL cause of heart disease:...
What's all this about making "yogurt"? 12.02.2026 7:18
Why has yogurt making gone viral? First of all, it's NOT yogurt. It looks and smells like yogurt. By FDA regulations, something called yogurt must be fermented with traditional yogurt-making microbes Lactobacillus bulgaricus and Streptococcus thermophilus . That's NOT what we are doing. Instead, we are fermenting human microbes, i.e., microbes that are adapted to the human body and provi...
Are microplastics the newest cardiovascular risk factor? 05.02.2026 14:16
The evidence is growing that suggest that microplastics, or more specifically smaller nanoplastics, are triggers for atherosclerotic disease with increased risk for heart attack, stroke, and death. While your doctor wastes your time and money obsessing about cholesterol and statin drugs that should have been discarded decades ago, you need to address the REAL factors that cause heart disease. Add...
Reduce and track abdominal visceral fat for improved health 29.01.2026 16:51
Abdominal visceral fat, i.e., fat within the abdominal cavity that surrounds abdominal organs, is unique and the source of so many common health problems. While people who are overweight with a protuberant abdomen almost always have an excess of abdomen visceral fat, it can also occur with a flat abdomen. You can reduce and track the amount of abdominal visceral fat with home bioimpedance devices...
The Crime Called Type 2 Diabetes 24.01.2026 18:24
The crime is not having type 2 diabetes. The crime is that conventional forces in healthcare essentially turn a blind eye to all the ways available to NOT be a type 2 diabetic. Pharmaceutical executives throw lavish parties to celebrate the huge revenues that derive from diabetes drugs that now include the awful GLP-1 agonists, while almost no one in healthcare shows people how to not be diabetic...
How long to consume SIBO Yogurt? 21.01.2026 10:25
SIBO (small intestinal bacterial overgrowth) is now epidemic in the U.S., affecting around 50% of the population. It is responsible for an impressive range of health conditions from obesity, to type 2 diabetes, to irritable bowel syndrome, to fibromyalgia and numerous others. We have been addressing SIBO with a collection of microbes that I call "SIBO Yogurt," a collection of human-sourc...
Why it's crucial to keep triglycerides at 60 mg/dl or less 20.01.2026 17:36
There's one truly helpful value on a standard cholesterol panel: triglycerides. Ironically, it's also the value most likely to be ignored or mismanaged because the doctor wastes your time by focusing on the useless total and LDL cholesterol values, having been brainwashed by the flawed science and pharmaceutical marketing. Here is WHY triglycerides are so important, HOW you can reduce y...
What do I mean by "Super Body"? 13.01.2026 8:57
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...
Lessons Learned From 30+ Years of CT Heart Scans and Coronary Calcium Scores: The Critical Role of Vitamin D 09.01.2026 19:02
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 actu...
Amylopectin A: Demon Carbohydrate 04.01.2026 10:07
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 wha...
