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.

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

How long to consume SIBO Yogurt?
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-sourced microbes that colonize the small intestine and produce natural antibiotics effective in killing the species of SIBO, a strategy that has been exceptionally effective.But how long should you consume SIBO Yogurt to confidently correct this situation?Support the showYouTube channel: https://www.youtube.com/@WilliamDavisMD Blog: WilliamDavisMD.com Membership website for two-way Zoom group meetings: InnerCircle.DrDavisInfiniteHealth.com Books: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed

Why it's crucial to keep triglycerides at 60 mg/dl or less
Triglycerides play a crucial role in heart health, yet they are often overlooked in favor of LDL cholesterol. Keeping triglyceride levels at 60 mg/dL or less can drastically reduce health risks. The podcast dives into how unhealthy carbohydrates contribute to triglyceride production in the liver. Natural dietary strategies, including cutting out grains and sugars, along with supplementing with omega-3s, can help achieve this goal. Listeners also discover the connection between gut health, endotoxins, and liver function.

What do I mean by "Super Body"?
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 factors largely absent from the modern health experience, effects you can track using a variety of methods: biomarkers, grip strength, visceral fat measurement, for example.

Amylopectin A: Demon Carbohydrate
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.

Why Losing Weight the Wrong Way Can Be Dangerous
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 compensate and specifically target the most unhealthy forms of body fat, restore youthful muscle, restore basal metabolic rate and thereby absolve yourself of these unhealthy outcomes. You can find a full discussion of these strategies in my new Super Body book:https://www.amazon.com/SUPER-Body-Composition-Youthful-Contours/dp/0306835991Support the showYouTube channel: https://www.youtube.com/@WilliamDavisMD Blog: WilliamDavisMD.com Membership website for two-way Zoom group meetings: InnerCircle.DrDavisInfiniteHealth.com Books: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed

What'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?

Pushback against GLP-1 agonists
The discussion dives into the risks of GLP-1 agonist drugs, highlighting immediate side effects and dire long-term consequences like frailty and early mortality. Weight loss from these drugs often leads to muscle loss, impacting metabolism negatively. The conversation critiques conventional dieting approaches, suggesting they have fueled the obesity crisis. Instead, there's a focus on managing body composition and returning to ancestral dietary patterns for better health outcomes. Strategies to shed visceral fat while preserving muscle are emphasized.
