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?

How to use inulin to map the location of microbes in your GI tract
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 can happen and cause you to experience symptoms such as excessive bloating, abdominal discomfort, diarrhea, mental effects such as anxiety, depression, suicidal thoughts, worsening joint pain or skin rashes. The difference is all about location of these microbes, where they are located in the 30-feet of your gastrointestinal tract. In this episode of the Defiant Health podcast, Let’s therefore discuss how to use the common fiber inulin to map where such microbes are living in your GI tract and, should you determine that undesirable species are living where they don’t belong, what you can do about it.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

Hyaluronic acid: Most important DIETARY fiber of all?
We’ve been urged to include plenty of dietary fiber in our daily routines, fibers that come from vegetables, legumes, grains and other plant sources. But there is an animal-sourced fiber that has nearly disappeared from the modern human diet: hyaluronic acid. Hyluronic acid has nearly disappeared from the diet because it is primarily sourced from animal products, especially organ meats like brain, skin, and tongue. But hyaluronic acid is a fiber crucial for the health of many human organs: skin, joints, uterus, cervix, vagina, arteries. It is also a fiber with significant benefits on the gastrointestinal microbiome that, in turn, yields substantial benefits via microbial metabolites. In this episode of the Defiant Health podcast, let’s discuss the role of this important fiber and how to bring it back into your lifestyle to obtain its many benefits._________________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here.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

Will eating yogurt change your life?
Go to any supermarket and you will see the impressive variety of products in the dairy aisle labeled "yogurt." You have a mindboggling collection of choices: non-fat, low-fat, full-fat, flavored, unflavored. Single-serve cartons, quart containers, squeezable tubes, jars. Will consuming any of these products change your life in any significant way? Will you be heathier, have better bowel health, skin health, metabolic health, mental health? Let’s discuss why, no, you will not experience any dramatic life-altering effects from consuming these products. They may be tasty, but they will not change your life in any meaningful way. But, by modifying what we call yogurt, you CAN create something that looks and smells like yogurt but DOES provide substantial life- and health-changing effects. __________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here._____________________________________________________________________________MyReuteri and Gut to Glow can be found here: oxiceutics.comSupport 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

The concept of 'autonomic conflict' complicates matters further, as both nervous system branches engage simultaneously. Litigation is on the rise due to sudden cardiac incidents linked to this practice. Safer alternatives, such as progressive cold showering, are recommended for those seeking similar benefits without the associated risks.

Why Cutting Calories is Dangerous
Over 50% of Americans are, at any one time, trying to lose weight. So it’s understandable that the GLP-1 agonist drugs like Ozempic and Mounjaro have become so popular, given their spectacular upfront results. Others have used reduced calorie diets in their various forms: counting points, assigning foods red, yellow, or green lights, meal replacement products, etc. Or bariatric procedures like lap-band, jejunoileal bypass, or gastric bypass. But there is a lot that people are not told about these methods. The near-term prospect of losing weight is so enticing to people and so profitable to doctors, the healthcare system, and the pharmaceutical industry that is simply no incentive to tell you the full story. So let me fill you in on the real story, the full details about why cutting calories, regardless of the form it takes, can be so dangerous. _________________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here._____________________________________________________________________________MyReuteri and Gut to Glow can be found here: oxiceutics.comSupport 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
