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?

Why 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. **Disclaimer:**The information presented in my books, blog posts, YouTube videos, podcasts, and other content is for informational and educational purposes only.

Oxalate 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.

What 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.
