Dr. Jockers Functional Nutrition

In this episode, Dr. David Jockers sits down with Vanessa Spina, sports nutrition specialist, bestselling author of Keto Essentials, creator of the Tone ketone breath analyzer, and host of the Optimal Protein Podcast, for a deep dive on a groundbreaking new study out of the University of Nottingham, published in Clinical Nutrition in August 2025.


You will learn why the old "you can only absorb 30 grams of protein per meal" rule doesn't hold up, what really happens to protein you eat beyond that amount, and why the popular anabolic-window advice to slam a shake right after your workout is largely a myth. Dr. Jockers and Vanessa then break down a randomized, controlled fasting-mimicking diet study that overturns the long-held belief that high protein blocks autophagy, and explain why a high-protein, calorie-restricted approach can outperform a low-protein one for visceral fat loss, ketone production, and metabolic health. 

They close with a practical, hour-by-hour walkthrough of the protein-sparing modified fast (PSMF): what to eat, how much protein to target, how to structure refeed days, and how it compares to water fasting and Ozempic for appetite control.

In this episode, Dr. David Jockers breaks down fasting as the most powerful natural anti-inflammatory tool available, walking through a detailed hour-by-hour timeline of what happens inside your body, from the first 12-hour gut and liver reset all the way out to the deep cellular healing of a 3-to-5-day fast.


You will learn exactly what your body is doing at each checkpoint of a fast, from the metabolic switch into fat burning at 14 hours, through the onset of autophagy and BDNF-driven mental clarity, to the dramatic rise in human growth hormone at 24 hours, the gut microbiome shift at 36 hours, and the full immune system rejuvenation that unfolds between 48 and 72 hours. Dr. Jockers also lays out a practical, step-by-step way to build up to longer fasts safely.

In this episode, Dr. David Jockers goes solo to break down five of the most common health myths he hears on a regular basis, the ones most people you know believe and are unknowingly putting into practice against their own health.


You will learn why sunshine isn't the enemy your dermatologist made it out to be, why skipping breakfast can be one of the healthiest things you do, why saturated fat and cholesterol aren't driving your heart disease risk, why a low-salt diet might be working against you, and why a high-protein diet isn't damaging your kidneys, plus the real, evidence-backed root causes behind each of these conditions.

In this episode, Dr. David Jockers is joined by his longtime friend Dr. Josh Axe, co-founder and chief visionary officer of Ancient Nutrition, founder of draxe.com, and founder of The Health Institute, for a deep dive into cellular longevity.
 
You will learn why some organs age faster than others, what's really happening inside your cell membranes and mitochondria as you get older, and which foods, from super berries and pomegranates to organ meats, healthy fats, fermented foods, and longevity mushrooms, do the most to slow that process down.
 
Dr. Axe and Dr. Jockers also break down his top longevity supplements, including vitamin D, soil-based probiotics, omega-3s, magnesium, and NAD/NMN, why quality matters so much more than quantity when it comes to supplements, and the surprising role of the gut microbiome, bee products, and daily herbal tea in living a longer, more vibrant life.
