S2 EPISODE 44 - Athletes, Exercise Immunology & Immuno-Nutrition w/ Dr. David Pyne PhD

Season 2 Episode 44, Dr. Bubbs interviews expert physiologist Dr. David Pyne PhD to talk exercise immunology and keeping athletes cold and flu free. In this episode, Dr. Pyne reviews the fundamentals of immunology and how the immune system is regulated by exercise and nutrition. He’ll discuss how training volume, intensity and load impact immunity, and more importantly, why keeping athletes cold and flu free is paramount for athletic success. Dr. Pyne also discusses the key immunity biomarkers and how effective they may (or may not) be at flagging at-risk athletes. Finally, he dives into the topic of immune-nutrition and how the food you eat, and supplements like probiotics, can impact athlete immunity and therefore ability to train and compete.

S2 EPISODE 29 - The Microbiome, Gut-Brain Axis & How To Build A Healthy Gut w/ Miguel Mateas PhD(c)

In season 2 Episode 29, Dr. Bubbs interviews Miguel Mateas PhD(c) to talk about the gut microbiome and the implications on the gut-brain axis. In this episode, Miguel discusses the dynamic ecosystem that makes up the gut, how specific bacteria are attracted to certain conditions and the impact of processed food on the gut microbiota, as well as how exercise impacts gut microbial diversity (including new research on how the mindset may play a role), and then dives into the many ways the gut microbiota communicates with the brain and implications for health and performance. Great insights and metaphors to explain complex topics from Miguel!

Lay-Ups In This Episode

1)    Dysbiosis is an imbalance between the “good” and “bad” bacteria of the gut.

2)    The gut communicates to the brain via the vagus nerve, tryptophan, butyrate and many other signals from the digestive system.

3)    Gut diversity is the most reliable biomarker for health.

S2 EPISODE 4 - Zero-Carb Carnivore Diet, Health and Performance w/ Dr. Shawn Baker MD

In Season 2 Episode 4, Dr. Bubbs chats with Dr. Shawn Baker MD, an orthopedic surgeon, former competitive athlete and a man following an all-meat diet.

Lay-Ups

  1. A carnivore diet is an entirely meat only diet.
  2. In the early 1900s, explorer Vilmur Steffanson undertook a study of eating nothing but meat for an entire year. They completed the study in perfect health.
  3. Any diet that completely excludes processed foods is likely to yield positive gains (and a caloric deficit).

Performance Tips

  1. Athletes with larger neck circumference – American football and rugby – are much more prone to sleep apnea.
  2. The older you get, the worse your blood sugar control (compared to younger athletes).
  3. You can break world records at 50 eating nothing but meat!

The “Big Rocks” – Shawn’s Tip

Make sure your portions sizes are big enough!
