Science & Chill

In this episode of Science & Chill, I interview ultra-endurance runner Zach Bitter.

Zach is the previous world record holder in the 12-hour run on the track and the 100-mile run on the track (which he actually ran in the same race). He also holds the world record for the fastest 100 miles run on the treadmill. In this episode we talk about these records and put them into perspective, so you all will get an idea of how fast he is running these insane distances. 

Zach is also a fascinating guy because he is interested in the nuances of metabolic health and performance. He is famously known as the “low carb endurance runner” in nutrition and running circles. Through his appearance on the Joe Rogan podcast and affiliation with the carnivore doctor Shawn Baker, Zach has gained a reputation as someone who thrives on a low carbohydrate diet. This is the main thing I wanted to talk to Zach about — what he actually eats, how he structures nutrition and thinks about fueling, and some of the nuances surrounding low-carb diets when it comes to optimal human performance.

In this episode of Physiology Friday, I discuss a study investigating whether 8 weeks of time-restricted eating added to a strength and aerobic exercise training program could enhance fat loss and improve cardiometabolic biomarkers to a greater extent than a normal eating regimen.

In this episode of the podcast, I interview Dr. Brittany Allman.

Dr. Allman is a postdoctoral researcher at the University of Arkansas for Medical Sciences, where her areas of research include the maternal programming of obesity — how a mother’s health can influence the metabolic health of her offspring. She also is interested in the effect of obesity on mother and child health outcomes. Another promising area in which Dr. Allman is researching is exercise during pregnancy, and this was the main reason I wanted to interview her. We discuss the safety of exercise during pregnancy, the beneficial effects that exercise can exert throughout pregnancy on a mother’s health, and some fascinating science related to how exercise can influence the health of the baby through epigenetic and other types of metabolic and fetal programming.

In this episode of the Science & Chill podcast, I interview Dr. David Church.

Dr. Church is a postdoctoral researcher at the University of Arkansas for Medical Sciences, where his work involves many topics but primarily a focus on using stable isotope tracers to understand protein metabolism within the body. As you’ll hear in the episode, Dr. Church has an extensive training background in physiology; from strength and conditioning and sports science to specific pathways involved in muscle signaling. We cover many of these topics in this interview. We cover some of the basics around protein — what are amino acids, what is muscle protein synthesis, and what influences whether we build up or break down muscle? David even touches upon some long-held myths surrounding protein like the optimal dose and whether the “anabolic window” really exists. 

We also discuss muscle catabolism — what happens to skeletal muscle when the body is in a state of extreme stress; things like aging, extreme burn injury, and sustained military operations. Dr. Church recently published a paper discussing potential countermeasures that military and other organizations may be able to make use of to prevent muscle breakdown in states of extreme metabolic stress.
