Brittany Johnson PhD - What GLP-1 Drugs Really Do To Appetite, Muscle, And Long-Term Weight

2026-07-0924:35

GLP-1 drugs are changing the weight loss landscape fast, but the most important questions aren’t about hype, they’re about outcomes. We sit down with Dr. Brittany Johnson, a registered dietitian-nutritionist and PhD scientist, to explain what GLP-1 medications actually do in the body: appetite suppression, slower gastric emptying, and improved blood sugar control, plus why people often talk about Ozempic when they really mean a broader class of medications. We also dig into semaglutide vs tir...

Katie Vasenina PhD and Brandi Antonio MS Skewer Silly New Year's Resolutions

2025-12-2322:02

We skewer extreme New Year’s resolutions and swap them for simple, sustainable habits that actually build fitness. From 75 Hard to detoxes and no-days-off myths, we cut through noise and focus on recovery, progression, and realistic goals. • Why 75 Hard and streaks fail on sustainability and purpose • Why coffee and moderate caffeine can support health and training • how to build from 5K consistency before marathons and Ironman • the role of recovery, easy sessions, and strength work • why d...

Episode 101 - Small Buffers, Big Edge with Eli Shannon PhD

2025-12-0434:20

Ever wonder how a legal buffer can shave nearly a minute off a 40K time trial? We sit down with freshly minted PhD Eli Shannon to unpack the science and the tactics behind sodium bicarbonate, from the lab to the start line. Eli explains why an hour-long ride is anything but steady state and how surges, climbs, and late-race kicks amplify the value of buffering hydrogen ions when it matters most. We dig into the numbers: an average 1.4% improvement for trained male cyclists, translating to ab...

Episode 100 - Sit In A Tub, Run Like A Rocket with PhD Student, Elliott Jenkins

2025-11-2634:00

We talk with physiologist Elliot Jenkins about how passive heat acclimation boosts VO2 max, hemoglobin mass, and cardiac function in trained runners without adding mechanical training load. Practical protocols, safety tips, and open research questions round out a clear, actionable guide to using heat wisely. • Elliot’s path from Otago to a PhD in the UK • Why passive heat instead of exercising in heat • Hematology: plasma volume expansion • Cardiac changes: larger end-diastolic volume ...
