The future of exercise
The Future of Everything
Intro
Exploring the potential of mimicking exercise benefits through therapeutics for older individuals, focusing on combating obesity and diabetes epidemics by understanding exercise pathways and the release of body chemicals pre and post-exercise.
Jonathan Long is a biochemist who studies the chemicals produced during exercise. In Long’s world, “you always start with molecules,” which offer “clean handles” to understanding complex processes. His lab has identified a chemical produced in the digestive tract during exercise that can make a person stop eating. Long now studies this “gut-brain axis” for ways to treat obesity, diabetes, and, perhaps, even age-related conditions like dementia, as he tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.
