Episode Details

Frailty isn’t just something that happens “later”; it’s a gradual loss of resilience that can begin much earlier than most people think. Katy Bowman and Dr. Jeannette Loram unpack what frailty and pre-frailty mean biologically. They explore the five key hallmarks used to identify frailty, including walking speed and grip strength, and how a large proportion of people in their 30s and 40s already fall on the spectrum of pre-frailty.

The conversation also explores the muscle–gut connection, explaining how frailty is influenced by exercise, diet, and the health of your microbiome. Katy and Jeannette also discuss the potential for rapid-onset frailty linked to the use of GLP-1 medications.

Most importantly, frailty can be reversed and this episode focuses on what you can do. From simple ways to improve resilience through movement, nutrition, and rest, to understanding how your attitude toward aging might influence your resilience
