And so once I saw that, I was like, wow, there's something here.

So I had all of these blood samples stored and I started looking at hormones in the blood that related to acutely to our appetite regulation.

And I found that the hormone grelin, which is the hunger hormone, was significantly lower in

Hello, my betties.

Welcome back to another episode of Better with Dr. Stephanie.

It's me, your host, Dr. Stephanie Estima.

Today we are talking all about aging well, muscle recovery, muscle potentiation, performance, and cognitive ability.

My guest today is Brianna Stubbs.

She is the Director of Translational Science

at the Buck Institute for Research on Aging,

where she leads efforts to translate ketone body research

into interventions that promote healthy aging.

In 2004, at the age of 12,

she became the youngest person to row across the English channel. Dr. Stubbs

earned her PhD in metabolic physiology from the University of Oxford, focusing on the metabolism

and application of exogenous ketone, salts, and esters. While completing her study, she competed

on the British international rowing team, becoming a two-time world champion,

lightweight athlete. And prior to her role at the Buck Institute, she serves as research lead
