Skeletal muscle is the biggest oversight I believe in medicine today. Skeletal muscle is the organ

of longevity. The health of skeletal muscle trumps the idea of body fat any day of the week.

There is this beautiful interface between the health of the skeletal muscle and the action

that skeletal muscle is meant to play in our life and subsequent outcomes, all the diseases

that we relate to metabolic health at its root, beginning skeletal muscle first, decades before.

So, modern life, the way so many of us work in life, has been largely devastating to the physical

well-being of so many people. It's implicated in record levels of chronic inflammation, pain,

illness, limitation, diabetes, obesity, and overweight, metabolic dysfunction,

and many potentially life-threatening or limiting diseases. And the medical community and

a massive commercial industry often points a finger at body composition, in particular the

percentage of fat that we carry as one of, if not the main contributor, to so many of these

risk factors and conditions and focuses on treating that. But what if they're getting it wildly

wrong? What if there was something else, something we rarely talk about that was a true or more

sustainable remedy. Something that was available to all of us and that not only held the potential

to turbocharger metabolism, immunity, brain function, physical capability, and mental agility

and improved mental health. And it was entirely free. According to today's guest, Dr. Gabrielle

Lyon, a renowned physician and researcher, we are missing something huge. She's dedicated her

career to understanding the overlooked importance of skeletal muscle for metabolism, immune function,

disease prevention, and more. And in our conversation, she reveals how loss of muscle mass,

as we age not fat accumulation, is secretly one of the biggest things that undermines our health

and longevity in ways we don't think about or realize. Dr. Lyon completed her medical training

and a fellowship in geriatrics and nutritional sciences at Washington University in St. Louis
