Muscle Is the Key to Longevity (Not Fat Loss) | Dr. Gabrielle Lyon

It's amazing to me how ignored this is in medicine, and it's such a critical part of health. We have this epidemic in this country of not only obesity, but sarcopenia. And you put together a hypothesis, which is that maybe it's not that we're over fat, that we're under muscle. From the seventies to roughly early two thousands, muscle wasn't even thought of. Then we started focusing on body fat percentage. Now as we continue to transition, we're looking at bioimpedance, and now we're beginning to think about overall muscle amount, but it doesn't end there. The real important marker is the intramuscular adipose tissue. It's the quality of the muscle tissue. Doctor Gabrielle Lyon is a board certified physician with advanced training in nutritional sciences, geriatrics, and metabolism from Washington University in Saint Louis. She is redefining health and longevity by placing skeletal muscle, the organ of longevity, at the center of aging, disease prevention, and human performance.

I think building muscle is probably one of the best ways to lose body fat, but also to break your metabolism, lower inflammation, improve your cognitive function. Improve your immunity. Help your sexual function. I mean, pretty much everything. More muscle, better sex. Now we have everyone's attention.
