mTOR Muscle Paradox Letter: staycuriousmetabolism.substack.com/p/the-aging-muscle-paradox-how-to-keep?r=40ekz2
Molecular Choreography of Acute Exercise, Interview with Michael Snyder: youtu.be/_9ywulQF2Ho
Description:
Skeletal muscle isn’t just about strength or aesthetics. In this video, we break down why muscle quality may be one of the most underappreciated determinants of long-term health, and why it’s never too late to start building it.
We unpack a core idea that reframes modern metabolic disease: healthy skeletal muscle can be more important than a “healthy weight,” not the other way around. From muscle’s role in glucose disposal and fat oxidation to its signaling effects on the brain, immune system, and mitochondria, muscle emerges as a central regulator of whole-body health.
We also explore emerging concerns and controversies—GLP-1 drugs and sarcopenia risk, the mTOR “muscle paradox,” protein intake in light of new dietary guidelines, and how exercise-induced myokines drive inter-organ communication with implications for Alzheimer’s disease and aging.
