The Biology of Longevity: Protecting Muscle, Metabolism & Fitness
Healthy aging depends on three non-negotiables: maintaining muscle, preserving metabolic flexibility, and sustaining cardiorespiratory fitness.
Sarcopenia Prevention (Muscle Loss)
After age 30, adults lose 3–8% of muscle mass per decade — accelerating after 60. This silent epidemic doesn’t just weaken strength; it fuels frailty, falls, metabolic decline, and insulin resistance. At Sequoia, we quantify and reverse muscle loss with InBody 770 body composition analysis, personalized resistance training, and protein-forward nutrition. Protecting muscle is protecting independence, metabolism, and longevity.
Metabolic Health
Insulin resistance, visceral fat, and chronic inflammation accelerate biological aging. By combining advanced diagnostics with continuous glucose monitoring (CGM), lipid subfractions, and inflammatory markers, we detect metabolic dysfunction early — and intervene before disease develops.
Cardiorespiratory Fitness
Few markers predict survival as powerfully as VO₂ max. Studies show those in the lowest 5% of cardiorespiratory fitness face up to a 500% higher risk of all-cause mortality compared to the fittest 5%. In other words, fitness is medicine — one of the most potent tools for extending both lifespan and healthspan.
At Sequoia Medical 360, we treat fitness as a measurable, trainable vital sign:
