The science
Metabolism is how our bodies use energy, and insulin is the hormone that directs that process. With age and poor diet, cells become less responsive, keeping insulin levels high. This speeds aging by blocking fat burning, raising blood sugar, and fueling inflammation. Restoring insulin sensitivity rebalances energy and extends healthy years of life.
What is Metabolism?
(MUH-TAB-UH-LI-ZUHM)
Metabolism refers to the chemical reactions and processes of the body that sustain life. It encompasses our ability to convert food into energy, build what we need to thrive, and eliminate what we don’t. In our younger years, metabolic function tends to be optimal, helping us grow, perform, recover, and remain resilient. As we age, metabolism declines and a loss of function follows. Metabolic dysfunction sits at the core of nearly every chronic disease of aging. Protecting metabolism is central to preserving long-term health.
What it means for healthspan
Interventions can help
Support mitochondria
Efficient metabolism enhances how cells produce energy, reducing oxidative damage and promoting long-term cellular health.
Stabilize glucose levels
Maintaining stable glucose and insulin levels reduces metabolic stress, protects against insulin resistance, and supports recovery systems.
Restrict targeted fuels
Tight metabolic controls deprive damaged or senescent cells of the excess nutrients and growth signals they rely on to thrive.

Frequently asked questions
Metabolism involves far more than just burning calories. At the cellular level, it shapes how your body transforms nutrients into energy, regulates inflammation, and coordinates hormone and gene activity. Interventions like Acarbose and SGLT-2 inhibitors work by optimizing these underlying pathways to improve metabolic efficiency and extend healthspan, independent of weight loss alone.
A slow metabolism does not necessarily mean accelerated aging. What matters more is metabolic rigidity, which refers to the body's reduced ability to switch between using glucose and fat for fuel. This inflexibility increases cellular stress and contributes to age-related decline. Therapies that restore metabolic flexibility help reduce this burden and support healthier aging.
Normal blood sugar is only one part of the picture. Optimal metabolic health also requires strong insulin sensitivity, low glucose variability, and healthy mitochondrial function. Even with stable blood sugar, deeper dysfunction can exist. Metabolic interventions target these root causes to enhance energy production and reduce long-term cellular stress.
Metabolic flexibility allows your body to alternate between using carbohydrates and fats for energy based on availability and need. When this flexibility is lost, the body becomes dependent on glucose, leading to energy crashes, cravings, and fatigue. Improving metabolic flexibility stabilizes energy levels and enhances endurance throughout the day.
Mitochondria generate the energy your cells need to function. When they become inefficient, cells produce less energy and more oxidative byproducts, which damage tissues and accelerate aging. Supporting mitochondrial health through metabolic interventions helps maintain energy balance, reduce oxidative stress, and preserve cellular resilience over time.
Disrupted metabolism often leads to chronic low-level inflammation, a key driver of aging and disease. Insulin resistance, mitochondrial dysfunction, and poor nutrient signaling can all trigger inflammatory pathways. Improving metabolic control reduces this inflammation at the source, supporting immune balance and long-term vitality.
