Metabolic Health and Fuel Partitioning

Metabolic health can be understood through the concept of fuel partitioning: how the body uses and stores energy.
A metabolically healthy person efficiently accesses and utilizes fat stores for energy, even during low-intensity activities like walking.
In contrast, a metabolically unhealthy person relies more on glucose and glycogen, even for light exercise, indicating less efficient energy usage.
This difference in fuel utilization is a key distinction between metabolically healthy and unhealthy individuals.
Mitochondrial efficiency plays a significant role, as mitochondrial dysfunction is a hallmark of aging.
