Insulin Sensitivity describes how well your cells respond to insulin. When sensitivity is high, cells take up glucose efficiently with smaller insulin signals. When sensitivity is low (insulin resistance), the pancreas must pump out more insulin to achieve the same effect—and fat-burning is blocked.
Key Effects
- •Glucose gatekeeper — insulin determines which fuel your system burns
- •Software lock — high insulin prevents access to stored fat
- •Fat-burning — low insulin signals allow fat oxidation and ketone production
- •Metabolic flexibility — sensitivity enables seamless fuel switching

To unlock dual-fuel capability, you must master Insulin Sensitivity. Intermittent fasting, post-meal movement, and Zone 2 training all improve this metric. The Metabolic Flexibility article details the protocols.
