    자주 묻는 질문

    The metabolic switch is a measurable biochemical transition that occurs when the body runs out of glycogen, which is stored sugar in the liver. Instead of relying on glucose from recently consumed carbohydrates, the body pivots to mobilizing stored body fat, known as triglycerides. This shift allows the body to function as a hybrid system, utilizing stored energy reserves rather than requiring constant food intake to maintain performance.

    Ketone bodies are produced when the body begins converting fat into energy after glycogen stores are depleted. A primary ketone body is beta-hydroxybutyrate, or BHB, which acts as a high-performance fuel source. Beyond being a backup power supply, BHB serves as a signaling molecule that instructs cells to begin repairing DNA and boosting antioxidant production, functioning much like a premium rocket fuel for the body's systems.

    The body operates on two main fuel sources: glucose and triglycerides. Glucose comes from carbohydrates and provides immediate energy, while triglycerides represent stored body fat that acts like a battery's charge. Most people constantly 'top off' with glucose, but the metabolic switch allows the body to stop plugging into external food sources and instead utilize the triglycerides already stored in the body for sustained energy and cellular repair.
