fasting metabolism

Fasting metabolism refers to how your body generates energy when you're not eating, such as between meals or overnight. Initially, it uses stored carbohydrates (glycogen) for fuel. Once those are depleted, it switches to burning fat stores, converting fat into energy. Over time, the body’s metabolic processes adapt to conserve muscle and use fat more efficiently. This shift helps maintain essential functions, like brain and organ activity, while conserving energy reserves. Essentially, fasting metabolism is your body's way of balancing energy needs and storage during periods without food intake.
