Understanding Fasting and Metabolism
Fasting refers to voluntary abstinence from food for a certain period, typically ranging from 12 to 24 hours. This pattern can influence metabolism by reducing insulin levels, promoting fat burning, and increasing growth hormone levels.
Metabolism is the body’s process of converting food into energy. During fasting, the body shifts from using glucose to using fat as fuel—a state known as ketosis. This process supports weight loss and improves metabolic flexibility.
