How Does Intermittent Fasting Work?
Intermittent fasting changes your body in big ways. It helps you lose fat and get healthier. It does this by changing how your body works and your hormones.

Fasting also changes your hormones. Your insulin levels go down, making it easier to use fat for energy. At the same time, your human growth hormone (HGH) goes up.
More HGH helps you lose fat and grow muscle. These changes make fasting a great way to stay healthy and fit.
