How It Affects Your Body

The body has multiple benefits while fasting and this includes lower blood sugar levels, increased growth hormone, and fat burning. One of the main benefits is weight loss; by fasting, the body naturally starts to break down fat in order to use it as energy. This creates an increase in basal metabolic rate, making fat burning more efficient. Lowering insulin levels decreases fat storage, helping to keep your body leaner and healthier.
