Yes, you can burn fat after 18 hours of fasting. During a fast, the body exhausts glucose stores and begins to use fat for energy, leading to fat burning. This process, called ketosis, usually kicks in after 12-16 hours of fasting. However, individual results may vary, and it's important to consult with a healthcare provider before starting any fasting regimen.
