Fasting, an ancient practice now gaining popularity, involves using your body's energy reserves for various benefits. These include weight loss, cancer prevention, improved brain function, enhanced cellular energy, autophagy for cellular cleanup, and better cardiovascular health. Different fasting methods like alternate day fasting, 5:2, or 18:6 offer flexibility. However, fasting isn't suitable for everyone, especially those with certain medical conditions, so professional guidance is crucial to reap its benefits safely. Properly executed, fasting can offer numerous advantages, but it requires careful consideration and guidance to avoid potential risks.
