Fasting protocols can influence metabolic health by altering insulin sensitivity and promoting fat oxidation, leading to better weight management. Intermittent fasting, for instance, allows the body to enter a state of ketosis, where it relies on fat stores for energy, improving overall metabolic efficiency. Additionally, fasting can enhance autophagy, a process that aids in cellular repair and rejuvenation. However, it is important to approach fasting carefully and consult with healthcare professionals, as results can vary based on individual health status and lifestyle.
