Express fast is a method of fasting that emphasizes quick and efficient results. It typically involves short periods of fasting, often ranging from 12 to 24 hours, allowing the body to enter a state of ketosis more rapidly. This approach can help with weight loss, improve metabolic health, and enhance mental clarity. During an express fast, individuals may consume water, herbal teas, or black coffee, avoiding solid foods. This type of fasting is popular among those looking for a manageable way to incorporate fasting into their lifestyle without long-term commitment. It can be adapted to fit personal schedules and preferences.
