Intermittent fasting is a pattern of eating that alternates between periods of consuming food and abstaining from it. This dietary strategy, which includes protocols like the 16/8 method, the 5:2 diet, and eat-stop-eat, aims to improve health and promote weight loss by leveraging the body’s metabolic responses to fasting. Research supports its potential in improving body composition, enhancing cognitive performance, and reducing risk factors for diseases like diabetes, heart disease, and neurodegenerative disorders.
