Overview
Intermittent fasting (IF) is a diet that cycles between periods of voluntary fasting or reduced calorie intake and non-fasting over a given period, aiming to improve health outcomes. With various methods, IF has been studied for its potential benefits in overweight or obese adults, including improved insulin sensitivity, weight loss, and reduced inflammation. While preliminary evidence suggests IF is generally safe, its effects on blood pressure are less pronounced than continuous energy restriction, and adverse effects have not been comprehensively studied, leading to caution from health organizations like the United States National Institute on Aging. As a form of fasting, IF is a subclass of fasting diets and has been practiced for centuries, with modern methods and research aiming to understand its full potential and risks, and influencing related concepts like caloric restriction and ketogenic diet.
