Intermittent fasting

Intermittent fasting, also known as intermittent energy restriction, is an umbrella term for various meal timing schedules that cycle between voluntary fasting (or reduced calorie intake) and non-fasting over a given period.Three methods of intermittent fasting are alternate-day fasting, periodic fasting, and daily time-restricted feeding. Intermittent fasting may be similar to a calorie-restriction diet, and has been studied in the 21st century as a practice to possibly reduce the risk of diet-related diseases, such as metabolic syndrome. However, intermittent fasting has been criticised as a fad.The science concerning intermittent fasting is contested. The American Heart Association (AHA) states that intermittent fasting may produce weight loss, reduce insulin resistance, and lower the risk of cardiometabolic diseases, although its long-term sustainability is unknown. The US National Institute on Aging states that there is insufficient evidence to recommend intermittent fasting and encourages speaking to one's healthcare provider about the benefits and risks before making any significant changes to one's eating pattern. A 2019 review concluded that intermittent fasting may help with obesity, insulin resistance, dyslipidemia, hypertension, and inflammation.Fasting exists in various religious practices, including Judaism, Christianity, Hinduism, Islam, Jainism, and Buddhism.
