Intermittent fasting is not a traditional diet, it is more of a specific style of eating characterized by eating during a set duration of time followed by a longer than usual fasting period. The most popular method of following intermittent fasting is called the 16-8 method, where all of the day’s calories are consumed during an eight hour window bookended by 16 hours of fasting. Other types of intermittent fasting include the 5-2 method, in which a person would eat regularly for five days of the week and consume little on two nonconsecutive days. Generally on the fast day calories will be capped at 500; this method can be successful as long as additional calories are not consumed to compensate on the non-fasting days. Another method of intermittent fasting involves normal eating patterns with longer fast periods interspersed, usually between 24 to 36 hours.
