It’s no surprise that intermittent fasting is one of the most popular types of eating plans. You don’t need to measure out food or buy any prepackaged shakes. There are no required weigh-ins or calorie counting. All you really have to do is not eat during certain hours. It’s pretty simple.
There are different ways to go about it, of course. Most people do the 16:8 diet, in which you fast for 16 hours and then eat within an eight-hour window. There’s also the 5:2 diet, where you drastically cut back on calories just two days a week, and there are 24-hour fasts, where you don’t eat anything one day each month.
Regardless of the method, significantly restricting when you eat can throw your body for a loop and cause a handful of odd side effects. Intermittent fasting may not be suitable for everyone. (People with a history of disordered eating, for example, should definitely avoid it.)
