Intermittent fasting is a method of eating used for centuries to help maintain a healthy weight. It can be used in conjunction with the keto diet or as a stand-alone strategy.

It works by limiting the amount of food you eat during a set period while allowing you to eat without restriction during other times. Some methods of intermittent fasting are also known as the 5:2 diet. The word "fast" simply means don't eat for an extended period, but it's not necessarily related to how long you're sleeping.

Some people consider intermittent fasting a form of time-restricted feeding. It usually begins with a fast during which you eat little to no food for 8 to 16 hours. For example, if you finish dinner at nine in the evening, you would not eat again until nine the following morning - or 12 hours later. 

If this sounds difficult, try to remember that the longest periods of fasting from all foods occur during sleep and include more than 16 consecutive hours without consuming any calories. Intermittent fasting is an effective weight loss tool and can help you lose fat and improve your overall health in many ways.
