Intermittent fasting is a pattern of eating. It involves cycling between periods of fasting and periods of eating. An example of an intermittent fasting day would be to skip breakfast then have a meal at around 1 pm. Then your next meal will be at around 8 pm and then the cycle will repeat. This means you leave a considerable amount of time between your meals which puts your body into a fat burning state. This is because you have been able to burn all the calories from your previous meal and are now using your body fat for energy. This is the main reason the diet is so popular for weight loss.

One of the most popular types of fasting is 16/8 fasting. This involves having a window of 8 hours in the day when you are allowed to eat and consume calories. After these 8 hours you will then enter a 16-hour fating period where you will not be able to consume any food or calories. This is probably the easiest way of fasting as you can still eat your normal meals during that 8-hour period and the 16 hours can be your rest time and sleep time where you wont be as in much demand for calories and food.
