Intermittent fasting (IF) refers to an eating pattern, rather than a diet, where you cycle between periods of fasting and periods of eating. It is very popular for weight loss, health, and well-being - benefits that are now well-established . IF is much easier when you're in ketosis because ketosis has a natural appetite-suppressing effect . If you’re going through a ketogenic diet weight-loss plateau, intermittent fasting may also help you break out of it.
There are different IF methods, but the most popular one is known as the 16/8 method. It involves fasting for 16 hours a day (this is normally done by skipping breakfast and extending the normal ‘fast’ everyone does during the night) and restricting the eating ‘window’ to 8 hours a day (for example eating the first meal at 11:30 am and the last meal by 7:30 pm).
Although food is now allowed during the fasting period, you can drink water, coffee, tea or other non-caloric beverages. During your eating window, you can eat according to your appetite, and your meals should be substantial enough to ensure you eat only once or twice within a given day.
