What is intermittent fasting?

Intermittent fasting is more about the “when” than the “what.”

The first findings of the benefits of intermittent fasting date back to decades of studies on rodents. This research suggests that eating smaller amounts of food over a shorter period of time can reduce the risk of age-related diseases while extending overall lifespan. These benefits are attributed to a concept called metabolic switching.

Typically, this shift occurs after about 10 hours of fasting, when the body's glycogen level drops and it begins to consume ketones, the fuel the liver makes from fat. The body then enters what is called “ketosis,” a phenomenon you may have heard about in connection with the ketogenic diet.

The number 16 indicates the number of hours you have spent without eating, and the number 8 indicates the window of hours during which you can eat.

The second option, 20/4, is called the Warrior Diet. This corresponds to skipping two meals, either breakfast and lunch or lunch and dinner. This type of fasting is also called the OMAD “one meal a day” diet which translates to “one meal a day.”
