What Is Intermittent Fasting?

You naturally fast while you sleep everyday. Intermittent Fasting takes this "fast" a little bit further. (That's also why your breakfast is called "break-fast"🤯) In order to truly "fast", you need to wait at least 12 hours from your last meal (at dinner) to eat your first meal (your "break-fast"). 12 hours of fasting is when autophagy starts to kick in and your cells begin cleaning themselves out (see the next section for more details).

Ideally, you want to aim for a 16 hour fast with an 8 hour "eating window" to maximize your fat burning results while still getting the nutrients you need from your meals to maintain fat burning.

However, it's important to note that this does NOT mean just skipping a meal OR restricting your calories. I review all of these details in my Complete Intermittent Fasting Program.

How Does Intermittent Fasting Work?

Intermittent Fasting helps to get rid of bad mitochondria (your cells energy powerhouse) and allows your gut to rest. This combination helps your body become better at using stored fat as an energy source. Intermittent Fasting also helps to naturally decrease your fat storing hormone, insulin, which allows the fat burning process called lipolysis to naturally turn back on.(1) Not to mention, Intermittent Fasting also aids in significantly reducing bloating by turning on the Migrating Motor Complex (aka MMC).(2) The MMC sweeps out left behind food and bacteria that would normally lead to bloating. By not eating during your fasting period with Intermittent Fasting, your insulin levels naturally dip back down (turning on fat burning) and your MMC starts to kick in (to decrease bloating).
