Intermittent fasting is an eating pattern that involves alternating periods of fasting and eating. Here are the various phases in Intermittent Fasting, ordered by when they occur after starting the fast:

The Fed State: This is the period of time where the body is digesting and absorbing food, which typically lasts for 3-5 hours after eating. During this time, insulin levels are elevated, glucose is being metabolized, and fat storage is inhibited.

The Post-Absorptive State: This phase starts after the Fed State and lasts for approximately 12-16 hours. During this time, insulin levels start to decline and the body starts to switch from glucose to fat as its primary source of energy.

The Fasting State: This phase begins when the body has fully transitioned to using fat as its primary source of energy, which typically occurs after 12-16 hours of fasting. During this phase, the body ramps up the production of hormones and enzymes that promote fat burning and the breakdown of stored fat.

The Re-Feeding State: This phase occurs when the individual breaks the fast and begins eating again. The insulin levels start to rise, glucose is once again metabolized, and fat storage is inhibited. This cycle repeats itself with each subsequent meal.

It's important to note that the length of each phase can vary based on the individual's starting weight, age, gender, and activity level. Additionally, Intermittent Fasting is not appropriate for everyone, and it's always best to consult with a healthcare professional before starting any new diet or eating pattern.

Here are a few common patterns of Intermittent Fasting:
* 16-8
* OMAD (one meal a day)
* ADF (alternate day fasting)
* 5:2 Fasting (eating for five days, fasting for two)

There are can be many potential benefits of Intermittent Fasting, such as:
* Increase in free time
* Weight loss/management
* Managing various health conditions such as obesity, diabetes, cardiovascular disease and others.
* Improvement in focus
