Flexible intermittent fasting is basically what it sounds like, it is a form of fasting that does not follow a specific regimen or script. It allows a person to have a bit more flexibility in following a fasting routine, thus making it feel a bit less restrictive. As with this version of fasting that we use in the Fire Team Whiskey® .50 Cal Eating Plan, we would only recommend this version of fasting if a person has demonstrated an ability to quickly switch from "on plan" to "off plan" without any struggle. Meaning, if you are the type of person who has a cheat meal, that turns into a cheat day, that turns into a cheat week, this version of intermittent fasting is not for you. This version of intermittent fasting is for someone who has demonstrated a high level of self-discipline on their current eating plan, and any "off track" changes don't result in major setbacks.
With flexible intermittent fasting, you have a daily goal to meet a fasting window, commonly its 16 hours. A flexible faster may consume some fat during that fasting window, for example, drinking coffee with heavy cream and MCT oil or butter, but still consider themselves on a fast. This allows for a person to potentially last longer before they break their fast by providing some hunger satiation with the use of consuming a small amount of fat.
Another version of flexible fasting is that a person may also have a daily goal of fasting for 16 hours, but based on life circumstances, may "flip" their time window for their fast depending on their schedule that day. For example, I usually fast from 8:00 PM until about 2-4PM the next day. But on Sundays, I like to go eat brunch with friends, so I will "flip" my fast window, and make that my only meal for the day, thus doing a Noon to 8 am the next day fast.
Flexible fasting is a great way to get many of the benefits of a fast, but without some of the stress and suffering of traditional fasting.
