Intermittent fasting refers to an eating pattern that cycles between periods of fasting and eating. Intermittent fasting is of different types. The popular methods among them include 16/8 method, 5:2 diet, Eat Stop Eat, Alternate-day fasting, Warrior Diet, Spontaneous meal skipping among others.x 

There are several physiological and psychological advantages of intermittent fasting. It is mainly used as a weight-loss technique. When done in the proper method, this could free up some time to be productive also.

Fasting is super popular among people who are also following a Ketogenic diet as well. A keto high-fat low-carb diet will make fasting easier. Intermittent fasting may help you get into ketosis even faster and perhaps achieve higher ketone levels. 

Researchers suggest a longer intermittent fast followed by shorter daily intermittent fasts. You can use a fasting protocol that includes fasting for up to 3 days, 3 times a year with a shorter 16 to 20 hour fast on the days before and after the 3-day fasts. Include mineral-rich foods and supplements in your food to avoid excess mineral loss caused by keto diet and fasting.
