16/8 Method 

This popular weight-loss method is where you spend 16 hours without food but unsweetened beverages like water, coffee, and tea. For the remaining 8-hour window, you can literally eat whatever you want.

5:2 Diet

This diet trend allows you to eat normally for 5 days, then on 2 scheduled fasting days that week, you eat about 25% of your recommended calorie needs. For example, a person who regularly eats about 2,000 calories per day would eat 500 calories on fasting days. People usually space their fasting days out, like planning them for Tuesdays and Fridays.

Alternate-day Fasting

Alternate-day fasting is considered one of the most extreme forms of intermittent fasting, so it’s not recommended for beginners. On this diet, you cycle between feeding and fasting days. On feeding days, you eat whatever you want but the next day you eat almost nothing on fasting days.

The Warrior Diet

Originally created in the early 2000s, sometimes referred as a 20:4 fasting, the warrior diet involves fasting for 20 hours with a 4-hour fuelling window. This principle is based on the idea that ancient warriors would eat very little during the day and feast at night.

Spontaneous Meal Skipping

There are no solid rules for this diet. You simply allow yourself to skip meals from time to time throughout the week whenever you don’t feel hungry, too busy to eat or too lazy to cook.
