It is claimed to cause weight loss, improve metabolic health and perhaps even extend lifespan.

Not surprisingly given the popularity, several different types/methods of intermittent fasting have been devised.


Here are 6 popular ways to do intermittent fasting.


The 16/8 Method involves fasting every day for 14-16 hours, and restricting your daily “eating window” to 8-10 hours.





It is generally recommended that women only fast 14-15 hours, because they seem to do better with slightly shorter fasts.

For people who get hungry in the morning and like to eat breakfast, then this can be hard to get used to at first. However, many breakfast skippers actually instinctively eat this way.

You can drink watercoffee and other non-caloric beverages during the fast, and this can help reduce hunger levels.


I personally find this to be the most “natural” way to do intermittent fasting. I eat this way myself and find it to be 100% effortless.

I eat a low-carb diet, so my appetite is blunted somewhat. I simply do not feel hungry until around 1 pm in the afternoon. Then I eat my last meal around 6-9 pm, so I end up fasting for 16-19 hours.




The 5:2 diet involves eating normally 5 days of the week, while restricting calories to 500-600 on two days of the week.

This diet is also called the Fast diet, and was popularized by British journalist and doctor Michael Mosley.



As critics correctly point out, there are no studies testing the 5:2 diet itself, but there are plenty of studies on the benefits of intermittent fasting.




This method was popularized by fitness expert Brad Pilon, and has been quite popular for a few years.


For example, if you finish dinner on Monday at 7 pm, and don’t eat until dinner the next day at 7 pm, then you’ve just done a full 24-hour fast.


Water, coffee and other non-caloric beverages are allowed during the fast, but no solid food.

If you are doing this to lose weight, then it is very important that you eat normally during the eating periods. As in, eat the same amount of food as if you hadn’t been fasting at all.


However, you don’t need to go all-in right away, starting with 14-16 hours and then moving upwards from there is fine.

I’ve personally done this a few times. I found the first part of the fast very easy, but in the last few hours I did become ravenously hungry.

I needed to apply some serious self-discipline to finish the full 24-hours and often found myself giving up and eating dinner a bit earlier.

BOTTOM LINE:Eat-Stop-Eat is an intermittent fasting program with one or two 24-hour fasts per week.

4. Alternate-Day Fasting: Fast every other day.

Alternate-Day fasting means fasting every other day.






5. The Warrior Diet: Fast during the day, eat a huge meal at night.

The Warrior Diet was popularized by fitness expert Ori Hofmekler.

It involves eating small amounts of raw fruits and vegetables during the day, then eating one huge meal at night.

Basically, you “fast” all day and “feast” at night within a 4 hour eating window.

The Warrior Diet was one of the first popular “diets” to include a form of intermittent fasting.

This diet also emphasizes food choices that are quite similar to a paleo diet – whole, unprocessed foods that resemble what they looked like in nature.


6. Spontaneous Meal Skipping: Skip meals when convenient.

You don’t actually need to follow a structured intermittent fasting plan to reap some of the benefits.

Another option is to simply skip meals from time to time, when you don’t feel hungry or are too busy to cook and eat.

It is a myth that people need to eat every few hours or they will hit “starvation mode” or lose muscle.

The human body is well equipped to handle long periods of famine, let alone missing one or two meals from time to time.

So if you’re really not hungry one day, skip breakfast and just eat a healthy lunch and dinner. Or if you’re travelling somewhere and can’t find anything you want to eat, do a short fast.

Skipping 1 or 2 meals when you feel so inclined is basically a spontaneous intermittent fast.

Just make sure to eat healthy foods at the other meals.

BOTTOM LINE:Another more “natural” way to do intermittent fasting is to simply skip 1 or 2 meals when you don’t feel hungry or don’t have time to eat.

Take Home Message

There are a lot of people getting great results with some of these methods.

That being said, if you’re already happy with your health and don’t see much room for improvement, then feel free to safely ignore all of this.

Intermittent fasting is not for everyone. It is not something that anyone needs to do, it is just another tool in the toolbox that can be useful for some people.

Some also believe that it may not be as beneficial for women as men, and it may also be a poor choice for people who are prone to eating disorders.

If you decide to try this out, then keep in mind that you need to eat healthy as well.

It is not possible to binge on junk foods during the eating periods and expect to lose weight and improve health.

Calories still count, and food quality is still absolutely crucial.
