Then here we go…

Note: As you already know, running is hard.

Add to that daunting nature of fasting then you got yourself a dangerous recipe—one that might spell disaster on your health if you are not careful enough.

So, please consult with your physician before you attempt any extreme change to your current diet/training plan.

You have been warned.

It’s better to be safe than sorry.

Intermittent Fasting – The Definition

Intermittent fasting consists of a pattern of fasting and eating over a defined period. 

It’s an eating method that cycles between fasting—calorie restriction—and normal eating during a specific period.

IF limits how much food eats for a given period, followed by an interval of normal eating known as the feeding window.

You’ll be fasting –not eating—for a period ranging from 16, 20, to even 36 hours, depending on the IF method you choose.

Intermittent fasting is not new.

It has been practiced for millennia and has been used by many religions—mainly Judaism and Islam— for healing and spiritual enlightenment.

These belief doctrines regard that fasting as a powerful healing method that allows the human body to take time out from the food toxins that are present in our bodies, and as means for reaching higher spiritual existence.

The controversy—is it worth the trouble?

The practice is still controversial since it flies in the face of many established beliefs, such as the importance of breakfast and frequent meals to keep metabolism soaring and prevent muscle breakdown.

However, a series of research papers has revealed that intermittent fasting provides many benefits.

What’s more?

Looking to lose weight? Fasting may boost your body’s fat-burning potential.

Restricting your food intake during certain times of the day is a powerful hack for losing the pounds quickly and keeping them off, research shows.

When you fast, your body runs out of its main fuel source—glucose, thus forcing the body to switch to using up fat as the main source of energy.

Fasting can boost the growth hormone, which has vital muscle-building properties, increases during fasts.

The human body has evolved to thrive during shorts intervals of going without food.

It’s also great for people on the ketogenic diet.

Intermittent fasting may assist your body to attain ketosis faster than the keto diet alone.

Intermittent fasting can also help you live longer.

According to a study out of the University of Southern California’s Longevity Institute, fasting decreases the release of IGF-1, which is an insulin-like growth factor that drives the aging process and activates other DNA repair genes.

The Downside

The benefits of intermittent fasting can vary from one person to the next.

And it’s not for everyone.

There is a catch to it.

To get the most out of this diet, you need to be aware of its downsides as well.

Hunger is the biggest issue.

Going for long periods without food is something we in the developed world are not used to.

Don’t Eat Crap

Just because you are fasting doesn’t mean that you can eat whatever you want during the feeding window.

That’s a common mistake.

People who fast are much more likely to binge and reach for high-calorie foods when they eat again.

This could be counterproductive.

Here’s the perplexing part.

There are many various ways to start intermittent fasting.

The method may differ in the number of fast times and calorie allowances.

Different people have different needs; therefore, different styles will suit them and help them get the most out of practice.

There are many ways to start intermittent fasting.

Just like any other health program, how you get started hinges on your fitness goals, workout routine, physiology, genes, and lifestyle—to name a few.

Break The Fast Right

Once it’s time to break the fast, make sure to go for a meal that includes plenty of complex carbs and proteins.

In other words, stick to healthy food choices.

Or it’s a no deal.

Supplement Just In Case

During intense training days—if you have any speedwork or long run scheduled—take a supplement, such as BCAA.

Here a few recommended dosages:

5 g of BCAAs before your run

5 to 10 g of BCAAs during long running sessions, and

10 to 15 of BCAAs immediately following a hard run.

Start the Fast

There are many ways to approach intermittent fasting.

The method you are going to choose depends, mostly, on your fitness goals, workout schedule, physiology, personal preference, lifestyle conditions and other factors.

Therefore, if you’re serious about giving IF a try and go, here are some plans to help you proceed.

1. The Periodic Fast

If you’ve never tried fasting before, then the periodic fast should be your trial fast—Your opportunity to take IF for a test drive first before you commit to anything serious or long term.

Also, if it’s your first time doing it, be sure also to write down your thoughts and note then use it as a reference for future practice.

The How

This method entails a fast for 24 hours, starting at any time of the day, preferably on a Sunday.

You can start at a specific time, on Saturday at 11 pm, for instance, drink plenty of water, then break your fast on Sunday night.

For the most part, you should not do this method more than one or two times a week.

2. The Warrior Diet

The Warrior Diet method consists of 20 hours of fasting, then a four-hour feeding period, consuming one healthy meal a day.

This method can help you boost energy levels, shed weight, increase muscle mass and save you money.

The How

During the feeding window, usually dinner time, go for one large meal, aiming for roughly 2000 calories (or more, depending on your needs) in one sitting.

For the best results, put the feeding window at the end of the day, as it’s more suitable for family dinners and post-run sessions.

If you have a run or workout on schedule,  then plan it at the end of the fast.

3. Leangains

The Leangains method was made famous by author Martin Berkham, and it consists of a 16-hour fast (from 10 p.m. to 2 p.m. the next day for instance), followed by an 8-hour eating window.

This method is great if you’re looking to increase muscle gains while shedding fat.

To make the most out of Leangains, skip breakfast on a daily basis, then break your fast roughly eight hours after waking up.

During the leangains approach, make sure the bulk of your calories during the post- run window, following a diet that’s high in protein, complex carbohydrates, and some of the healthy fats, like olive oil and avocados.

The How

For example, on this plan, you’d fast from 9 pm on Monday night until 1 pm Tuesday afternoon.

If you were planning to run, you’d do it on Tuesday afternoon.

4. Alternate-Day Fasting

This is a similar approach to the last method but involves eating within a 24-hour window followed by 24 hours of true fasting every two-day cycle.

In other words, with this method, you simply eat every other day.

The Alternate-Day Fasting approach promotes weight loss and decreases the risks of coronary artery diseases, according to research by the University of Illinois at Chicago.

During the feeding period, you’re allowed to eat what you want, aim for a broad range of healthy food choices—especially if the 24-hour fast is a bit too much.

The How

This is really simple.

All you have to do here is to fast on one day, and then eat healthy the next day.

Listen to your body

In the end, you are the boss, and you get to decide which approach works the best for you.

With that said, to do that, you need to keep in mind that it’s of paramount importance to listen to your body’s signal of pain and discomfort—mainly your hunger signals.
