Wild Guide To Fasting

A Short Guide To Intermittent Fasting

 

An intro to fasting

I've been using IF—short for intermittent fasting—for years.

It is my belief that IF coupled with eating the highest quality foods available is the answer to lifelong health and wellness. 

I feel great just about every day. I eat when I want and if I want. I almost never feel "hungry" or "tired."

And when I decide to have a cheat meal, it's easy to get right back to my regular life soon after.

In this guide, I'm going to share with you my personal experience with fasting. And by the end, I hope you will take it upon yourself to implement some kind of fasting schedule in your life.

But before we dive into why you should incorporate some kind of IF schedule into your life, we need to set a few things straight.

Fasting Misconceptions

As it goes with most things that's in the public consciousness, there are many misconceptions around intermittent fasting.

First of all, practicing intermittent fasting does not (necessarily) mean eating less calories.

Calorie restriction is eating less calories while intermittent fasting is when you eat your calories each day and is independent from how many calories you eat in aggregate.

It makes sense that most people confusing the two, but for our purposes, we need to clearly delineate the difference so there is no confusion or scapegoats that will result in the points being overlooked.

Going extended periods of time without food, usually for 24 hours or longer, is known as traditional fasting.

And while you should fast this way sometimes because of the health benefits, intermittent fasting is something different entirely and what we will be focusing on today.

Intermittent basically means intervals.

To intermittent fast means to space your meals out at various times, or simply put, to eat in intervals.

The intervals will vary depending on what IF style you use.

As an example, let's say you typically eat 2000 calories a day over 4-6 meals.

Then Monday rolls around and you decide to try IF, so instead of eating your 2000 daily calories over 4-6 meals, you opt to eat the same amount of calories over 1, 2 or 3 meals with gaps between each meal and/or within a defined "feeding window." (More on feeding windows below.)

Your calories stay the same, but when you eat those calories changes. 

This is, in a nutshell, intermittent fasting.

Of course, most people hear intermittent fasting and assume it's about not eating.

But that's not accurate. Intermittent fasting is meal timing.

This is why everyone should practice some form of IF; Since we all have to eat food, we might as well choose a eating style that that promotes our health and wellbeing over one that detracts from it.

(Hint: Eating often is not promoting health and wellbeing, and is more likely than not promoting insulin resistance and fat gain.)

This brings us to one of the greatest food lies ever sold by the big food and supplement companies: eating to "stoke your metabolism."

This counterintuitive advice is counterintuitive for a reason: because it counters what really works!

Nutrition tip for cows: don't fast! (Humans: Fast!)

Nutrition tip for cows: don't fast! (Humans: Fast!)

Contrary to what the powers at be would have you believe, the human body is not designed to graze all day long the way a cow does.

There is evidence that can be found in our actual biology that shows why this is (stomach size and microbial makeup), but a simpler way to explain it is to simply think about what cows actually eat—grass.

A cow has to eat enough grass each day to fuel it's massive body, which is why, as a grazing animal, it eats most of the day. After all, grass is a low calorie food and so herbivores have to eat a lot of it to stay alive.

Compare this to another animal in the animal kingdom—the tiger.

A tiger can eat up to 88 pounds of meat in a single sitting. It is estimated that large wild predator cats eat around one 88 pound animal a week.

What this mean is, a tiger finds prey, on average, once every week, at which point he will then feast to his heart's content.

Then he fasts until his next large meal.

A true carnivore.

And while humans aren't true carnivores—we are actually omnivores because we can eat hundreds of different forms of food—we have very strong carnivore tendencies as is shown in the world our ancestors lived in for hundreds of thousands of years (the wild).

Our human ancestors would regularly go long periods of time between finding calorie-rich meat.

Sure, we would snack on berries, twigs, leaves and anything else we could find as we spend our days walking through the vast wilderness (it is estimated that our ancestors walked about 13 miles a day on average).

But no tribe of 20-50 humans is going to survive on berries and leaves because the calories simply aren't there.

  • A cup of blueberries contains about 80 calories.
  • A cup of raw spinach contains about 7 calories.

(Yes, that's a measly 7 calories in a cup of spinach. Keep in mind, you would chew until your face in sore to get through a cup of raw leafy spinach.)

Now let's look at the calorie content of more calorie and nutrient dense foods typically found in the natural human diet.

  • Avg calories in a pound of red meat: 1506
  • Avg calories in a pound of salmon: 944
  • Avg calories in a pound of nuts: 2508
  • Avg calories in a pound of coconut: 1605

If you really wanted to get scientific with it, you could figure out the near-exact calories needed for a small tribe of 40 mixed-sex homo sapiens and then convert that into the amount of spinach and berries you would need to forage (in the wild, remember) to sustain life. 

Then compare that to a diet with meat, fish, nuts and seeds added in here and there. 

But you don't need to do that because I did it for you.

To sustain 40 humans in the wild for a single day, you would need 12,814 pounds of spinach.

Blueberries do a bit better: 5,192 pounds of raw blueberries would be needed to keep alive 40 homo sapiens for one day.

(Disclaimer: the calories needed per day in these calculations is based on Harvard Medical School recommendations, which is probably overestimated. But still. You see the point, right?)

Ha... not even close

Ha... not even close

The way our ancestors survived clearly shows that humans are designed to eat calorie-rich foods... and infrequently.

We do not graze. Therefore, we should not be snacking and eating 6 meals a day.

Anything or anyone that tells you to eat more is full of something (too much food probably, which also means plenty of feces as well).

Be weary of any advice that recommends eating more often.

Your human body is designed to go extended periods of time without food because that is how your (and my) ancestors have survived in the wild for hundreds of thousands of years.

This is, fundamentally, why the research on IF is nearly universal in showing the benefit.

Below we will see how the ways we are built—our biology—makes fasting so darn good for us and, once implemented, naturally easy to maintain.

My Fasting Journey

I've been following an IF style of eating for over 5 years now.

I used to do the 4-6 meals a day thing because that's what the Men's Health magazine said I should do.

I've also done 3 meals a day.

Finally, I've done the "eat whenever I want with no rhyme or reason" style of eating too (in a past life).

Now, with IF, I feel like I've found the light.

I bet you'll feel the same as me once you implement IF in your life.

My typical day goes something like this: I wake up to a mug of Butter coffee or tea, and/or a glass of water with a dash of Wild Pink Salt.

I don't eat "breakfast" in the traditional sense of the word.

My first meal is usually 6-8 hours after waking, sometimes later. This is when I eat breakfast.

My general overall health is the best it's ever been. (My blood work done for life insurance yielded a "perfect" rating.)

I rarely feel the need to eat. I rarely get hungry.

In fact, I often have trouble making myself eat earlier in the day since I'm now so adapted to a fasting schedule. It's hard to be hungry when friends want to eat earlier than my schedule is used to. (So I usually just eat less.)

I now feel oodles better than I used to when I forced myself to eat breakfast each morning. In fact, when I used to eat breakfast in the morning each day because that is what we are all "told" to do, I would regularly "crash" soon after eating, feeling tried and groggy even though I had woken up only a few hours prior. No bueno.

Hint: That's not how a healthy, functioning human body is supposed to feel a few hours after waking.

This is my only breakfast nowadays: Wild Butter Coffee

This is my only breakfast nowadays: Wild Butter Coffee

During my breakfast eating phase, I never really felt hungry in the mornings, but because I've been so conditioned by culture to eat in the mornings, it's what I did. 

And it's probably what you do, too.

Speaking of breakfast, did you know that breakfast means to “break the fast” and has nothing to do with the time you actually break that fast?

In our society, breakfast is something you do in the mornings. But that's not accurate.

(I suspect the cereal companies are to blame for this.)

The fact is, breakfast is your first meal of the day regardless of when you eat it.

My typical breakfast nowadays is 6-8 hours after I wake up. My next meal—and last meal—is usually 4-8 hours after that.

Then I’m done eating for the day.

And that's my intermittent fasting program. Simple. Concise. Works like a boss.

This schedule gives me an average feeding window of 8 hours a day followed by a fast through the night (while I sleep) and into the morning of the next day.

This 16/8 approach to fasting is known as the Leangains approach, credited to Martin B at leangains.com

(16 hours is the fasting period while the 8 hours is the feeding window.)

18/6 fasting schedule

By keeping my daily calories within this 8-hour window, I end up with a 16-hour fast every day.

To follow this fasting protocol, simply focus on keeping your daily calories within the 8 hour "window" after you break your fast. If you stop eating within 8 hours from breaking the fast, you’ll end up with a 16-hour fast each day.

It's surprisingly easy to follow once you get used to it.

And while I recommend you aim for 2 or 3 meals a day during your feed window, some proponents of the 16/8 method suggest you can eat as many meals as you want during that window as long as you stop after the 8-hour window has closed.

I am a bit suspect of this advice, and it doesn't come naturally to me, but it may work for some people.

My preferred way to get the 16-hour fast in each day is to skip breakfast, break the fast 6-10 hours after waking, and then finish my last meal within 8 hours of breaking the fast.

Of course, you should experiment and find what works best for you.

Ultimately, to get the benefits of fasting, your goal is to go as long as you can without food. The more often, and the longer, you go without calories, the more benefit you will get.

So some days you might end up with a 20 or 24 hour fast if you don’t eat until late in the day. While other days, you might start your feeding window a couple hours after waking due to an early meeting or other life event.

As a general rule, the benefits from fasting come when your body has gone 12-18 hours without ingesting any calories. This is why the 16-hour fast every day is so powerful.

Track your Feeding Window to start

When I first started fasting, I tracked my hours closely to make sure I hit the 16 hour fast each day.

Then I didn't think about it and my body did the rest.

Nowadays, my appetite tells me when to eat and not eat.

If you are just starting out, I suggest you track your feeding and fasting hours. This just getting started because it helps you build the habit. (Here's a new app from Kevin Rose for that: Zero.)

Once you get the habit down, not only will you be amazed by how your appetite changes, but your new eating schedule will feel more and more natural as your hormones start to balance out.

When this happens, you'll fall into a natural rhythm, and all you'll have to do at this point is listen to your body.

Nowadays, this is what I do—I listen to my appetite and break my fast whenever it works for my day.

It makes food so simple, so easy, and more enjoyable. 

But make no mistake about what it took to get here; It takes time and patience.

Each person is different, so how hard it is for you is going to be different from how hard or easy it was for me or anyone else.

Just stick with it and you'll reap the many rewards.

Benefits of Intermittent Fasting

Now let’s look at a few of the benefits of intermittent fasting. 

1. Fasting makes your food simple

When you are on a fasting schedule, you will start eating when your body tells you to eat, which will usually average out to 2 or 3 meals a day.

(Women do better on 3 meals a day in the research and empirical data I’ve seen. That said, I know females that do well on two meals a day, sometimes one. Experiment!)

Less meals makes your food life simpler, and as a result, you’ll spend less time eating, preparing and buying food.

2. Fasting is Appetite Control

Another primary benefit of fasting, and one that contributes to helping you lose body fat while fasting, is appetite regulation.

When you fast, you balance out your hormones. This, in turn, reduces the amount of food your body craves, and thus, eats.

You are, simply put, less hungry.

This is all you have to do to get the benefits of appetite control while fasting: When you sit down for a meal, eat at a slowish pace and your body will tell you when to stop eating.

Then stop eating.

Magic.

The human body is an amazing machine, so listen to it and it’ll show you the way.

3. Intermittent fasting is hormone regulation.

Regardless of what you’ve been told, eating more meals does not “spike your metabolism,” or help you lose weight or burn fat.

Just the opposite, in fact, thanks to a hormone you’ve probably heard of called insulin.

Insulin’s primary job in the human body is maintaining glucose levels. It also manages the process of storing glucose in your liver, glycogen (muscle), and fat cells.

Each time you ingest food, your body releases insulin to help manage the glucose (food converts into glucose in your blood) released in your bloodstream.

Insulin helps your body burn off glucose for energy as well as shuttle glucose into your liver, muscles, and if there is extra, into fat cells.

Since most people eat far more than they “burn off” each day, they are unknowingly triggering a state known as hyperglycemia in which they have extra glucose in their blood. This state results in insulin shuttling extra glucose into fat cells.

In a simplified nutshell, this is how you gain fat—more insulin and glucose in your body equals more fat gain.

Each and every time you eat food (aside from outlier exceptions such as consuming ketones or MCT oil), your body releases insulin and glucose. Not only does this release of hormones make it difficult to burn off unwanted body fat, but there are more than a couple health-related problems that come with constant and chronically elevated glucose and insulin levels.

Every time you release insulin and glucose into your body, you are making it more difficult to get your body into “fat burning mode” because you are telling it that you have excess food available, which then triggers your biology to store these excess calories in the form fat for later use.

(Hint: that's how our ancestors survived. There bodies were great at storing fat when they had access to extra calories.)

Furthermore, from the meta-perspective of how your body and brain work together, if you are telling your body that you have food always available, as is the case when you eat frequently throughout the day, your body and mind are trained to keep the cycle going, which manifests in the form of being hungry and tired all the time due to your hormones running amuck. 

Remember: your and my ancestors lived in a world without modern food preservation, so when they were able to kill a mammoth or other large land animal, they’d eat as much as they could so that their body could would store those extra calories in fat cells for later.

Extra calories stored in fat are a hunter gatherers' best friend.

Fat was a literal insurance policy for our ancestors since it gave them more time to find their next meal. Considering food was varied and never a guarantee, as a hunter gatherer you’d want as much fat on your body as possible.

Of course, nowadays, fat is something we don't want at all. 

But that’s because we (the lucky of us reading this, that is) live in a world where food is guaranteed. We will never starve in our modern world.

In a world where food is always plentiful, there is no need for fat on our body since there is always calories available around us.

Do you see the environmental mismatch here?

The fundamental problem of health for humans relates to this mismatch because our biology has not yet adapted to the advent of agriculture and an always-available food supply.

This mismatch of our food supply and our biology is also why we a soaring obesity rate.

As we now know, our bodies are designed to store calories because it is trying to survive for later. So every time you eat food, your body is going to do its best to store those calories in the form of fat cells because that is what it is designed to do.

A side note : For some people, it’s near impossible to get into fat burning mode without some drastic changes in the form of prolonged calorie restriction and fasting. This is why the more weight you gain, the harder it is to get off and the easier it is to gain even more weight.

No matter how you spin it, the more glucose and insulin you release into your body, the harder it is to control appetite, maintain ideal caloric intake and burn off unwanted fat stores.

Don’t be fooled by the outdated and misinformed advice about eating more often to “stoke metabolism.”

Please, please, please ignore the eat six meals a day nonsense.

This is pure and utter nonsense meant to sell you products you don't need.

Repeat after me: The more often I eat, the more fat I gain.

Repeat that over and over until you get it down.

These are the reasons why, as a general rule for health and longevity, you should always try to eat less food less often.

Which leads me to the next benefit of IF: calorie restriction.

Fasting and Calorie Restriction

There are countless studies showing the longevity benefits of calorie restriction.

Humans are designed to eat less calories and less often than we do today.

Our ubiquitous access to food coupled with the ever-declining quality of our food supply is why we have a ever-growing obesity epidemic.

The typical Western diet is full of low-quality, empty-calorie foods. Take our already-poor diets and add the poor lifestyle habits of snacking, lack of movement, sitting too much, not getting enough sun, staying indoors, etc., and you end up with a severe mismatch of environment that is causing the destruction of the human species.

Compare this to our pre-agricultural ancestors that faced an inconsistent food supply due to a lack of refrigeration, farming and modern food preserving methods, yet lived with great health, virtually no modern disease and a lot longer—on average—than people think.

(Our ancestors low lifespan numbers cited in the media are averages heavily skewed by events such as trauma, for which there was no medicine or 911 to help, and infant mortality, which was very high and brought the numbers down a lot.)

This inconsistent food availability our ancestors faced forced them to sometimes go long periods of time without food or with very little food.

This is one of the reasons that calorie restriction, just like fasting, is a "healthy stress" to the human body.

Whether you want to lose weight or not, calorie restriction has a multitude of health benefits. 

Fasting Styles

There are a few methods to practice intermittent fasting.

As we saw above, my preferred method is the 16/8 “leangains” approach.

There are other methods, though, such as fasting for 24-hours a time once a week.

Other methods of fasting include multi-day fasts every few months. This is something I plan on doing in the near future. Either way, do your research and consult a doctor before trying anything like that.

From empirical evidence I’ve seen in myself and others, the daily 16/8 fasting model seems to be the most popular and easiest to get started with.

All this being said, there is no right or wrong way to fast.

The first thing you want to do is reframe your mental model of food and meal frequency.

  • Stop snacking.
  • Start equating not eating with benefit, with fat loss.
  • Start prolonging how long you go between meals.

These few changes themselves can have life-changing effects.

It can be hard to get out of the “I have to eat” mindset, but until you feel the other side for yourself, you'll never know what you might be missing out on.

(Trust me: you're missing out.)

A final note on eating and muscles.

You don’t have to eat all the time, and you shouldn't.

No, your muscles and gains won’t waste away.

In fact, there are numerous studies that correlate fasting with growth hormone release. (Study.)

There is also research that shows fasting has a protein sparing effect, so if you are worried about “wasting away” in terms of losing your gains, this is unfounded. (Study.)

The improvements in insulin sensitivity you get from fasting, which is one of the biggest overall benefits of fasting, improves production of muscle-building hormones such as growth hormone as well as increases your body’s overall management of hormones—insulin and cortisol being the key players.

Final Notes on The Awesomeness that is Intermittent Fasting

If there is one thing I hope you take away from this piece it is this: Reframe how you think about food.

Food should be someting you eat only when you are hungry—and also something you should not eat sometimes even when you are hungry.

Get out of an eating mindset and get into a not eating mindset.

Remind yourself f this: every time you skip food that you typically would have eaten, you have performed a healthy “stress” for your body. And you are now more likely to live longer and one step closer to controlling your appetite rather than it controlling you.

Eat less food less often and watch as your health and results improve like nothing else you’ve ever done in your life thus far.

It really is that amazing.

Now let’s look at one last “fasting technique” that is near and dear to our heart here at Wild Foods.

Butter Coffee Fasting

Butter coffee is perfect if you are just getting started with fasting because instead of quitting breakfast cold turkey, you get clean calories each morning from grass-fed butter and MCT oil in a delicious frothy butter brew.

These fat calories will help you as you transition from a typical whole food breakfast to a fat-dominated liquid breakfast.

And this can be the stepping stone that will help you eventually wake up to nothing more than a glass of water.

Even though I can now wake up to just a glass of water each morning, I choose to start my day with the Wild Butter Brew because it's delicious and because I like the pure fat calories to help me perform at the top of my game.

I use the same 8/16 fasting model but I don't count my morning mug as breaking the fast.

So I wake up and have a mug of Wild Butter coffee. Then I work for 8-10 hours. Finally, I eat my first meal of the day.

By ingesting only fat from pastured butter and MCT oil, I don’t officially break the fast the way I would if I was eating carbs and protein.

This also helps train my body to utilize fat for energy instead of relying on glucose from quick-ingesting carbs and protein. (Keyword: Fat-adapted)

The basic recipe for butter coffee is 1-2 TBSP grass-fed butter, 1 TBSP Wild MCT oil and a mug of fresh brewed Wild Coffee.

The MCT is unique in that it is quickly burned off for fuel and helps put your body into a state of mild ketosis. With the combination of ketones and the pure pastured butter fat, this fuel will help prevent you getting from getting tired in the early afternoon, a common occurrence for those that just get into fasting.

Butter coffee in the morning will provide many of the benefits of fasting while also giving you fuel to keep you on top of your game. It will also ease you into fasting and give your body time to adapt.

After awhile, the idea of eating whole food in the morning will seem bizarre to you. Around this time you should experiment with going without coffee or food in the morning. 

It’s a beautiful thing when you can wake up each morning and go your entire day without food or stimulants.

Conclusion

I wish you the best on your fasting journey. Let me know if you have any questions or comments. I’ll help where I can.

Remember, before you attempt any new diet or fasting protocol, please consult your doctor. All of these methods are to be used at your own risk.

I hope you’ll become interested enough in IF to give it a shot.

It really is life-changing.
