How Much Muscle Mass Can You Lose During a Water Fast?

How Much Muscle Mass Can You Lose During a Water Fast?

Most people in the water fasting community have no clue on how much muscle mass it’s actually possible to lose during a water fast.

At best, they can tell you that our bodies are very efficient at preserving our muscle mass during a water fast. But I have yet to meet anyone who knows the exact numbers.

In this article, I have relied on modern science to put an end to this confusion. If you read it all the way through, you will understand how much muscle mass you can expect to lose during a water fast (depending on how long you intend to fast).

But first, I want to quickly explain why we lose muscle mass during water fasting in the first place.

Why do we lose muscle mass during water fasting?

Some animals, like bears during winter hibernation, can survive without food for a very long time. And the amazing thing is, they can do it without any detectable loss of muscle mass [1].

Humans, on the other hand, we tend to lose a lot of muscle mass during starvation. Roughly put, that’s because our brains require some special “brain fuel” to survive [2].

Because we’re not eating any food during a water fast, our bodies have no choice but to start burning away some of our “structural protein” (to keep powering our hyper-intelligent brain).

Those structural proteins are the very basic building blocks of your muscles, which means you’re bound to destroy some of your muscle mass during a water fast.

Explaining all this in great detail would be beyond the scope of this article. So let’s just take a look at how much of those structural protein you can expect to lose during a water fast.

The daily loss of structural protein on a water fast

In one starvation study [3], they measured the amount of protein obese people lost during a 21-day water fast.

I’ve adapted the data from that study into this daily protein loss chart:

Daily loss of structural protein during water fasting

    You can see that on the 1st day of the water fast (the first bar on the left), the loss of structural protein was the highest (69 grams).

    By the end of the 21-day fast (the last bar on the right), the loss of structural proteins was reduced by almost 80% (to 15 grams).

    This shows that our bodies can adapt to starvation extremely well. In order to keep you alive as long as possible, your body keeps slowing down the destruction of your vital body mass.

    But ultimately, you’ll lose much more muscle mass than this small amount of structural protein.

    Why?

    Because your muscle tissue is actually made of only about 20% of protein, while the rest of it is water [4].

    The total loss of muscle mass on a 21-day water fast

    Here’s another chart I’ve created based on that 21-day starvation study:

    Total loss of vital body mass during water fasting

      This chart shows the total vital body mass you can expect to lose (in pounds), depending on how long you plan on fasting.

      If you plan to fast for 6 days (bottom axis), the chart can tell you that you could be losing a little over 6 pounds of your vital body mass (left axis).

      If you plan on doing a 13-day water fast, you could lose a little over 10 pounds of your vital body mass and a 21-day water fast could set you back by full 13 pounds of vital body mass.

      While this chart can tell you how much vital body mass you can expect to lose during a water fast, it can’t tell you how much total weight you can expect to get rid of.

      Maybe you already picked up on this, but I am no longer talking about muscle mass.

      Instead, I keep talking about your “vital body mass”, so let me quickly explain the difference between the two.

      You lose much more than just your muscle mass

      When it comes to understanding your final weight loss results after a water fast, things can easily get a bit confusing.

      Just take a look at all the different kinds of weight you’ll end up losing if you decide to do a water fast.

      A breakdown of your final water fasting weight loss results

        At the highest level, you will be losing your body fat mass and your lean body mass (also called non-fat, or fat-free body mass).

        The lean body mass you lose will include some of your sodium and glycogen bound water weight, and some of your vital body mass.

        And finally, the vital body mass you lose will include more than just your muscle mass.

        Because some of those protein, the basic building blocks of your vital body mass, will also come from your vital organ tissue [5].

        And what’s the biggest problem when it comes to destroying the basic building blocks of both your muscles and vital organs?

        Remember, the most important muscle and vital organ in your body that could suffer because of this, is your heart.

        I won’t get into more detail here, but you can read all about the health dangers of water fasting here).

        Advertising

        Now, let’s look at some of the things you can do to avoid losing your vital body mass while fasting.

        How to prevent the loss of muscle mass during fasting?

        The most obvious solution to avoid the destruction of your vital body mass is not to do a fast in the first place. If you were considering doing a water fast for weight loss, you can simply go with any of the countless less restrictive diets out there.

        Just make sure to do your research, because not all weight loss diets are designed to protect your vital body mass.

        But if you’re still interested in going through with a water fast, at least consider looking into intermittent fasting, alternate day fasting, or even muscle sparing fasting as safer alternatives to water fasting.

        Muscle sparing fasting, for one, can actually be done without any solid food and can give you that “pure” feeling of fasting (while still helping you avoid that unnecessary destruction of your vital body mass).

        My goal for this article was to help you understand water fasting is no fairy tale. Knowing that you could actually destroy up to 13 pounds of muscle mass AND vital organ tissue (on a 21-day water fast), you’re hopefully going to at least consider the alternatives.

        Now, I want to ask a small favor of you. If you know absolutely anyone who has ever done, or has at least considered doing a water fast, please share this article with them.

        Don’t do it for me, or even for yourself. Do it for them and for their safety.

        How to Overcome Boredom

        How to Overcome Boredom

        Have you ever been bored? Restless? Fidgety? In need of some inspiration?

        I have a theory on boredom. I believe that the rate of boredom has increased alongside the pace of technology.

        If you think about it, technology has provided us with mobile phones, laptops, Ipads, device after device – all to ultimately fix one problem: boredom.

        What is Boredom?

        We have become a global nation that feeds on entertainment. We associate ‘living’ with ‘doing’. People now do not know how to sit still, and we feel guilty when we are not doing anything. Today, inactivity has become the ultimate sin.

        You might not realize it, but boredom stimulates a form of anxiety and stress. It evokes an emotional state that creates frustration and feeds procrastination.

        It’s a desire to be ‘doing something’ or to be ‘entertained’ – it’s a desire for sensory stimulation. What it boils down to is a lack of focus.

        If you think about those times when you’re bored, it’s usually because you did not know what to do. So, indecision also plays a big part.

        When we are focused on what’s important to us and what we want to achieve, it’s pretty hard to be bored. So, one answer to boredom is to become focused on what you want.

        Sometimes It’s Good to Be Bored

        If boredom is a desire for sensory stimulation – then what’s the opposite of that? To be content with no stimulation – in other words – to enjoy stillness.

        Sometimes, it’s not boredom itself that causes the frustration but the resistance to doing nothing.

        Advertising

        Think about it. What would happen if you were to ‘let go’ of the desire to be entertained? You wouldn’t be bored anymore, and you will feel more relaxed!

        In my experience, it’s often the most obvious, simplistic solutions that are the most powerful in life. So, when you’re bored, the easiest way to combat this is to enjoy it.

        It may sound weird but think of ‘boredom’ as a form of ‘relaxation’. It’s a break from the constant stimulation that 21st-century living provides – constant TVs, mobile phones, radios, internet, emails, phone calls, etc.

        Who knows, maybe ‘boredom’ is actually good for us?

        Next time you’re ‘feeling bored’ instead of feeding the frustration by frantically looking for something to do, maybe you can sit back, relax, and savor the feeling of having nothing to do.

        Advertising

        In this article, I’ll share with you my 3-step strategy on how to overcome boredom.

        3-Step Strategy to Overcome Boredom

        1. Get Focused

        Instead of chasing sensory stimulation at random, focus on what’s really important to you. Focusing on something important helps prevent boredom because it forces you to utilize your time productively.

        You should ask yourself: what would make good use of your time? What could you be doing that would contribute to your major goals in life?

        Here are a few ideas:

        • Spend some time in quiet contemplation considering what’s important to you.
        • Start that creative project you’ve been talking about for the last few weeks.
        • Brainstorm: think of some ideas for new innovative products or businesses.

        2. Kill Procrastination

        Boredom is useful in some ways because it gives you the energy and time to do things. It is only a problem if you let it. But if you use it to motivate yourself to be productive, then you can more easily overcome boredom.

        So, the next time you’re bored, why not put this good energy to use by ticking off those things that you have been meaning to get done but have been too busy to finish? This also presents a great time for you to clear your to-do list.

        Here are some ideas:

        • Do some exercise.
        • Read a book.
        • Learn something new.
        • Call a friend.
        • Get creative (draw, paint, sculpt, create music, write).
        • Do a spring cleaning.
        • Wash the car.
        • Renovate the house.
        • Re-arrange the furniture.
        • Write your shopping list.
        • Water the plants.
        • Walk the dog.
        • Sort out your mail & email.
        • De-clutter (clear out that wardrobe).

        3. Enjoy Boredom

        If none of the above solutions work, then you can try a different approach. Don’t give in to boredom and instead choose to enjoy it. This doesn’t mean allowing yourself to waste your time being bored. Instead, think of it as your time to relax and re-energize, which will help you be more productive the next time you work.

        Contrary to popular belief, we don’t need to be constantly doing things to be productive. In fact, research has shown that people are more productive when they take periods of rest to recharge.[1] Taking breaks once in a while helps boost your performance and can help make you feel more motivated.

        So, take some time to relax. You never know, you might even like it.

        Final Thoughts

        Learning how to overcome boredom may be difficult at the beginning, but it can be easier if you make use of some techniques. You can start with my 3-step strategy on how to overcome boredom and work your way from there. So, ready your mind and make use of these tips, and you will be overcoming boredom in no time.
