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.

      Advertising

      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 Stop Procrastinating: 11 Practical Ways for Procrastinators

        How to Stop Procrastinating: 11 Practical Ways for Procrastinators

        You have a deadline looming. However, instead of doing your work, you are fiddling with miscellaneous things like checking email, social media, watching videos, surfing blogs and forums. You know you should be working, but you just don’t feel like doing anything.

        We are all familiar with the procrastination phenomenon. When we procrastinate, we squander away our free time and put off important tasks we should be doing them till it’s too late. And when it is indeed too late, we panic and wish we got started earlier.

        The chronic procrastinators I know have spent years of their life looped in this cycle. Delaying, putting off things, slacking, hiding from work, facing work only when it’s unavoidable, then repeating this loop all over again. It’s a bad habit that eats us away and prevents us from achieving greater results in life.

        Don’t let procrastination take over your life. Here, I will share my personal steps on how to stop procrastinating. These 11 steps will definitely apply to you too:

        1. Break Your Work into Little Steps

        Part of the reason why we procrastinate is because subconsciously, we find the work too overwhelming for us. Break it down into little parts, then focus on one part at the time. If you still procrastinate on the task after breaking it down, then break it down even further. Soon, your task will be so simple that you will be thinking “gee, this is so simple that I might as well just do it now!”.

        For example, I’m currently writing a new book (on How to achieve anything in life). Book writing at its full scale is an enormous project and can be overwhelming. However, when I break it down into phases such as –

        Advertising

        • (1) Research
        • (2) Deciding the topic
        • (3) Creating the outline
        • (4) Drafting the content
        • (5) Writing Chapters #1 to #10,
        • (6) Revision
        • (7) etc.

        Suddenly it seems very manageable. What I do then is to focus on the immediate phase and get it done to my best ability, without thinking about the other phases. When it’s done, I move on to the next.

        2. Change Your Environment

        Different environments have different impact on our productivity. Look at your work desk and your room. Do they make you want to work or do they make you want to snuggle and sleep? If it’s the latter, you should look into changing your workspace.

        One thing to note is that an environment that makes us feel inspired before may lose its effect after a period of time. If that’s the case, then it’s time to change things around. Refer to Steps #2 and #3 of 13 Strategies To Jumpstart Your Productivity, which talks about revamping your environment and workspace.

        3. Create a Detailed Timeline with Specific Deadlines

        Having just 1 deadline for your work is like an invitation to procrastinate. That’s because we get the impression that we have time and keep pushing everything back, until it’s too late.

        Break down your project (see tip #1), then create an overall timeline with specific deadlines for each small task. This way, you know you have to finish each task by a certain date. Your timelines must be robust, too – i.e. if you don’t finish this by today, it’s going to jeopardize everything else you have planned after that. This way it creates the urgency to act.

        My goals are broken down into monthly, weekly, right down to the daily task lists, and the list is a call to action that I must accomplish this by the specified date, else my goals will be put off.

        4. Eliminate Your Procrastination Pit-Stops

        If you are procrastinating a little too much, maybe that’s because you make it easy to procrastinate.

        Identify your browser bookmarks that take up a lot of your time and shift them into a separate folder that is less accessible. Disable the automatic notification option in your email client. Get rid of the distractions around you.

        I know some people will out of the way and delete or deactivate their facebook accounts. I think it’s a little drastic and extreme as addressing procrastination is more about being conscious of our actions than counteracting via self-binding methods, but if you feel that’s what’s needed, go for it.

        5. Hang out with People Who Inspire You to Take Action

        I’m pretty sure if you spend just 10 minutes talking to Steve Jobs or Bill Gates, you’ll be more inspired to act than if you spent the 10 minutes doing nothing. The people we are with influence our behaviors. Of course spending time with Steve Jobs or Bill Gates every day is probably not a feasible method, but the principle applies — The Hidden Power of Every Single Person Around You

        Identify the people, friends or colleagues who trigger you – most likely the go-getters and hard workers – and hang out with them more often. Soon you will inculcate their drive and spirit too.

        Advertising

        As a personal development blogger, I “hang out” with inspiring personal development experts by reading their blogs and corresponding with them regularly via email and social media. It’s communication via new media and it works all the same.

        6. Get a Buddy

        Having a companion makes the whole process much more fun. Ideally, your buddy should be someone who has his/her own set of goals. Both of you will hold each other accountable to your goals and plans. While it’s not necessary for both of you to have the same goals, it’ll be even better if that’s the case, so you can learn from each other.

        I have a good friend whom I talk to regularly, and we always ask each other about our goals and progress in achieving those goals. Needless to say, it spurs us to keep taking action.

        7. Tell Others About Your Goals

        This serves the same function as #6, on a larger scale. Tell all your friends, colleagues, acquaintances and family about your projects. Now whenever you see them, they are bound to ask you about your status on those projects.

        For example, sometimes I announce my projects on The Personal Excellence Blog, Twitter and Facebook, and my readers will ask me about them on an ongoing basis. It’s a great way to keep myself accountable to my plans.

        8. Seek out Someone Who Has Already Achieved the Outcome

        What is it you want to accomplish here, and who are the people who have accomplished this already? Go seek them out and connect with them. Seeing living proof that your goals are very well achievable if you take action is one of the best triggers for action.

        9. Re-Clarify Your Goals

        If you have been procrastinating for an extended period of time, it might reflect a misalignment between what you want and what you are currently doing. Often times, we outgrow our goals as we discover more about ourselves, but we don’t change our goals to reflect that.

        Get away from your work (a short vacation will be good, else just a weekend break or staycation will do too) and take some time to regroup yourself. What exactly do you want to achieve? What should you do to get there? What are the steps to take? Does your current work align with that? If not, what can you do about it?

        10. Stop Over-Complicating Things

        Are you waiting for a perfect time to do this? That maybe now is not the best time because of X, Y, Z reasons? Ditch that thought because there’s never a perfect time. If you keep waiting for one, you are never going to accomplish anything.

        Perfectionism is one of the biggest reasons for procrastination. Read more about why perfectionist tendencies can be a bane than a boon: Why Being A Perfectionist May Not Be So Perfect.

        11. Get a Grip and Just Do It

        At the end, it boils down to taking action. You can do all the strategizing, planning and hypothesizing, but if you don’t take action, nothing’s going to happen. Occasionally, I get readers and clients who keep complaining about their situations but they still refuse to take action at the end of the day.

        Reality check:

        I have never heard anyone procrastinate their way to success before and I doubt it’s going to change in the near future.  Whatever it is you are procrastinating on, if you want to get it done, you need to get a grip on yourself and do it.
