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).

        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.

        11 Hidden Benefits of Using Oil Diffusers

        11 Hidden Benefits of Using Oil Diffusers

        Affordable, relaxing, and healthy, oil diffusers are gaining popularity with people everywhere due to their extensive benefits. Oil diffusers work through the simple process of oil diffusion, which uses heat to turn oil into a vapor that is then spread around a living space. Diffused oil can have several relaxation and health-related benefits, including safe scent-dispersion, mosquito and mold defense, stress relief, and more!

        Read on for 11 hidden benefits of using oil diffusers.

        1. Safe Scents That Make Sense

        Unlike candles or air fresheners, oil diffusers release cleansing molecules into your air that work to purify it, not overload it with unhealthy chemicals. Electronic diffusers also do not pose the fire risk that candles do. Plus, they contain the added feature of interchangeability, which means you change oil types for different scents and health benefits.

        2. Stress Relief

        Several lab studies have confirmed that diffusing essential oils like lavender have been shown to reduce stress and help relieve anxiety in medical patients. Preliminary studies have also shown that oil diffusers can help alleviate symptoms of depression.

        3. Improved Sleep

        Diffused oil has relaxing properties that can help people of all ages fall asleep quicker and sleep more soundly. Electronic diffusers not only have the option to mix and match different oil blends (Try a lavender, Bulgarian rose, and Roman chamomile blend to help with insomnia), they also run at a gentle hum that helps relax an agitated mind. Many also come with an auto shut-off feature to help conserve oils once you have fallen asleep.

        4. Appetite Control

        Much like gum, oil diffusers can help stimulate the senses in a way that works to curb appetite. New research has shown that diffused peppermint oil can help curb appetite by inducing a satiety response within the body. Diffused peppermint oil has also been shown to increase energy.

        5. Bacteria and Mold Killing

        When essential oils are diffused in the air, they break down free radicals that contribute to the growth of harmful bacteria. Eucalyptus, thyme, and tea tree oils are especially good for this purpose. Diffused oil is also highly effective when it comes to combating fungal yeast threats, as the oil help makes the air inhospitable for yeasts such as mold. Pine and red thyme essential oils are best for combating mold.

        6. Decongestion and Mucus Control

        Ever tried Vick’s Vapo-Rub? Its decongesting powers come from active ingredients made from the eucalyptus tree. In principle, oil diffusers work the same way as Vapo-Rub, except they diffuse their decongesting vapor all around the room, not just on your chest or neck. Oil diffusers have been known to cure pneumonia in lab mice.

        7. Mosquito Repellant

        Nobody likes mosquitoes — but when the trade-off means using repellants full of DEET, a toxic chemical that can be especially harmful to children, mosquito control can often seem like a lose-lose. However, scientists have shown that oil diffusers can be used as a safe and highly effective mosquito repellant. Studies have shown that a diffused oil mixture containing clove essential oil and lemongrass essential oil repelled one type of Zika-carrying mosquito, the Aedes aegypti mosquito, at a rate of 100%.

        8. Pain Relief

        While applying oils directly to areas of your body may be the most effective way to alleviate pain, diffusing essential oils can also be an effective means of pain relief. When we inhale healthy essential oils, they enter our blood stream and can help internally relieve persistent pain from headaches, overworked muscles, and sore joints.

        9. The New Anti-Viral

        Research into the anti-viral effects of oil diffusion is now just gaining steam. A recent study showed that star anise essential oil was proven in medical experiments to destroy the herpes simplex virus in contained areas at a rate of 99%. Another study showed the popular DoTerra oil blend OnGuard to have highly-effective influenza-combating powers.

        10. Improved Cognitive Function

        Diffusing essential oils has also been shown to improve cognitive function. Many essential oils have adaptogenic qualities, which can work twofold in soothing us when we’re stressed, and giving our bodies a pick-me-up when we’re feeling down or sluggish. By working to level out an imbalanced mood, diffused oils also help us to focus. There are also several essential oils which have been shown to help balance the body’s hormones. With prolonged use, these oils can work to repair the underlying causes responsible for hindering cognitive function.

        11. Money Saving

        With ten clear benefits of oil diffusers already outlined, there is one more that should now be obvious: using an oil diffuser will help you to save money. As an anti-viral, bug repelling, and stress-relief solution rolled into one safe product, an oil diffuser used with the proper oils will save you money on products you might otherwise be buying to help cure those pesky headaches or get your kids to fall asleep on time. If you’re wondering just how affordable oil diffusers can be, check the buyer’s guide to the best oil diffusers — you’ll be sure to find one that fits your budget!
