Why water fasting offers the deepest detox
There are countless diets, techniques and fads designed to help you detox. Many of these can certainly help, but if you’re really serious about cleansing, the most powerful method is and always has been water fasting (as well as dry fasting).
Why? Because only through sustaining a zero caloric intake can you fully unlock the body’s healing metabolism. This takes place in two steps.
The first level of cleansing: a rest from digestion
The first level of cleansing begins after your body has finished digesting its last meal. In this respect, what you eat impacts considerably. While most fruit and vegetables require only an hour or two to digest, meat takes much, much longer – even a day or two. Clearly, this is reflected in the amount of energy required for digestion, with the average diet accounting for a quarter to a third of the day’s total energy needs. So, for example, if you eat 2000 calories per day, about 600 calories of this goes simply towards digesting your food. When you stop eating, though, the energy normally used for digestion is freed up, and your body applies this to cleansing instead. That’s a lot of energy!
Taking a rest from digestion also conveys another benefit, by unleashing the full strength of your immune system. In everyday life, approximately 70-80% of the cells comprising the body’s entire immune system reside in the gut wall. This may seem surprising, but there’s a good reason for this. Every single time you eat, you also ingest potentially harmful pathogens which are liable to be absorbed through the gut wall, along with nutrients, into the blood. By leaving your digestive system in peace through a water fast, however, you free up this vast army of defense cells which are otherwise tied down your whole life. Instead of chasing down foreign invaders in the gut, cells from your immune system can now spread through the entire body to do their job. This can happen only through water fasting. Clearly, no juice fast or other cleanse which involves eating allows the possibility of such a systematic detox.
The second level of cleansing: ketosis
The second and much deeper level of cleansing begins once your body has entered the fat-burning metabolism called ketosis. This occurs only once your glycogen stores are depleted after approximately the first 24 hours of fasting (described in greater detail in the articles about one-day water fasts and three-day water fasts). The reason that ketosis is so important for cleansing is that many toxins are normally immobilised and stored in adipose tissue (fat cells), where they can’t interact with the body, causing damage. The beauty of fasting is that ketosis releases these toxins at a time when the immune system is already hugely strengthened (see above), and is thus able to safely excrete them once and for all from your body.
In everyday life, toxins accumulate because your immune system is tied down in the gut, and your kidneys and liver are already busy removing the toxic byproducts of digestion. The best your body can do is round up other toxins and pack them away in a safe place, saving their removal for a ‘rainy day’. If you don’t ever fast, though, your fat cells will eventually fill up with toxic junk. From this point onwards (usually sometime in middle age), toxins have no safe place to go. Instead they begin to circulate freely through the body, causing damage and eventually illness. This is arguably one of the reasons why, in the vast majority of cases, chronic disease is associated with middle and old age.
This whole process also explains why people on ketogenic (low-carb) diets falsely believe that their diet is cleansing. Given the prevailing but unfortunately overly simplistic view, it’s easy to equate any and all ketosis with cleansing. But given that the immune system is tied down in the gut, given that the kidneys and liver are fully occupied removing the toxic byproducts of digestion, given that most ketogenic diets require a large amount of energy for digestion in the first place, deeper detox simply cannot happen. Even beyond this, the ketosis fired by low-carb diets tends to involve only a fraction of the body’s total adipose tissue. That is, the same fat cells are used over and over again like a fuel tank, depleted and then replenished with fuel from the next meal. This means that most adipose tissue in the body is left untouched by the ketosis of low-carb diets, with no possibility for being cleansed in the first place. This is borne out by recent research which associates most low-carb diets with higher mortality rates than average. One study published in the Lancet (2018), for instance, concluded that non-vegan ketogenic diets could reduce lifespan by up to four years.
The time to fast and cleanse is now!
Unless you happen to live far from human civilisation, the air you breathe is full of carcinogens. Unless you drink water fresh from a mountain spring, the liquid which constitutes 70% of your body weight is full of chlorine, the recycled hormones from contraceptive pills, not to mention a plethora of industrial waste products. Unless you eat fully organic food, your food is contaminated with pesticides, fungicides and fertilisers. If you eat meat and dairy products, you can also count on ingesting large quantities antibiotics and artificial growth hormone. Unless you fully avoid Western medical drugs, you can add the bitter pill of allopathic medicine, along with the toxic residues it leaves behind in the body. For ultimately, every drug is a poison – this is why overdosing can kill you. Let’s face it, mankind has poisoned himself along with the planet. Do you really believe you can escape this?
The fact is, we are all filled with filth.
Does this shock you? I hope so! Like it or not, you are going to need to detox at some point in your life. It’s just a question of when. The fact is that the human body is incredibly resilient, and it usually takes half a lifetime for your fat cells to fill with toxins to the point of saturation. But then, like a boat taking on water, there does come a tipping point. The boat begins to sink. Like most people, you can ignore the situation and wait until illness strikes. At this point, it’s often too late. Or you can begin now.
When I was young, the thought of cleansing didn’t even cross my mind. To me, it was something that neurotic health maniacs did. Then I tried out water fasting and, to my shock, witnessed the filth leaving my body. My breath stank. My sweat stank. My urine stank. My tongue turned a pasty white and began to literally froth, producing a bitter, metallic taste in my mouth lasting for days. It was utterly foul. And because it was so foul, I realised how good it was to free myself from all these toxins.
From that point on, I began to honour my body with fasting. With experience, I grew more attuned to my body’s inner needs. You will too. Your body will begin to speak to you, and you’ll feel an inner urge when it’s time to fast. It isn’t something you have to force on yourself. It isn’t something you need to plan out in advance on a calendar. You’ll know when it’s time. Increasingly, you’ll look forward to that time.
Your body will love you for it.
And in return you’ll love your body back.
Unfortunately, it’s all too easy to sit on the fence – knowing and feeling that you should fast, and yet not quite reaching the point of actual commitment. It might be anxiety about hunger and detox symptoms. It might be your work schedule. Who knows. We all have our reasons, and it’s easy to find an excuse.
