What Is Water Fasting?
Water fasting is a strict weight loss diet where you fast or do not consume any other food (both solid and liquid foods) but water. This means you cannot consume tea, coffee, or gum. However, if you are sick or if you do not have the adequate nutrient reserve to go through the day on just water, you may take some liquids such as coffee, tea, or your multivitamins. However, if you do not have any medical condition and you have excellent nutrition, then we recommend you stick with this strict diet.
It is recommended that water fasting lasts anywhere from 24 to 72 hours, and if you are looking to go beyond the 72-hour limit, then we highly recommend you do so under strict supervision.
There are various reasons why someone may attempt water fasting besides weight loss. Some water fast to prepare for surgery (usually they water fast for 12 hours), others water fast as a way of spiritual purification, while others fast to detox their body.
How Does Water Fasting Work?
First of all, you are considered to be fasting when you do not eat any food from 12 hours to a month after your last meal. This means anything below 12 hours isn’t considered fasting.
When we eat, our body stores energy in the form of fats and sugars. Sugar (glucose) is used as the body’s immediate source of energy for our day-to-day activities, and the fat, on the other hand, is stored to be used when necessary. As we continue to eat, these fats are continuously stored and they accumulate and cause us to gain weight.
So, when we fast, our body immediately uses up all the glucose, and when the glucose is finished, and there is no food in the stomach to be digested, then the ghrelin (the hunger hormone) sends a signal to the brain to indicate that you are hungry. Well, when this happens, the brain causes you to feel hungry, and when you do not eat for 12 hours, the body then readjusts and then goes into survival mode to feed itself.
Since there is no food for the body to digest for energy, the only way the body has to feed itself is by breaking down stored fat and also, some muscle to produce energy, and this process is known as lipolysis. And when this process starts, you will realize that you do not feel hungry, even though you aren’t eating.
What Are Some Benefits Of Water Fasting?
There are tons of benefits associated with water fasting.
1. You Produce BDNF
The Brain-Derived Neurotrophic Factor is an essential brain protein that is boosted when the body is under stress. When this protein is triggered, it causes our body to produce new neurons or brain cells. Besides producing new neurons, BDNF also protects existing neurons from neurodegenerative disorders such as Alzheimer’s and Parkinson’s diseases.
The body producing new brain cells due to BDNF can be helpful to those with cognitive issues, less focus, and memory problems. There are various ways you can boost BDNF, however, fasting is one of the most effective ways to do so.
Studies have shown that fasting produces 3.5 times more BDNF than exercise does. The catch here is that you would need to fast for more than 48 hours for your body to induce the production of BDNF.
So, how does fasting produce BDNF?
When the body notices that there is no food coming in, the body and brain get stressed as a result. When this happens, the body has to find a way to counter the stress produced by the brain. And to counter this stress, the body stimulates the BDNF protein to produce new brain cells to deal with the stress.
2. Increase In Ketones
You do not need to be on a ketogenic diet to get into ketosis. When you water fast, your body starts to produce ketones. This happens as a result of the body-switching from burning glucose to burning fat, as a result of the deficiency of glucose in the body. And when fat is burnt, ketones are produced, and as a result, we lose fat.
Ketones are an alternative form of energy to glucose, and studies have shown that ketones (BHB) are a more efficient energy source than glucose. Therefore, you can gain more energy to go about your daily activities when your body runs on ketones.
Another advantage is that ketones prevent you from consuming unnecessary calories by lowering your appetite. It achieves this by suppressing the ghrelin hormone (the hunger hormone), and when this happens, you do not feel hungry, and this means you wouldn’t feel like eating; therefore, your body will keep on burning the stored fat, which will help you lose weight.
In addition, the increase in ketones in the blood is a great stress reliever. This is a result of ketones increasing the levels of GABA in the blood and brain. Gamma-amniotic acid (GABA) is a neurotransmitter that regulates impulses between nerve cells. Studies have shown that low levels of GABA in the blood cause bad moods, stress, and depression. Conversely, when levels of GABA are increased in the blood, it boosts your mood and gives you a calming effect, which is known to help deal with depression.
Finally, ketones are great for improving cognitive function. Higher levels of ketones have been proven to lead to improvement in brain performance. Unlike other parts of our bodies such as our muscles, the brain, and heart love ketones. They run on ketones. Studies have shown that when the brain runs on ketones, it helps suppress neurodegenerative disorders. In addition, increased levels of ketones are known to help people with heart failures.
3. Helps Improve Your Skin
If you want clearer skin, then one of the ways to achieve this goal is by water fasting. Fasting has also been proven to reverse the effect of aging skin by increasing the production of collagen. And when we drink water, our skin is hydrated and we get young-looking and soft skin.
When we fast, the Human Growth Hormone gets induced into the blood, and when HGH levels increase in the blood, it causes the synthesis of the collagen protein to produce more collagen in the blood. Collagen is the protein responsible for repairing and building the skin’s tissues, hair, muscles, and ligaments.
In addition, water is an essential nutrient that gives us clearer skin. When we drink water while we fast, we get the added benefit of hydrated skin and elastic skin. In addition, when you drink water, you prevent the build of wrinkles and scars on the face.
4. Improvement In Gut Biome
Water fasting is a great way to improve your gut biome. One way water fasting helps with your gut health is the production of immunoglobulin A (IgA). IgA is an important protein that is responsible for negating the effect of bacterial toxins in the intestine.
Also, studies showed that water fasting improved the homogeneity of gut microbes.
How To Water Fast:
Water fasting is simple, all you need to do is to avoid food or any other liquid for at least 24 hours. However, if you have any medical condition, then you must visit your doctor before you try water fasting.
What Are The Dangers Associated With Water Fasting?
Even though water fasting can be beneficial, there are some risks associated with it. And in this section, we will discuss some risks associated with water fasting.
Some people that try to water fast for the first time are going to feel dizzy within the first few hours when they try to get up or engage in any activity. The dizziness is caused as a result of orthostatic hypotension, which means there is a drop in blood pressure. When this happens, you tend to feel lightheaded, and some people end up fainting.
This is why you must be healthy before you try water fasting.
2. Electrolyte Imbalances
Because we do not consume any liquid or food when water fasting, there is a deficiency in certain electrolytes of the body, most commonly sodium and potassium. And when we water for longer periods such as 48 hours to 72 hours or more, there tend to be low levels of these two electrolytes.
Sodium and potassium are essential elements responsible for regulating body fluids and blood circulation. Low levels of sodium and potassium cause us to feel fatigued momentarily, muscle cramps, and tingles; however, with time, we start to feel better because the body causes the kidney to release sodium and potassium into the bloodstream.
However, when you start noticing any of these signs, it is important that you quit your fast immediately. Or, you can supplement your fast with some electrolytes, minerals, and vitamins.
The recommended period for water fasting is between 24 to 72 hours. You can fast for more than 72 hours; however, you need to consult your doctor first before you do so. Also, fasting for more than 72 hours can lead to medical complications.
Due to the strictness and intensity of water fasting, this type of fasting isn’t for everyone. In this section, we will take a look at certain people that should avoid water fasting.
– Pregnant and breastfeeding mothers
– Diabetic Patients
– People with blood pressure issues.
– Patients with heart disease.
Also, if you have any health condition, make sure to check in with your doctor before you try water fasting.
When you are done fasting, do not want to eat any meal. It is advised that you eat a snack, a mixture of apple cider and lemon juice (especially for those fasting for 72 hours), soup, and probiotic foods.
