Deacidification, ketosis, intermittent fasting, free radicals … Do you hear thunder in Cologne? Then we have an overview ready for you with the most commonly used terms in detox country!


Acidification means too high an acid level in your blood. It should have a pH between 7.35 and 7.45. When your blood gets a lower pH (acidifies), your body will restore it. This can be done by excreting the acidic substances through respiration or through the urine. Your body can also extract basic substances from the bones to raise the pH of the blood.

Our current diet contains a lot of acidic foods, with a low pH. This causes chronic low-grade metabolic acidification. Your blood is not acidified, because your body ensures that your blood always has the correct pH value. But this comes at a price, for example, the extraction of calcium from the bones. Chronic acidification also causes inflammation, reduced resistance and joint damage. An ideal diet has 80% basic substances and 20% acidic.

“Long-term consumption of a very acidic diet results in metabolic acidosis, an acidification of the total body system”

The pH value is also very important for your intestines. For example, digestive enzymes in the intestine are activated at a pH higher than 7. At a lower pH you get poor digestion and the nutrients are no longer properly absorbed by the intestines. Due to poor digestion, semi-digested residues remain, which can provoke inflammation.


Free radicals and antioxidants

Free radicals are released during our natural metabolism. On the other hand, external factors (alcohol, smoking, stress, unhealthy food or environmental pollution) cause that we come into contact with free radicals. These free radicals are looking for a missing electron in our cells, damaging our healthy cells and energy production.

The higher the number of free radicals in our body, the more healthy body cells lose their effect. We call the result “oxidative stress”. Your body cells can be irreparably damaged. The chance of negative consequences for your body (pigment spots, cancer or rheumatism for example) is therefore increased. We can also see aging as a form of oxidation. Free radicals attack your connective tissue, making your skin less elastic.

“The higher the number of free radicals in our body, the more healthy body cells lose their effect. We call the result “oxidative stress”. “

On the other hand, we also need these free radicals in our body. They trigger our body to stimulate inflammation. For example, when we suffer from flu, our body must be able to do its work!

To limit the damage from free radicals, our body needs antioxidants. These can neutralize the composition of (harmful) free radicals again. A healthy, balanced diet (a menu rich in vegetables, fruit, fish and nuts) and a healthy lifestyle are a good start.


Toxins & detoxification

To understand detox, we first explain what toxins are and then how we can get rid of them.

Toxins include phthalates, metals, forest phenol, PCBs,… which you ingest, often through your diet. Normally, your body can drain them itself. But if too many toxins get in, they are stored around your fat cell. This means that the fat cell is no longer available for combustion. In addition, toxins increase the free radical load, which has a negative effect on your metabolism.

“If too many toxins come in, they are stored around your fat cell. This means that the fat cell is no longer available for combustion. ”

In order to detoxify the body, the lymphatic system absorbs all waste and toxins and transports it to the liver. She will in turn process them and then determine how they will leave the body. Think of the liver like the air conditioning filter in your house. You know it’s time to replace or clean it when it gets dark and clogged. In this state, the filter can no longer keep your home free from things like dust, pet dander, dirt, and toxins. Before the liver gets into a similar state, it’s time to clean it of the toxic residues that have built up over time. This also gives the liver time to heal itself.

When the liver is ‘clogged’, the waste and toxins are no longer excreted, but transported to the fat cells in the abdomen. Once there, they hook themselves onto a cell. To keep them there, the body will make a protective layer around it. As a result, the fat cell is no longer “accessible” for fat burning. This creates an unhealthy situation in which our immune system weakens and we are more susceptible to diseases and inflammation.

If the liver functions optimally again, for example through a liver cleanse, it will “open the doors”, send out special hormones to dissolve the layers of insulation and transport the waste and toxins back to the liver. From that moment on, the body switches to good belly fat burning and we start to excrete the toxins.



Fasting is taking less or no food for a longer period of time. You can do this, for example, by intermittent fasting. When fasting, you take less than 600 calories a day. This is because studies on the positive effects of fasting have been conducted with between 500 and 650 calories per day.

“Fasting prevents diabetes, heart disease, cancer and obesity.”

The beneficial effects that occur with a low calorie intake? Your body will break down and recycle old cells. Fasting also decreases the production of IGF-1. High IGF-1 is associated with faster aging and an increased risk of cancer. In addition, it lowers blood sugar, improves insulin sensitivity and prevents diabetes, heart disease, cancer and obesity.


Colon cleanse

An unhealthy diet and a passive lifestyle can cause the intestines to no longer function optimally. This creates an imbalance in the intestinal flora with overweight, depression, Alzheimer’s, allergies,… as possible consequences. When they function properly, our food can be properly digested and all nutrients are properly absorbed. Our intestines therefore fulfill a very important function!

A bowel cleansing will remove residues that do not belong in the intestines, so that inflammation and pathogens do not stand a chance and the functioning of your intestines will be optimal again. After the intestinal cleansing it is important to take probiotics, so that the intestinal flora is restored.

“This creates an imbalance in the intestinal flora with overweight, depression, Alzheimer’s, allergies, … as possible consequences.”

You can perform a colon cleanse in different ways. You can book colon hydrotherapy. The large intestine is repeatedly cleaned by warm water. This treatment is performed by a therapist. You can also clean your bowels by using Epsom salts, which makes the stools watery and will rinse out the remains. Senne tea also rinses the intestines in this way. Or you can opt for a bowel cleaning kit, in which you will find oxi powder that cleans your intestines, and probiotics to rebuild the bacterial flora.


Low Carb & Ketosis

When you eat carbohydrates, your blood sugar (glucose) rises. When you eat too many carbohydrates, your cells are full of glucose and glucose can remain in your blood. Glucose in the blood clogs the veins, causes inflammation, …

Almost all carbohydrates are stored as fat. Insulin is the hormone that carries glucose to the fat cells. When you eat too many carbohydrates, the insulin in your blood rises. In high doses, insulin is toxic, causing cell damage, cancer and atherosclerosis, nerve damage and pain in the extremities. In addition, a consistently high level of insulin causes the cells to stop responding to insulin. This is called insulin resistance and can lead to type 2 diabetes and heart disease, Alzheimers etc.

“A detox is the ideal way to switch your body from carbohydrate burning to fat burning (ketosis).”

Insulin resistance makes the body believe that not enough glucose is stored in the cells and sends the signal to start using muscle mass to make glucose. Result? You lose muscle mass and get fatter. Instead of feeling energized after eating, you feel tired and in need of more carbohydrates. Because you now also have less muscles, exercise becomes heavy and you end up in a vicious circle. A detox is the ideal way to switch your body from carbohydrate burning to fat burning (ketosis).
