When we fast we have to make sure that our body is ok.

Fasting and Kidneys

The kidneys filter out waste products from the blood and excrete those into the urine. The kidneys also regulate the levels of electrolytes in the blood, the pH balance and blood pressure. The kidneys also produce certain hormones. Hormones are chemicals that regulate specific body functions and health.

The body uses the sugar glucose as its source of energy. If we cease to eat, or are eating less and our food does not supply the amount of energy that our body is using, we gradually run out of glucose. The body then uses glucose storage glycogen, and when glycogen runs out the body breaks down fat for energy. When the person runs out of fat to burn, the body spends proteins for energy source. By the time when the body is using protein for energy, we say that the body is no longer fasting, it is starving.

Starvation can lead to kidney failure. "Kidney failure" sounds like the kidneys dying, but is actually the name for kidneys not functioning properly. Kidney failure means that the filtration rate of the kidneys is impaired and reduced and the kidneys are unable to carry out their filtration properly. Waste products and toxins may accumulate in the blood stream. If high levels of urea accumulate in the blood, symptoms appear such as vomiting or diarrhea, nausea, weight loss, nocturnal urination, more frequent urination or of unusually larger amount and pale color, or less frequent urination in smaller amounts and dark color. Blood in the urine, or feeling a pressure or difficulty urinating.

Abnormal fluid levels in the body or inappropriate pH. Abnormal levels of potassium, calcium or phosphate. Buildup of potassium in the blood can cause abnormal heart rhythms and muscle paralysis. A buildup of phosphate can lead to itching, bone damage, or muscle cramps due to low levels of calcium.

Kidney failure can cause proteins from the blood, which are normally too large to pass, to enter into the urine, causing the urine to become foamy or bubbly as well as swelling in the hands, feet, abdomen, or face; the condition is called proteinuria.

Failing kidneys may produce less of the hormone erythropoietin, a hormone that stimulates the production of red blood cells. Less of the hormone means fewer red blood cells are produced, leading long-term to anemia. Anemic blood cannot carry enough oxygen, resulting in the person feeling tired, weak, to have memory problems, difficulty concentrating, dizziness, and low blood pressure, possibly due to insufficient oxygen to tissue which in turn means that the body is unable to use oxygen to convert glucose or other energy source chemicals into energy.

Kidney failure can also cause a loss of appetite. A bad taste in the mouth. Difficulty sleeping. Darkening of the skin.

Causes of kidney failure (that are relevant to fasting or starvation) include the kidneys being overloaded with toxins, or insufficient blood supply to the kidneys. There are two forms of kidney failure: acute, and chronic. Kidneys can recover from acute kidney failure and return back to normal although with some risk of relapse. Chronic kidney failure is far more serious and might not be reversible. The two most common causes of chronic kidney failure are diabetes mellitus and uncontrolled long-term high blood pressure. Severe cases of chronic kidney failure require dialysis or a kidney transplant.

People can buy a simple blood testing kit for home to test their levels of creatinine in the blood. Its reading can then be converted into a measure of kidney function. Creatinine is a toxic substance which healthy kidneys excrete from the blood. Elevated levels of creatinine may indicate kidney failure.


I am no expert on topics of health and would like to do a lot more in-depth study into the topic of kidneys, fasting and health, but one thing that is striking is that many of the physical symptoms that indicate to kidney failure are ones that many in the Breatharian culture interpret as being good signs of detoxification. I am however not convinced that these symptoms are beneficial or that they be signs that the body is cleaning itself.

The bad taste in the mouth, frequent urination of small amounts and dark urine, weakness, problems with concentration, dizziness, memory problems, are typical symptoms that people experience when they are doing a fast that is intended to be part of activation of Breatharianism. I do not believe that these symptoms are signs that the body is cleaning itself or that it is improving itself, it is more than likely signs that the body is dehydrated and that the kidneys are not functioning properly.

The problem is that Breatharianism is a physiological condition which seems to be activated mentally by the person by means of the collective of their thoughts, emotions, intentions, and beliefs, which seems to regulate the physical body into a state where it is able to endure prolongued periods of fasting, whereas without that mental stimulus the body would enter into all the typical conditions of starvation and dehydration. But not all who attempt Breatharianism are able to mentally activate it and so they have these typical symptoms of dehydration and starvation when they attempt to fast, but the problem is that many will then dismiss the seriousness of their symptoms and call them detoxification.

Real Breatharianism does not involve these symptoms. I cannot advise anyone to attempt Breatharianism because of the many health risks, yet still there is such a physiological phenomenon as Breatharianism so it still deserves to be discussed. It is important that you do not end up with protein deficiency or dehydration. Take care of the kidneys and body.
