Uncontrolled fasting, non-medicated fasting or a zero diet can be dangerous. Because fasting means starvation and must be monitored by a doctor. A zero calorie intake can be fatal in the worst case scenario. Fasting cures should best be carried out under medical supervision, if possible in a clinic. Fasting is not suitable as a measure for weight loss, since the organism loses fluid and degrades muscles in particular. The adipose tissue is largely retained during a short-term "fasting cure" and the dreaded yo-yo effect occurs.
Therapeutic fasting as the impetus for a healthier lifestyle
Therapeutic fasting can be an impulse for lifestyle change. The positive experience of a fasting cure can help make your whole life more health-conscious and change your eating habits. However, a fasting cure can not replace medically necessary therapy.
Many positive effects of fasting are scientifically barely or insufficiently documented. The term "purifying" which is repeatedly mentioned in connection with therapeutic fasting is scientifically unjustifiable. In a healthy human body, there is no accumulation of cinders and deposition of metabolites. Substances that can not be used are excreted via the intestine and the kidneys with sufficient fluid intake.
As a matter of principle, fasting cures should only be carried out as inpatient or under medical supervision after prior health check-up.
No weight loss agent
While fasting was originally based on religious motives, today it is often mistaken for weight loss. A wrong and sometimes even dangerous remedy: During each zero calorie intake, the organism uses the protein reserves. He also covers his needs from the heart muscles. The resulting changes can trigger cardiac arrhythmias and ventricular fibrillation. In addition, fasting can lead to acidosis (acidosis) if a "cure" lasts longer than a few days.
Fasting often leads to painful attacks of gout, as a result of which high fluid and electrolyte losses can cause low blood pressure, weakness, headache, tiredness, dry skin and mucous membranes, bad breath and increased sensation of coldness. Long-term fasting (more than five days) is also a concern because of the lack of essential fatty acids, vitamins and minerals.
Who can not fast?
Not at all fasting pregnant, breastfeeding, people with certain heart, liver or kidney disease, cancer patients, children and diabetics.
The right way
Long-term weight loss or health-promoting effects can only be achieved through a change in diet. Therefore, the German Nutrition Society recommends a high-fiber but low-fat diet, which is filling and fat deposits slowly but surely degrades.
