When fasting according to Buchinger, the daily diet consists of freshly squeezed fruit juices, broths, teas or mineral water, for example. The increase in these fluids is an important part of fasting, as the body is supplied with essential vitamins and minerals. This form of fasting goes back to Otto Buchinger, a German doctor who is considered the founder of this fasting method. Through a dosed administration of energy (a certain number of calories) the body should be purposefully detoxified and consequently regenerated; Losing weight is often a pleasant side effect. With a purification (also called detox), toxic substances or harmful products of the daily metabolism are excreted. However, fasting should not only be viewed from a physical, but also from a mental or spiritual aspect. After all, a fasting vacation should lead to a holistic improvement in health. Of course, you can also lose excess pounds with a fast.
