Lose weight with fasting or the fasting interval: how fast can fast be healthy for us?

Fasting, Basenfasten, Intervallfasten: Not suitable as a diet but good for health
Anyone suffering from hypertension or diabetes can alleviate, or even cure, their disease. However, a fasting cure is hardly suitable for weight loss, because after the end of fasting, the initial weight is usually quickly restored. Experts from the German Nutrition Society (DGE) explain how fasting works and what to look for.

Those who fast, voluntarily or completely abstain from food. In fasting, fasting often deals with their bodies, their health and their diet. Therefore, he can prepare the entry into a healthy diet.

Fasting is not suitable as a diet and does not lead to long-term weight loss. Unless the fast changes its way of life at the same time. According to the German Nutrition Society (DGE), even depending on the type of fasting, even a balanced intake of nutrients can be threatened. Older people, pregnant women, breastfeeding women, adolescents or children should refrain completely from fasting. The same applies to people with certain diseases such as eating disorders or diseases of the liver and kidneys. Healing, base and fasting at intervals are very common in this country.


Therapeutic fasting has a millennial tradition and aims to purify the body, the mind and the soul. It is used both for the prevention of health and for the treatment of certain diseases. Therapeutic fasting must be under medical supervision. A fasting cure usually takes 7 to 10 days. In addition, a day of preparation with approximately 1,000 kcal / day including abstinence from caffeine, alcohol and nicotine and after fasting for three days in order to normalize eating habits should be scheduled. During fasting days, the body is only a very small amount of maximum energy. 500 kcal / day fed as liquid food.

The beneficial effects of fasting are scientifically proven in certain diseases, such as metabolic syndrome, chronic inflammation or psychosomatic diseases. Healthy people can use this type of fasting as an introduction to weight loss; but it is not suitable for permanent weight loss.


by Basenfasten the body should be deacidified – a method commonly used in alternative medicine. Fasting staple foods should only consume foods considered basic, such as vegetables, fruits and some nuts as well as linseed oil, olive oil or high quality rapeseed. Drinks, spring water and diluted herbal teas are available. However, there is no scientific evidence of the effect of this fasting method: neither the existence of slag in the body has been proven nor the assumption that acidogenic foods disrupt the acid-base balance of the body.

Because essential nutrients can be insufficiently nourished in the long term, the DGE recommends not to fast in the long term.

fasting interval

means to abstain from food for days or hours. There are different concepts with two consecutive days of fasting or two fixed days of fasting a week or alternately. Recommendations, which foods should be selected on the remaining days, looking for fast most of the time to no avail. Intervall fasting should be used as a permanent diet. As a rule, the fasting person wants to lose weight in the long run. The rapid interval is attributed to various health benefits on the metabolism.

There is no scientific study of the long-term effects of interval fattening. Previous data suggests a positive effect on health and weight loss. The DGE does not believe that fasting at intervals makes sense to regulate its weight in the long run, as there are no concrete recommendations for food selection. There is usually no dietary change in favor of nutritionally favorable food selection.

Buchinger fasting

The change in metabolism was documented in the study by the permanent presence of ketone bodies in the urine. Fasting resulted in significant weight loss, reduced abdominal circumference, and reduced cholesterol and fat levels.

In addition, fasting normalized fasting blood pressure and improved diabetes parameters, such as blood glucose and HbA1c, improved many of the factors that contribute to cardiovascular health.

In addition, fasting improved serious health problems in 84% of cases, including arthritis, type 2 diabetes as well as fatty liver and hypercholesterolemia, high blood pressure. and fatigue.
