Buchinger fasting

The study investigated the safety and possible changes in basic health and well-being indicators during Buchinger period fasting in a specialized clinic.

In a one-year observational study, 1422 participants took part in a fasting program with fasting periods of 4 to 21 days. They were divided into groups with fasting periods of 5, 10, 15 and 20±2 days. The participants followed the Buchinger guidelines with a daily calorie intake of 200-250 kcal and a moderate lifestyle program. Clinical parameters as well as side effects and well-being were documented daily.

Significant reductions in weight, waist circumference and blood pressure were observed, as well as positive effects on blood lipids, glucose regulation and other health-related blood parameters. Fasting led to a decrease in blood glucose levels and anincrease in keto body levels, documenting metabolic health. An increase in physical and emotional well-being and the absence of feelings of hunger supported the feasibility of prolonged fasting.

The results show that periodic fasting according to Buchinger from 4 to 21 days is safe and well tolerated, improves well-being and influences relevant cardiovascular and general risk factors as well as subjective health complaints.
