Presentation
Therapeutic fasting is one of humanity's oldest practices, used since Antiquity for both spiritual and medical purposes. In naturopathy, fasting is considered a powerful detoxification tool that allows the organism to mobilize its self-healing resources. Modern scientific research has confirmed numerous biological benefits of fasting, notably stimulation of autophagy (cellular recycling mechanism recognized by the 2016 Nobel Prize in Medicine awarded to Yoshinori Ohsumi).
Water Fasting
Water fasting involves consuming only water for a determined period, typically from 24 hours to several days. It is the strictest form of fasting. After 12-16 hours without food, the body shifts to ketosis (using fat as primary fuel). Autophagy intensifies after 24-48 hours. Documented benefits include: reduced systemic inflammation, improved insulin sensitivity, stimulated growth hormone production, stem cell regeneration and enhanced mental clarity. Recommended duration in naturopathy varies from 1 to 7 days, always under professional supervision for fasts exceeding 3 days.
Intermittent Fasting
Intermittent fasting alternates eating periods with fasting periods. The most common protocols are 16/8 (16 hours fasting, 8 hours eating — most popular), 5:2 (5 normal eating days, 2 days at 500-600 kcal), OMAD (One Meal A Day), and Eat-Stop-Eat (24-hour fast 1-2 times per week). Intermittent fasting is considered more accessible and better tolerated than prolonged water fasting. Studies show benefits for weight, blood sugar, inflammatory markers and cellular longevity.
Buchinger Method
Developed by Dr. Otto Buchinger (1878-1966) in Germany, this method combines fasting with nutritive liquid intake. The protocol includes: filtered vegetable broths (250 ml twice daily), diluted fruit juices (250 ml/day), unlimited herbal teas, honey (teaspoon) and abundant hydration (2-3 L/day). This gentler approach allows prolonged fasts of 7-21 days in specialized clinics. It is highly developed in Germany, Switzerland and Russia, with structured medical oversight. Specific indications include metabolic diseases, inflammatory rheumatism and functional digestive disorders.
