Fasting (intermittent fasting) as a potential detoxification or health management method, its specific steps and precautions need to be scientifically adjusted according to the individual's physique. The following are step-by-step instructions and professional advice： ###解析 Step analysis (take 24-hour clear water fasting as an example) 1. **Pre-preparation (24 hours before fasting)** -Dietary adjustment: Gradually reduce caffeine, refined sugar and processed foods, and increase vegetables, high-quality protein and whole grains. -Physical reserves: Choose digestible foods (such as quinoa salad + steamed fish) for dinner the day before. -Item preparation: more than 2000mL of mineral water/purified water, sugar-free electrolyte tablets (sodium/potassium/magnesium) are available. 2. **Fasting execution stage** - **6:00-8:00**： Drink 500mL of warm water after getting up (add a little lemon juice to stimulate bile secretion). -**All weather**： -Replenish 100-200mL of water every hour (in small quantities and multiple times), and the daily drinking amount must reach body weight (kg)×30mL. -Any calorie-containing foods, including sugar-substitute beverages, are prohibited; sugar-free black coffee/tea is allowed (use with caution for patients with stomach problems). -Monitor body signals: if you experience dizziness or palpitations, you need to stop immediately (it may be a sign of hypoglycemia). 3. **Re-eating stage (key link)** -First meal (within 30 minutes after the end of fasting)： It is recommended to drink 100mL of coconut water (to replenish electrolytes) → after 30 minutes, eat flowing food (such as rice oil and vegetable soup). - Follow-up 6-8 hours： Gradually introduce soft foods (steamed eggs, fruit puree) and avoid high-fat and high-fiber foods. -After returning to a normal diet the next day, give priority to supplementing fermented foods (sugar-free yogurt, kimchi) to repair the intestinal flora. ###️️Risk warning (the following people are strictly prohibited from trying) -Pregnant/lactating women -Patients with BMI<18.5 or a history of eating disorders -Diabetics (especially insulin-dependent) -Those with adrenal fatigue or HPA axis dysfunction ### 科学Scientific alternative The World Organization of Gastroenterology (WGO) pointed out that the human body itself has a complete detoxification system (liver, kidneys, intestines). Safer ways to "detox" include： 1. Daily intake of 25-30g dietary fiber (such as 10g of chia seeds + 1 apple) 2. Intermittent high-intensity exercise (HIIT) 2 times a week to promote lymphatic circulation 3. Guarantee 7-9 hours of deep sleep at night (promote cerebrospinal fluid to remove metabolic waste) ### 研究 Research data reference -Research in the journal "Cell" shows that short-term fasting may induce autophagy of damaged cells (effective in animal experiments within 72 hours) -Meta analysis in the Journal of the American Medical Association (JAMA) pointed out that the weight loss effect of 16:8 light fasting is better than continuous fasting. It is recommended that first-time testers start with a 12-hour fast (such as after dinner to breakfast the next day) and gradually extend it. It is recommended to undergo a basic physical examination before implementation (focusing on fasting blood sugar and liver function indicators).
