Continuous 21 day liquid fasting may lead to serious health risks, including muscle loss, metabolic disorders, and organ damage. The potential hazards of liquid fasting mainly include nutrient deficiency, electrolyte imbalance, decreased basal metabolic rate, degradation of digestive function, and psychological dependence.
1. Nutritional deficiency:
Long term intake of fluids alone cannot meet the human body's needs for protein, essential fatty acids, and micronutrients. Lack of vitamin B may cause neuropathy, iron deficiency can lead to anemia, and insufficient calcium intake may accelerate osteoporosis. Some liquid fasting individuals may exhibit obvious signs of malnutrition such as hair loss and cracked nails.
2. Electrolyte imbalance:
Relying solely on fruit and vegetable juice or clear soup can easily cause electrolyte imbalances such as sodium, potassium, and magnesium. Hyponatremia may cause cerebral edema, hypokalemia can lead to arrhythmia, and in severe cases, ventricular fibrillation may occur. In clinical practice, it is common for liquid fasting patients to experience dizziness, convulsions, and even coma due to electrolyte imbalance.
3. Decreased metabolic rate:
Continuous insufficient energy intake can trigger a famine mode in the body, and the basal metabolic rate can be reduced by more than 40%. The level of thyroid hormone T3 significantly decreases, and muscle tissue is extensively decomposed for energy supply. This metabolic damage may persist until 6 months after returning to a normal diet, forming a predisposition to obesity.
4. Degradation of digestive function:
Long term lack of solid food stimulation in the digestive tract can lead to reduced secretion of digestive enzymes and atrophy of intestinal villi. After resuming diet, it is easy to experience intolerance symptoms such as bloating and diarrhea. Some cases have shown that extreme liquid fasting may induce chronic gastritis or irritable bowel syndrome.
5. Psychological dependence:
The illusion of rapid weight loss can easily lead to behavioral addiction, and some people may experience anorexia or binge eating rebound. Neurotransmitter disorders may lead to emotional problems such as anxiety and depression. About 68% of extreme fasting individuals regain weight beyond their original weight after stopping.
It is recommended to adopt scientific weight loss methods, with a daily calorie intake of no less than 1200 calories and a protein intake of 1.2-1.5 grams per kilogram of body weight. Can be paired with intermittent fasting, such as 16:8 light fasting combined with resistance training. Weight loss should not exceed 1% of total body weight per week, and blood routine and liver and kidney function should be monitored regularly. Abnormal symptoms such as palpitations and edema should be immediately stopped and medical attention sought. The restoration of diet should gradually transition from liquid to semi liquid, with priority given to supplementing high-quality protein and multivitamins.
