Can drinking water without eating for seven days to lose weight in fasting

Drinking water and not eating for seven days may lead to weight loss in the short term, but the weight loss effect is mainly due to water and muscle loss, and there are health risks involved. Extreme dieting may lead to hypoglycemia, electrolyte imbalance, gastrointestinal dysfunction, etc., with a higher probability of rebound. During fasting, completely cutting off food intake will prioritize the consumption of liver glycogen and muscle glycogen reserves, followed by the breakdown of muscle protein for energy supply, resulting in a decrease in fat metabolism efficiency. Due to a lack of electrolytes such as sodium and potassium, symptoms such as dizziness, fatigue, and arrhythmia may occur. Long term hunger can trigger the body's self-protection mechanism, causing a decrease in basal metabolic rate, and making it easy to quickly regain weight after returning to a normal diet. Some people who try short-term fasting may experience a false weight loss due to water loss, but it is accompanied by problems such as decreased muscle mass and skin sagging. Such extreme dieting is strictly prohibited for diabetes patients, pregnant women and other special groups, which may lead to ketoacidosis or abnormal fetal development. There have been cases of gastric mucosal atrophy and liver dysfunction caused by long-term fasting in clinical practice. Scientific weight loss should follow the principle of gradual progress, and it is recommended to control the daily calorie deficit within a reasonable range, and achieve fat consumption through a balanced diet and moderate exercise. It can increase the intake of vegetables, high-quality protein, and whole grains, avoid high sugar and high-fat foods, and engage in aerobic and resistance training every week. If you need professional weight loss guidance, you should consult a nutritionist to develop a personalized plan and not blindly try extreme dieting methods.
