What are the hazards of long-term dieting for weight loss

Long term dieting for weight loss may lead to malnutrition, metabolic disorders, impaired gastrointestinal function, weakened immunity, and psychological problems. Extreme restriction of calorie intake can disrupt the physiological balance of the human body, and healthy weight loss should be achieved through a combination of scientific diet and exercise. Long term insufficient calorie intake can directly lead to a lack of essential nutrients such as protein, vitamins, minerals, etc. The accelerated breakdown of muscle tissue leads to a decrease in basal metabolic rate, which in turn increases the risk of obesity. Women may experience menstrual disorders or even amenorrhea, which is associated with abnormal estrogen levels. Some people may experience premature aging such as dry hair and loose skin, which is related to insufficient collagen synthesis.

Persistent hunger can trigger the body to enter a "hunger mode", where a decrease in thyroid hormone levels leads to a decrease in body temperature and a slower heart rate. Bile concentration can easily form gallstones, and continuous secretion of gastric acid may damage the gastric mucosa. Long term low carbohydrate diet may induce ketoacidosis, resulting in symptoms such as headache and nausea. Imbalance of gut microbiota can lead to constipation and absorption dysfunction.

It is recommended to adjust the diet structure gradually, with a daily calorie deficit controlled at 300-500 calories. Prioritize choosing high protein and high dietary fiber foods to enhance satiety, and combine resistance training to maintain muscle mass. Regularly monitor indicators such as body fat percentage and waist circumference. If discomfort symptoms such as dizziness and fatigue occur, seek medical attention promptly to assess nutritional status.
