Does malnutrition lead to weight gain

malnutrition may lead to weight gain, but not all malnutrition causes weight gain. Malnutrition is usually divided into two types: undernutrition and overnutrition. Undernutrition may lead to weight loss, while overnutrition may lead to weight gain. Malnutrition is usually caused by long-term calorie intake or nutritional imbalance, in which the body burns stored fat and muscle to maintain basic physiological functions, leading to weight loss. Commonly found in impoverished areas or populations with extremely restricted diets. Nutritional deficiencies may lead to weakened immunity, anemia, delayed growth and development, but generally do not directly cause weight gain. Malnutrition caused by overnutrition may lead to weight gain. This situation usually occurs when consuming too much high calorie, low nutrient value food, such as refined sugar, saturated fat, etc. Although the calorie intake is sufficient, essential nutrients such as vitamins and minerals are lacking. Long term exposure may lead to metabolic disorders, fat accumulation, and ultimately obesity. This type of malnutrition is quite common in modern society, especially among people with an unreasonable diet structure. Maintaining a balanced diet is important for preventing malnutrition and obesity. It is recommended to consume a moderate amount of high-quality protein, whole grains, fresh vegetables and fruits, and other nutrient rich foods every day, while limiting the intake of high sugar and high-fat foods. Maintaining regular exercise habits can help maintain a healthy weight and good nutritional status. If there is an unexplained weight change, timely medical examination should be sought to rule out potential health problems.
