Malnutrition primarily stems from poor dietary practices, which encompass a lack of balanced nutrition necessary for the body to function optimally. This can involve insufficient intake of essential nutrients, such as vitamins, minerals, proteins, carbohydrates, and fats, or the excessive consumption of unhealthy foods. When individuals do not adhere to guidelines for a healthy diet, their bodies may not receive the necessary nutrients to sustain health, leading to various health issues, including stunted growth, weakened immune systems, and organ dysfunction.

While excessive calorie intake can lead to overweight or obesity, it does not directly address the broader aspect of malnutrition, which includes both under-nutrition and over-nutrition. Genetic factors can influence an individual's susceptibility to certain conditions, but they do not primarily cause malnutrition on their own. Lack of physical activity is often a contributing factor to overall health but is not a direct cause of malnutrition, as malnutrition itself is rooted in dietary choices rather than levels of physical activity.
