How does overeating lead to malnutrition?

Overeating can lead to malnutrition when an individual consumes excessive amounts of calorie-dense but nutrient-poor foods, which may lack essential vitamins, minerals, and other nutrients. This can result in an imbalance where the body receives enough energy but insufficient nutrients to support its functions. Over time, this can lead to deficiencies that impair health, even in the presence of excess body weight. Essentially, overeating can mask malnutrition by providing calories while neglecting nutritional quality.
