How can someone be fit and malnourished?

Someone can be fit and malnourished if they engage in regular exercise and maintain a healthy body weight, but their diet lacks essential nutrients. This can happen if they consume a high-calorie diet that is low in vitamins, minerals, and other important nutrients, leading to deficiencies. Additionally, certain dietary patterns, such as excessive reliance on processed foods or restrictive diets, can contribute to malnutrition despite a fit appearance. Thus, physical fitness does not always equate to proper nutrition.
