When should a person be called a malnourished person?

A person is considered malnourished when their diet lacks essential nutrients or when they consume an inadequate amount of calories to meet their body's needs. This can manifest as undernutrition, characterized by underweight or wasting, or overnutrition, leading to obesity and related health issues. Malnutrition can result from various factors, including food scarcity, poor dietary choices, or underlying health conditions affecting nutrient absorption. It's essential to assess both dietary intake and overall health to determine malnutrition accurately.
