Hunger and malnutrition can't be understood as individual problems because they involve social inequality, lack of public policies, and other economic factors.
Although malnutrition seems to be easy to describe, there are several explanations to define it. in brief, malnutrition is over-/under-intake or having an unhealthy diet pattern. nevertheless, weight change is the best indicator of malnutrition.
individual pathology is a definition that can not consider dependable to hunger. within clinical nutrition, someone who has malnutrition can not be capable to act in these forms of activities (weakness, high inflammation and low health level). the field of individual pathology is more related to social science and personality than the medical, and nutritional factors (or at least still there is no well-homogenized population to assess the effect).
In addition, there are situations where even in a high malnourished population the nutrition can not impact the individual pathology. for example regarding the effect of economics, marasmus and kwashiorkor Article Whole body protein kinetics in marasmus and kwashiorkor duri...
(two models of severe malnutrition) are the best options. within these populations, there is no change in the behaviour but families replace proteins (high-quality food) with carbohydrates (low Quality) that impact the entire metabolism of their children.
in addition, there is a chance that people with individual pathology behaviours because of their financial status be at higher risk of malnutrition (the cause of malnutrition is individual pathology) while you want to assess the opposite way.
I suggest the following guideline for understanding malnutrition better: Article Diagnostic criteria for malnutrition – An ESPEN Consensus Statement
Malnutrition includes over nutrition...obesity...as well as under nutrition. It can include specific nutrients and even lead to death of of the patient.
