Answer:
Eating disorders that can cause malnutrition are most commonly anorexia and bulimia. In both, the body is not gaining the essential nutrients (vitamins, minerals, calories, fats, ect.) that it needs because the individual is not eating enough food (anorexia) or is purging / vomiting the food back up (bulimia), so the body does not get enough of what it needs daily. As a result, it must rely on stores of nutrients and calories (energy) from fat and mucle cells. This will soon run out, and the body becomes malnourished.
