By not eating. Anorexia is when you've starved yourself to become underweight. If you're a fat person that simply wants to become thinner, then you exercise, eat more fruits and vegetables, and drink water. That's what a mother-hen would say....

The exact opposite happens
It seldom is ever just one person who makes a mean comment about weight that forces someone to become anorexic. Often, it takes many comments of some period of time for the person to begin to develop their anorexic tendencies. Usually it is coupled with low self esteem and low body image.
Before a person become anorexic, they are just like any other normal person in the world.

There is no real "average" fat intake of an anorexic individual, as each person consumes different amounts of food, calories, fat, carbohydrates, ect. each day. The only real similatrity is that anorexics will often have a fat intake that is drastically lower than what is considered "healthy".
An Anorexic person suffering from a is a psychological disorder called anorexia, which makes someone believe they will become fat if they eat. The disorder leads people to starve themselves putting their health in danger.
An anorexic is a person who suffers from anorexia.
