What is the author's style in The Fat Girl by Andre Dubus?

The point of view of "The Fat Girl" is the third-person omniscient perspective. This means that the narration relates what Louise, as well as some of the other characters, think and feel. The primary focus, however, is on Louise.

The story never explicitly expresses a great deal of Louise's inner life. The reader must infer much of why Louise takes certain actions, such as going on the diet or allowing herself to regain the weight. Though Louise's reflections are few, they are important, and they relate her overwhelming sense of loss of self. By the end of the story, the focus on Louise makes it clear that she believes she should be loved for herself, not for what she looks like.
