Jody Harbert is a diet and nutrition expert who travels around the state to speak in middle and high schools.(22)She primarily speaks to students in health classes, but sometimes the school will arrange for her to speak to several different groups of girls.(23)Her biggest concern is the emphasis American culture places on thinness and the negative ways this affects girls today. Jody has a Ph. D. in nutrition, but more important, she has personal experience. Her mother talked her to diet when she was only eight years old.

She describes how the definition of beauty has changed over the years and even from culture to culture. She then talks about health issues and the physical damage that can occur as a result of dieting. Finally, she addresses self-respect and the notion that a person’s sense of beauty must include more than how much a person weighs.(25)Sometimes, Jody feels that she succeeds in persuading some students to stop dieting. Other times, she feels that she fails.
