Bulimia primarily involves which of the following behaviors?

Bulimia is characterized by a specific cycle of behaviors that includes episodes of binge eating followed by compensatory actions to prevent weight gain, such as purging. This behavior reflects a psychological struggle with food, body image, and self-control.

In bulimia, individuals typically consume large quantities of food in a short period, which can lead to feelings of loss of control. The subsequent purging can take the form of vomiting, excessive use of laxatives, fasting, or excessive exercise, as a way to counteract the effects of the binge eating.

The other behaviors listed, such as routine physical exercise, excessive fasting, and consistent meal planning without binge eating, do not align with the nature of bulimia. While these behaviors may relate to other eating disorders or issues with food, they do not encompass the crucial component of bulimia, which is the cycle of bingeing and purging. Therefore, the correct understanding of bulimia identifies binge eating followed by purging as its defining characteristic.
