The Claim

Exercise motivated by appearance goals mediates the relationship between diet and fitness app use and disordered eating symptoms, with fitness apps reinforcing exercise behaviors driven by body dissatisfaction rather than health or enjoyment.

How it works
1 study reviewed
In plain English

People who use fitness apps and follow diets are more likely to exercise because they want to change their body shape, and this type of exercise is linked to disordered eating symptoms.

See the scientific wording

Exercise motivated by appearance goals (e.g., changing body shape) mediates the relationship between diet and fitness app use and disordered eating symptoms, suggesting that apps may reinforce exercise behaviors driven by body dissatisfaction rather than health or enjoyment.

Why this might work

When a person exercises to change how they look, their brain treats body dissatisfaction as a persistent threat, triggering stress hormones that heighten focus on appearance. This keeps the brain locked into rewarding behaviors that temporarily reduce distress, like tracking food or workouts, even when those behaviors become harmful.

  1. Study: Tracking every bite and step: Associations between diet and fitness app use, disordered eating, body image concern and compulsive exercise.

    Women who use diet and fitness apps to track calories or workouts are more likely to exercise because they want to change how they look, and this reason for exercising is tied to unhealthy eating habits. The study shows this link clearly.
