The Claim
Use of fitness and diet trackers is associated with higher levels of disordered muscle-oriented behavior in observational studies, particularly among individuals motivated by weight and shape concerns.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who use fitness and diet trackers show higher levels of disordered behaviors focused on muscle building, especially if their main motivation is changing their weight or shape.
See the scientific wording
Fitness and diet tracker use is associated with higher disordered muscle-oriented behavior in observational studies, particularly among users motivated by weight and shape concerns, but no experimental studies have examined this relationship.
Constantly checking body metrics like weight and muscle size keeps the brain focused on physical appearance, which strengthens neural pathways that link self-worth to muscular appearance, leading to compulsive behaviors around training and diet.
What the research says
1 studyPeople who use fitness trackers and care a lot about their body shape tend to show unhealthy muscle-building habits, and this link has been seen in many surveys—but no experiment has proven that the trackers themselves cause these habits.
