The Claim

The use of fitness and diet trackers is associated with higher levels of dietary restraint in observational studies, particularly when usage is driven by weight and shape concerns, but controlled experimental studies show inconsistent or null effects on dietary restraint behaviors following exposure to tracker use.

In plain English

People who use fitness and diet trackers tend to report stricter eating habits in surveys, especially if they are focused on weight or body shape, but when people are randomly assigned to use trackers in experiments, their eating habits do not consistently change.

See the scientific wording

Fitness and diet tracker use is associated with higher dietary restraint in observational studies, particularly when used for weight and shape concerns, but experimental studies show inconsistent or null effects on restraint behaviors after controlled exposure.

Why this might work

People who already focus on their weight and body shape are more likely to start using fitness and diet trackers. Using these tools reinforces their existing focus on food control, making their eating habits more rigid. The trackers themselves do not create this focus — they just become a tool for people who already have it.

  1. Study: Associations Between the Use of Fitness and Diet Tracking Technology and Disordered Eating Behaviour: A Systematic Review

    People who use fitness trackers often say they’re more careful about eating, but when scientists made people start using trackers in experiments, their eating habits didn’t get more restrictive — so the trackers aren’t causing the strict dieting; it’s more likely that people who already worry about weight are the ones who choose to use them.
