Researchers using artificial intelligence analyzed nearly 60,000 social media posts to uncover unexpected harms linked to popular fitness apps.
Published in the British Journal of Health Psychology, the study examined top-grossing apps like MyFitnessPal, Strava, WW, Workouts, and FitCoach.
Although these apps aim to encourage healthy habits, an emphasis on numbers and metrics can leave users feeling discouraged, ashamed, or disconnected from real wellness.
The team suggests developing apps grounded in psychology that prioritize emotional health and intrinsic motivation rather than strict numerical targets or profit goals.
Paulina Bondaronek, PhD, from University College London, noted that while fitness apps remain highly profitable and widely used, their negative impacts are often overlooked.
She explained that reducing health to steps or calorie counts can demotivate users and diminish their connection to long-term wellbeing.
Digital health platforms offer unique opportunities for self-monitoring, remote interventions, and behavioral changes.
To assess possible downsides, Bondaronek’s team combined AI-driven topic modeling with human qualitative analysis on 58,881 social media posts about the top five fitness apps.
The Machine-Assisted Topic Analysis (MATA) approach allowed the study of massive text datasets that are typically unmanageable for traditional qualitative research.
Examining 13,799 negative posts, the researchers identified patterns showing that tracking calories, setting rigid goals, and emphasizing metrics often caused frustration, guilt, and demotivation.
Some users struggled to meet numeric targets and expressed anxiety about food choices or physical activity, highlighting limitations in app algorithms that overlook personal differences or real-life complexities.
Technical issues, such as syncing failures or lost workout data, triggered stress and distrust, leaving users frustrated with inconsistent results.
Notifications or reminders sometimes provoked guilt or irritation, prompting over-exercising or app abandonment to compensate for missed streaks.
Users also debated the apps’ broader societal role, often framing health as a personal responsibility and downplaying apps’ potential contributions to negative outcomes.
The study concluded that commercial fitness apps need better evaluation and psychologically informed, user-focused designs prioritizing wellbeing and intrinsic motivation over rigid metrics or profit.
