Did you know that tracking health activities can affect weight loss? We know this topic may be top of mind for many. That’s why our Achievement data scientists took a deep dive to explore a positive association between activity tracking frequency and weight loss.

To conduct the experiment, our team looked at behaviors within the Achievement Community. Specifically, the team found a positive association between activity tracking frequency and weight loss. Users who logged food with a relative frequency ended up losing an additional 0.63% of their body weight relative to low frequency loggers.

The team looked at secondary analysis as well which included examining the “adherent”/”non-adherent” period of tracking. In short, they wanted to see how the consistency with which one tracked activities impacted weight loss. Our in-house data scientists define “adherent recording period” as a time interval containing recordings with no gap longer than 4 days between consecutive recordings, with the first and last recordings in the interval separated from the rest of the sequence by gaps longer than 4 days. Non-adherent periods are the periods between adherent periods and have gap lengths that are always longer than 4 days.

The Results:

We found that adherent periods are associated with significantly higher weight loss than non-adherent periods across all activity types for the whole population, as well as for each gender analyzed separately.

On average, users lost an additional 2.74% of their body weight per month during adherent periods of weight tracking, 1.35% for food logging, and 0.60% for workout tracking.
