Well this is weird

I’m not entirely sure how Fitbit calculates steps. You put in your height and your weight in the dashboard, and pick the hand you’re wearing the Fitbit on (dominant or non-dominant hand).

The reason I bring this up is I’ve noticed a difference between the results from my old Fitbit and my new one. It might be that they’re just slightly different in how they read steps.

I also wondered if weight is part of the calculation, maybe more than I realized. When I got my first Fitbit, I picked a likely number for my weight (I don’t weigh myself, since knowing the actual pounds I weigh tends to trigger my eating disorder—no thanks on that!).

Last month, right before a medical test that required sedation, the person gathering my health information told me what I weigh (I’ve been doing my best to forget ever since). So I put that weight in the dashboard for my Fitbit when I set it up.

Normally on non-run days, I’ll get between 5 and 6 thousand steps just going about my normal day. Now I get in the high 4 thousands. Runs are clocking in slightly less also, but my running route hasn’t changed.

In a way, I don’t care—I use the Fitbit as a relative scale that I’m staying active (and I rely on the silent alarm every work day, love that gentle buzz). But I do find it kind of strange that weight—if that’s the reason—changes my step count so much.
