Change Google Account Linked to

I’d like to set up to pull in my Google Fit information. I have two Google accounts, one that’s associated with with Beeminder and another that I use for Google Fit.
When I link to Beeminder, and connect Google Fit, it’s pulling data from the wrong Google account. This may be because of me originally setting it up incorrectly, but I can’t figure out a way to change this.
Anyone know how to fix this?
