This is actually a setting you choose when you set up your tracker. This allows users to share their stats with others on MedHelp even if they don't want to share all the details of their tracker. So when you set up the tracker, there was a check box that says, "Add my Weight Tracker Stats to my Profile page" and if checked, this automatically adds the stats to your profile page. To remove it from your profile page is very simple. Go to your profile page and click the "x" in the upper right corner on the widget. That should remove it.
Thanks,

I've done that. The scale ticker is not showing up on my home page, but my weight statistics still show up there. That's what I'm trying to get rid of.
Select trackers so you see your weight tracker (like you are about to edit it). Look towards the bottom of the page, and you'll see your weight summary -- called a ticker. Below is a link that says "Embed and configure ticker." Click there and you'll find the check boxes that turns off public display of the summary.
