Quit Smoking? Save money? Spend more time with family?

The above are all popular amongst resolution-makers, no doubt, but you’d be hard-pressed to find many more that aren’t fitness- or weight-loss-related. You can chalk that up to whatever you want — the way we gorge ourselves over the holidays, the perception of a new year and a fresh mindset — but the fact remains: fitness sells in January. (Seriously, go to your local gym this week and ask what their sign-ups have been like.)

That phenomenon translates to eBay, too. While we’ve spent much of the past couple months showing you category trends that rise and fall with the holiday months of November and December, check out some of these two-year total sales trends in eBay’s Weight Management category.

Now, you may not be able to tell from these blurry screen-caps, but all three of those trend lines correlate pretty tidily with the first week of January!

As for those other resolutions, a quick search for “quit smoking” in Terapeak’s Category section tells us there’s an eBay sub-category under Health & Fitness titled Smoking Cessation, with further sub-cats like Patches, Gum/Lozenges, and Alternate Therapies. Here’s a total sold listings trend for the latter:

So there’s that, too!

Good luck everyone with your own!
