I once paid for a membership on a weight loss web site, but it was only $20 a year, and I only renewed because I liked the people and didn't want to lose access to the forums.

Since they raised their price years ago, I've lost weight counting calories this time, which has been free (other than buying a decent food scale).
I've lost weight while going to the gym and while not going to the gym. Most of the time when I didn't have a gym membership, I used exercise videos and dumbbells, so I guess I spent SOME money, but less than your average gym membership for sure. I'm only willing to pay for the gym now (and mine is CHEAP) because I'm in love with the elliptical, lol.
Now, I've seen people doing stuff at the gym that doesn't require any gym equipment. Stuff you could do in a tiny dorm room (it's a college gym). But I think for some people, the fact that they paid money means they'll actually stick with their program, because otherwise they feel guilty for wasting it. I've never been that type - if I can get something for free, there's no way in heck I'm paying for it, and that includes things like motivation and commitment.
