It works. The question is whether or not people should use it.
Some people have legitimate reasons to use it, namely diabetics who need to lose weight but have a very challenging time with that due to their needs.
For most, though, they just need good 'ole fashioned self-control. I know this personally, as I'm in the process of cutting weight now. Chemical aids should always be a last-ditch remedy, because what people really need are a change in lifestyle.
