I'm going to shamelessly plug my book here. It's very hand-holdy and informational and much cheaper than a weight loss clinic.
Sometimes people do just need someone to tell them what to do because they're too weak to do it themselves, so they need someone to be their willpower for them. I'm not sure a clinic (or even my book) could help with that though, you kinda need like a drill sergeant constantly slapping food out of your hand if you're that way.
