I assume there is more to it than that. MS Money's debt planner started with you creating a budget. From there it knows about how much extra you have each month. It then takes in how much debt you have and their interest rates, and from there it plots out how much to pay each debt every month. It's encouraging because you can see the graph converging towards zero, and it also indicates how much you'll save in interest charges versus just paying the minimum (which for a lot of people is probably quite a bit). MS Money is the sole tool that got me out of a lot of debt, and it conditioned me to be responsible with my money ever since.
As for weight loss, there pretty much are sites like that. fitday.com, livestrong.com, etc. None of them are magic pills, just like ready for zero won't be. All sites like this require a user who is determined and willing to make the change. But these sites can help the person who really is looking to make that change and increase their chance at success.
