I'm sure it works, if you do it right.  They don't seem to understand that too many calories = you're gonna stay fat if you don't burn them.  One woman today posted her dinner as a great "low carb meal".   A pound of burger, hollowed out and filled with cheese, wrapped in bacon, more cheese, and baked.  Oh and there were a couple of tomatoes in there, so I guess it counts as a salad.  That's over 1000 calories in the burger alone.  And you know she didn't work it off.The page is full of posts like that, it's amazing.
