I saw that clip of Corden's too and thought he did a good job of answering Maher. The research shows, and we all know it - fat shaming doesn't help, it only compounds the problem. Inevitably though someone will come along and unhelpfully say, "Well, it was only when I woke up to how many pounds I had packed on - when I faced what a fat slob I had become - that I lose the weight by just putting down the fork."

It sounded like Corden got a warm reception by his audience. But then Maher did too, of course.
