That Gillian McKeith is couring controversy again. After being forced to drop her spurious “Doctor” title and being subjected to endless reams of vitriol from our resident McKeithophobe, she still won’t lie down.

Now she’s being lined up to present the new Channel 4 diet show Supersize Versus Superskinny, in which very very fat people will swap diets with very very thin people, presumably to see if we end up with twice as many very very average people. As if.

Naturally, this is all dressed up is some pseudo-scientific twaddle about “examining the effect of dramatic changes in diet,” when we all know it’s being done so C4′s audience can laugh at the antics of the fat and thin people as they try to come to terms with eating in a way they don’t normally. That is, starving themselves and stuffing themselves, respectively.

So not content with several years yelling at people for eating the wrong stuff, followed by yelling at them and forcing them to eat disgusting stuff in an effort to put them off food altogether, now the Food Nazi is going to yell at them for eating the wrong amounts, the wrong way.

Conscious of previous negative publicity surrounding “the Doctor,” C4 have lined up a real doctor to supervise filming, but this hasn’t stopped medical advisers like Dr Ian Campbell from Weight Concern expressing serious doubts about the programme’s approach. “For the sake of entertaining people, this will replace one person’s bad diet with another’s bad diet,” he said.

He was almost right. I just don’t know about the “entertaining” part.
