What is it with Supersize vs Superskinny (Channel 4, Tuesday, 3 March, 8pm)? I mean, I've no idea what it's trying to tell us. Of course, I recognise that it's doing a good thing by saying 'Look, we've all been banging on about fatties for ages, but really skinny people aren't cool either, y'know?'... but honestly, I'm not sure I learn a damn thing when I watch the show. The clue hangs on the word 'too'. Too fat? Bad. Too skinny. Also bad. So how do they manage to drag it out for an hour?

If anything, the most important 'too' concerning this show is that it's got way too much padding. Seriously. The premise of the show is this: Fat person is told to eat less, and healthily and thin person is told to eat more, and healthily. In between, we'll go and watch a women talk to a bunch of people about their diets. And how they're all eating more healthily.

That's pretty much it.

However, somehow, Dr Christian Jessen and Anna Richardson show us this like it's real news. It's weird. Are we as a nation so slackjaw stupid that we need someone to repeat this mantra reeealllly slooooowly over a series of weeks until we get it?

Last night's little 'n' large were an ex-jockey who looked like a cross between Premiership footballer Andy O'Brien and that skeletal thing that vomits out of the telly in Aphex Twin's 'Come To Daddy' video, and a man who seems to do nothing more than eat shed loads of food and quaff staggering amounts of lager.

To prove some kind of point, these people swap diets. Why this happens is still something I've not worked out as, early doors, with the aid of a tube full of food, fags and beer, we've already been told that both of them have horrendous diets. All we do is swap one bad thing for another. It's little wonder that the little jockey fella did nothing but whine about it all... and boy, did he whine.

Elsewhere, Anna Richardson went all the way to LA to see how silly women are, as they desperately try to lose weight the minute they give birth. As if we needed telling that LA was the weirdest place on Earth?! Basically, this show is a reasonable watch, with a few moments that kid you into feeling like it's useful, but for the most part, it's complete trash with blindingly obvious advice.
