The 2012 season of The Biggest Loser Australia is due to kick off on the 23rd of January. This year we’re back to single contestants, rather than families or couples. They’re also single in the sense of not having a significant other in their life, which will presumably be attributed to their weight even if their singledom is actually related more to them being jerkfaces.

In another twist to the formula this year they’re not just having a battle of the sexes but a battle of the age groups. Tiffiny’s returning to lead the white team and this year it’ll be a group of 4 women all under the age of 30. Michelle’s back too, of course, and her red team will also be all women except over the age of 30. Shannan’s getting a group of under 30 men in blue and The Commando will be taking on the group of over 30s men in black.

This puts Shannan and Commando in the early lead since the men always tend towards losing a lot more weight at the start of the show. But when those initial easy kilograms have fallen off will the men be able to keep ahead of the women?

Another teaser trailer has also appeared on the official site, you can check it out by clicking here. This one has the under-30 James, the over-30 Brenda and the over-30 Alex. It may have been up for a while. If it has, shut up. :)

James looks a little bit like Season 3 Loser Sam – Or is that just me? In any event he doesn’t really look all that big, which doesn’t bode well for his chances, but should mean he’ll come out the other end a lot healthier and happier, which is always nice.

Brenda looks like somebody’s Mum. But that would mean she’d found love at some point. So she couldn’t be on the show. RIGHT?

And Alex is huge! Like, properly rounded. But is 50 too old to handle the rigours of Commando-style training? It worked for Bob, so Alex could be one to watch.

We’re down to four nights a week this year. Monday, Tuesday, Wednesday and Thursday between 7pm and 8pm.

Are we excited yet?
