Earlier this month I mentioned Jackie O's 'fat bet'. Australia's leading lady of the airwaves had been challenged on air: lose 4 kilos and Kyle Sandilands would donate $5K to her favourite charity, Animals Australia (or, don't – and the money goes to a factory farm!).

An absurd bet, you might think (particularly when we all knew Jackie was perfectly proportioned already! Sheesh!!) But absurdities aside, Jackie knuckled down for the animals' sake, worked hard, and held Kyle to his word… And the result? Well it was a verrrry close call, but I'm glad to report that despite being 200g short of her target weight, Kyle saw the light and wrote out one big phat cheque to Animals Australia – that will be used to expose the cruelty of factory farming!

How did Jackie lose the weight? It's no secret that it's easy to shed excess weight on a healthy vegetarian diet – and that's exactly what she did!

Whilst Australia wrestles with the dubious title of "world's fattest nation", we salute Kyle for inspiring us all to fight our collective waste-line. But next time Kyle, perhaps you might like to challenge yourself to lose 4 kilos (or maybe 10?). We could run a new ad campaign about the link between obesity and the consumption of animal products with the proceeds ;-)

If you're a 2DayFM listener you're probably aware by now of Kyle's "fat challenge". But if you're not, the self-admittedly rotund co-host of the Kyle and Jackie O show has accused the ever-gorgeous Jackie of being fat! (Yes, it's a topsy turvy world we live in).

It seems that Kyle is so concerned about Jackie's health and belt size that he's issued his vegetarian co-host a challenge: lose 4 Kg and he'll donate $5,000 to her favourite charity: Animals Australia! And if she fails...? Kyle says he'll give the $5,000 to a pig factory farm -- Jackie's worst nightmare!

Now, I don't know where this mic-slinging diva will even find 4 Kg to lose... but if anyone can do it for the pigs, I'm willing to bet that Jackie O can.

The outspoken radio personality and former Big Brother host has already shown her commitment to helping animals by not eating them. She also posted information on her website to inform listeners about the miserable lives of animals trapped in factory farms in Australia. Go Jackie!

Who do you think will win the fat challenge? You can have your say and pass on your encouragement to Jackie on the 2day fm website. :-)
