Once 180kg 'Amanda' (now about 50kg less - but still a Momma) sang at the finale, it's because big people get powerful lungs (it's been hard to breath) and so they can do opera tunes.
The largest collection of loose skin went to the winner of the evening 'Bob' who lost over half his body weight. While usually this loss would kill a human, in Bob's case it's made him $200,000 richer so he can very luckily pay for a talented local seamstress to guide a sewing machine along the edge of his entire skeleton - then slice of the weighty excess.
I personally was upset Tiffany didn't win, it continually sucks when the chicks can loose as much butter as the dicks. But I will sleep fine tonight because Bob was her stepdad - this is good not because she might need to have the largest organ on her human body (skin) tailored (because she's younger that somehow means theres elastics in her skin so it'll bounce back) but because Bobs an oldie and that money should find its was to Tiff in the next decade, - less if Bob can't retain his healthy-yet-gaunt new figure and magnetically finds himself the largest patron KFC has ever fed.
