I remember seeing Big Wal in the first biggest loser series drop 15kgs between weigh ins.
Yep. But his weigh-in was over 2 weeks, not one.
There's allot of loop-holes with TBL series.
1 week on the ranch = 2 weeks "real time"
They don the T-shirts about half way through the show to not show the loose skin from tons of muscle loss.
30% of their "weight loss" is muscle loss. On average according to the TBL Doctor.
They de-hydrate themselves b4 weigh-ins, go low sodium, and wear heaps of clothes while they workout (not on TV) and close the gym windows to loose more water weight.
They use clear-tape and makeup at Finale, to disguise any loose skin.
Wal used to email me, and informed me he packed all the weight back on and told me I was an inspiration to him - as I did it without a TV show or trainers or gastic band etcs, I was amazed how humble the guy was. A real class act.
Harry should be the real winner of TBL series one, not Adro, as they brought Adro back after he was eliminated (and he didn't earn his way back into the show) he blackmailed them somehow, Ajay Rochester knows the real story behind this.
