This Week's WHO: Lara Bingle's 12 KG Slimdown!

Crash dieting and body blow-outs are things of the past for the model and reality-TV star, who shows off her newly svelte figure in an exclusive bikini shoot and tells WHO how she has slimmed down from her heaviest weight of 63kg with the help of Pilates, smoothies and boyfriend Gareth Moody.

Having "got rid of everything that was weighing me down," Bingle, 25, says her boyfriend of 13 months has been the greatest influence on her new healthy outlook. "I've learnt you've got to be consistent in your eating and training. Gareth's taught me that."
