Video-Super-slimmer lost staggering 18 stone - more than weight of average professional rugby player

The 45 year-old became a recluse as she soared to 31 stone and was left too embarrassed to leave her home.

She tried gastric surgery but that failed and she continued to pile on the pounds. But in the past five years she has lost almost two-thirds of her bodyweight and now tips the scales at under 13 stones. And in doing so she has found a new lease of life and started doing things she could only dream of - like riding a motorbike.
