Sharon Smith pictured before (L) and after (R) weight loss. A super-slimmer told yesterday (Mon) how she was shamed into losing over ten stone after she was forced to stand up for an entire 11 HOUR plane flight. See NTI story NTISLIM. Sharon Smith, 43, tipped the scales at over 20 stone and was a bulky size 26 when she went on the embarrassing business trip in December 2012. The designer struggled to fit into the tight plane seats so ended up standing for the flight to Hong Kong because she felt sorry for the passenger next to her. Sharon decided to lose weight at the start of last year after getting fed up of squeezing into train seats on her regular commutes to London for work. She quit her high-flying job as a children's clothes designer in January 2014 and went freelance which meant she could work at home and go for regular walks at lunchtime. Incredibly, after taking up running in March last year Sharon shed a staggering ten stone and now weighs a healthy 9st 9lbs.
