In episode one, Gok meets 29 year-old midwife Liz Marlowe, a working mum-of-two whose curvy size 16 figure is sending her self-esteem plummeting to rock-bottom. A former head-turner who never struggled to capture male attention, Liz now can't even bear stripping off in front of her adoring husband Adrian.

When they first met eleven years ago she was the leggy blonde in her group of friends, but two kids and a few dress sizes down the line she's feeling fat, frumpy and at an all-time low.

Desperate to boost her self-confidence, Adrian constantly tries to reassure her that she's still the same "fantastically beautiful, stunning gorgeous lady" he fell for in the first place, but with Liz hiding her body under layers of unflatteringly baggy clothing, it’s clear that his efforts are falling on deaf ears. So shy that she hasn't been near a full-length mirror in nearly 18 months, Liz has become a walking testament to the fact that blondes don't always have more fun.
