Most women would jump at the chance to put on some lipstick, sling on a pair of heels and head out for a romantic meal with their other half. But for super-sized mum Zeena Macdonald, 37, it was her worst nightmare. At 24 stone and a size 24, the home helper and mum-of-four was so ashamed of her appearance that she shunned date nights in favour of baggy sweatpants and a takeaway in front of the TV. When her husband tired of her excuses and ended their marriage in April 2011, Zeena decided to change her life for good and lost an incredible 13st. Now the former couch potato is a slinky size 10 and has never felt better.
