Shirin Arabpour tipped the scales at a whopping 22st (139.7kg) and could barely fit into a size 24 dress after years of piling on the pounds. The 29-year-old was left with severe health issues after regularly gorging on an unhealthy diet of fast food and takeaways. But the lardy mum-of-one decided to get fit and shed the flab in January 2012 after doctors told her she was severely overweight and at risk of deadly gallstones forming in her gallbladder. And, determined to become a top fashion model, Shirin battled the bulged. She drastically changed her lifestyle and diet and even dumped her partner of seven years in a bid to become a model. Shirin, who works in a watch shop, swapped the pizzas and fatty foods for fresh meals cooked herself with fruit and vegetables and began a fitness routine.
