Until two years ago it was almost impossible to tell identical twins Stacey Warren and Kelly Acres (40) apart, but now they couldn't look more different.
Struggling with their weight since they were children, Stacey and Kelly both found themselves tipping the scales at over 20 stone. In 2010 Stacey decided to take the drastic step of going under the knife and having a gastric band fitted. Stacey has shed more than half her body weight and, at just 8 stone 8lbs, has an enviable size 8 figure.
Kelly is now desperate to have the surgery that has transformed her sister's life and they join us to reveal how Stacey's dramatic weight loss has impacted on their relationship.
