A grandmother – who weighed an astonishing 220kg (35 stone) and used to eat 4,000 calories a day – shed 127kg (20 stone) after she heard a nurse tell a colleague ‘If I ever get that fat, shoot me’.
Sue Callear (50) tipped the scales at 35 stone – her heaviest – and was classed as super-morbidly obese (meaning she could have died at any time).
Her body mass index (BMI) was a staggering 79 – almost four-and-a-half times the recommended 18.5 for a healthy adult.
