US student, 26, who drank 5.5 LITRES of fizzy drink a day loses 280lbs with the help of a gastric bypass surgery after discovering she was pre-diabetic at just 24 
Student Erika Olson, 26, from Clearfield in Utah, weighed 420lbs at her heaviest after gorging on a diet of fast food and pastries, all washed down with sugary soda. But, after undergoing a gastric bypass, Erika now tips the scales at a svelte 147lbs and finally has the body and healthy lifestyle she has always wanted. She is pictured left and centre before the weight loss and right after.

The world's fattest child Arya Permana is now unrecognisable (left) after the schoolboy managed to shed more than half of his body weight. Arya Permana, 14, who weighed an eye-watering 30 stone aged just 11 (top right, bottom right), now weighs an impressive 13 stone and is encouraging others to follow a healthy diet. The school pupil had baffled doctors five years ago when they saw pictures of him as a morbidly obese child playing in a water tank to cool his body in the small village of Cipurwasari in West Java province in Indonesia. Arya was so large that no clothes would fit him - he was only able to wrap a sarong around his body.
