A super-slimmer lost an incredible 19st in just 18 months after his wife joked he looked like Jabba the Hutt from Star Wars.
The former lorry driver piled on the pounds munching on fry ups, fish and chips, crisps, curries and Chinese takeaways.
But the 55-year-old revealed that it was a picture of him balancing a tiny-looking laptop on his enormous stomach that made him realise he needed to change his ways.
But he refused, and determined to lose the weight himself, he visited Slimming World with his friend Penny in January 2012.
Following the new eating plan, Mr Oates ditched the crisps and fried food, and began cooking from scratch.
He swapped the stodgy dinners and fatty fry ups for fruit and stuck religiously to healthy Slimming World recipes.
