A former male model and fitness instructor has gone from hunk to chunk in a bid to better understand his fat gym clients.
Paul 'PJ' James from Melbourne has piled on the pounds by cutting out exercise and sticking to a strict diet of chocolate, pizza, and beer.
The 32-year-old has already gone from 12 to 16 stone and says he will continue to gain weight until he reaches his 'ideal' target of a massive 20 stone.
At that point he plans to start exercising and dieting to prove to hefty gym-goers that weight loss is possible, he hopes he will be back down to his slender 12 stone frame by October ... but not as much as his girlfriend.
PJ says he had found it difficult to relate to overweight gym clients as he had never lived as a fat person.
But he is aware his calorific carbohydrate-heavy diet could cause problems and he is seeing a doctor weekly for check-ups.
He has already been warned his weight gain will increase the dangers of diabetes and high blood pressure.
