Gym trainer gets fat to help clients

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.
