Ulu Tuʻipulotu, 26, who is of Tongan descent and weighs 337kg, is said to be Australia’s heaviest man.

In a desperate bid to save his life Mr Tuʻipulotu has vowed to slim down by losing 15 kilos over a period of one month.

He suffered with weight problems and his doctors have warned that he will die if he cannot lose weight, according to the Daily Mail.

Tuʻipulotu has attempted diets, such as Lite ‘N’ Easy packaged food plans. He’s tried Optifast, a milkshake weight loss plan, as well as going to the gym but nothing has worked so far, the paper says

He is living with his Tongan family in Quaker’s Hill and he has gone public with his weight loss struggle after signing up to a two-year sponsored psychological and physiological program ran by a Sydney hypnotherapist.
