NED Mannoun's fitness campaign isn't just about getting into a smaller suit size. It could save his son's life.
The Liverpool mayor has lost 11 kilograms since he started his healthy eating and exercise crusade on his 32nd birthday this year, on January 15.
Cr Mannoun's motivation was to be healthy enough to donate one of his kidneys to his son Solomon, 2½, who was born with one kidney.
"I wanted to be healthier overall but Solomon has been my motivation," he said.
Solomon suffers kidney failure, has cysts on his kidney and must undergo dialysis.
The family had to wait until Solomon weighed 10 kilograms so the transplant could take place.
"Now we've got to that point so the operations will be happening in September."
He said he hopes he can also be an inspiration to other Liverpool residents.
"Liverpool has the highest rate of diabetes in the state and after roads, footpaths and safety, encouraging residents to be fit is one of our top priorities as a council.
"That's why we we're focused on providing good parks, recreational places and outdoor gyms for people to go for a walk and enjoy family time getting fit together."
He said one of the highlights of the process has been losing 15 centimetres off his chest and losing his "man boobs".
But he said he would not have achieved what he had without the guidance of his fitness instructor, CrossFit Chipping Norton director Scott Dillon.
"He's been guiding me and keeping me on the right track throughout the whole process, giving me an eating plan as well as a fitness regimen."
Mr Dillon said his program was all about creating a tailored approach for each client.
"We work with each person to work out what their lifestyle is like and where their personal fitness level is at and create a program for them," he said.
"Then we work with them to meet their goals at a slow and manageable pace.
"This leads to successes every day and keeps up the levels of their motivation."
