Ross Walker said obesity levels had reached crisis point in Australia, with 70 per cent of men and 50 per cent of women overweight or obese. 

He said the campaign would help educate the public on obesity and teach them how to lead a healthy lifestyle. 

"I think (LiveLighter) is fantastic," he said. 

"The more people who can be educated on health the better."

Dr Walker said there were five key principals to being healthy and, if done correctly, could reduce a person's risk of all diseases by 60 to 70 per cent. 

"Number one is you can't be healthy if you smoke, drink too much alcohol or do illegal drugs," he said. 

"Number two, (people need) seven to eight hours of good, quality sleep every night. 

"Number three, (people need to) eat less food and more natural food.

"Number four, (people need to do) three to five hours a week of some form of exercise.

"Number five, happiness. The happier you are the more content you are with your life, you get on with the people around you, the more you have that sense of inner peace the less disease you have."

City of Greater Bendigo and Bendigo Community Health Services have partnered to deliver the campaign throughout the region, which launched on Wednesday. 

The campaign includes print, television and radio advertisements. 

The advertisements are a copy of a campaign which started in Western Australia two years ago. 

Dr Walker, who was a guest speaker at the launch, said "education was vital".

"The smoking rates in Australia are now down to 13.8 per cent from 20 to 25 per cent," he said. 

"Why, because smokers are made to feel socially unacceptable.

"If we encourage people to not eat as much food, to go out and move, the obesity rate will drop too."
