Heart disease and Type II diabetes are more likely to affect obese people, say health chiefs, and the expanding waistlines in Widnes and Runcorn could see the area become a hotspot for these conditions.

Fiona Johnstone, acting director of public health in Halton, said: "It is something we've realised for a long time. It's not something that has surprised us."

Halton came 20th in a table of 434 towns across the UK whose residents were most at risk of obesity and was second in the north west, beaten only by Knowsley.

The study, by Experian and Dr Foster Intelligence, combined data on body mass index (BMI) with a recent BRMB health survey and postcode analysis to show which types of people have high and low body weight and where they live.

The junk food-filled diet and lack of exercise in Halton is a major concern for the Primary Care Trust, which is carrying out a wide range of schemes to promote healthier lifestyles.

"We've developed a physical development strategy and an obesity strategy for both adults and children," Fiona said.

"It's about being active, setting yourself goals to get more active and being sensible about what you eat."

Halton Council has also introduced a number of schemes to promote healthier lifestyles including exercise initiatives and healthy eating.

A council spokesman said: "The five-a-day message has been heavily promoted across Halton, and 53 'Cook and Eat' sessions took place to encourage people to try new ways of eating healthily."
