New figures from Public Health England show two-thirds of adults in Calderdale are overweight or obese.
Calderdale’s 66.3 per cent is above the national average of 63.8 per cent, but Doncaster has the highest figure in Yorkshire of 74.4 per cent.
Health problems associated with being overweight or obese cost the NHS more than £5 billion each year.
Calderdale Council’s Director of Public Health, Paul Butcher, said: “We know there is a national problem with obesity and unfortunately Calderdale is no exception.
“There are many actions that need to be taken to tackle this issue. Food manufacturers could encourage healthier food purchasing by offering discounts and we can ensure the environment we live in encourages walking and cycling.
“The schemes we offer provide different ways people can lose weight through Slimming World, Weight Watchers and Upbeat.
“We are offering free 12 week vouchers for weight loss which can include use of the Council’s leisure facilities or free weight management sessions at your local GP practice.”
Dr Steven Cleasby, NHS Calderdale Clinical Commissioning Group (CCG) said: “While the figures are a concern, we are working with the local council and partners to help people improve their lifestyles.
“One initiative is the Food for Life Partnership across schools to create a network of schools and communities to transform food culture.”
