People in Essex are fatter than the national average, with 16.7 percent of year 6 pupils in the county and 24.5 per cent of adults categorised as obese.
The statistics, published by Public Health England, come as Essex County Council calls for families to cut down on their sugar intake as part of new national Change4Life campaign, Sugar Swaps.
And the idea of eschewing sugary snacks and drinks is being backed by high-profile celebrity Jamie Oliver, who this week called for the UK to follow France's example and tax sugary drinks, suggesting that sugar should be taxed like tobacco due to the health problems it can cause.
More than 250 pre-schools, schools and colleges across Essex are already signed up to Change4Life, and work will take place throughout January to encourage primary school teachers to help pupils make healthier snacks, while Change4Life workshops will also take place at shopping centres across the country.
Cllr Anne Brown, Essex County Council's cabinet member for Communities and Healthy Living, said: "Unfortunately, too many of us are guilty of not paying close enough attention to the sugar content of our diets.
"Too much sugar can lead to high levels of stored fat, as well as problems such as heart disease, type 2 diabetes and tooth decay.
"By simply swapping your foods and drinks for no added sugar or sugar free alternatives you can make a huge difference to your family's health.
"The council is working very hard to improve the health of Essex residents and wholeheartedly supports this campaign."
