Around one in 10 UK children in Reception and a fifth of UK infants leaving primary school are obese.
A Royal Society for Public Health( RSPH) report said healthy eating vouchers and after-school activities could be the answer.
But other people who work with parents of overweight children say different measures work better.
So what can be done to help prevent or reduce child obesity?
The government’s main approach to tackling child obesity is through advice schemes like Change4Life, put up in 2009.
It offer advice and tips-off for families to encourage lifestyle changes – including recipes and activity ideas.
A government spokesman told since Change4Life was started, more than 2.7 million people have signed up and it now has more than 200 national partners.
There is some evidence to suggest current measures are working, as the number of overweight under-1 0s has remained at around 30% in the last decade and could be ‘levelling off’.
But they are work if people sign themselves up and motivate themselves to follow the advice and make changes.
