Health secretary Alan Johnson has warned that nine out of ten people will be overweight by 2050, putting a huge burden on the NHS, unless today's children change their lifestyles.
Launching a new coalition 'Change4Life' today Mr Johnson said that obesity was the 'biggest public health challenge' that the country faced.
'If we don't take action now we will condemn our children to reduced life expectancy. That's why we are aiming to create a lifestyle revolution that will help families to eat well, move more and live longer. We can't start a revolution on our own-we need everyone from grassroots community clubs to multinational companies to join us,' he said.
The collation aims to involve thousands of local organisations, charities and public organisations to help parents and families lead a healthier lifestyle.
'Finger wagging and lecturing won't work, that's why Change4Life is designed to be supportive and helpful,' Mr Johnson added.
