Campaigner suggested that obesity in children can be attributed to bad food, lax advertising and no place for them to play.

Recent NHS figures showed that between 1995 and 2007 there was a rise in the number of obese children aged two to fifteen.

The Government researchers have predicted that the number of obese children will keep rising. They said that half the number of boys aged six could be obese by 2050 and one fifth of the number of girls in a similar age group.

Obesity is linked to most of the diseases like Type-2 diabetes, various types of cancers and heart diseases as well as a reduced span of life.

Tam Fry, from the National Obesity Forum says that the problem lies with the failure in the balance of energy input and output. The food consumed is of a high fat content and high sugar but the amount of exercise needed to burn these calories is missing.

He blamed the society for not having a perfectly balanced system in place for the right find of food and ample play area. He strongly urged the Government to take serious steps to have proper regulations of the kind of food which has a high nutritional value.

Mr Fry added: "We have to do really radical things to make play space. We have to build parks, we have to rejuvenate the wonderful parks that the Victorians created that have been allowed to go to rack and ruin. The list is endless."
