Health Secretary Andrew Lansley has managed to sign up major companies including Coca-Cola, Pepsi Co, Mars, Nestle and supermarket chains such as Tesco and Marks & Spencer to reduce the number of calories in their products.
Lansley said that the "calorie reduction pledge" will cut as much as 5 billion calories from the nation's daily diet. However experts have criticized the campaign as it does not include popular fast food chains such as KFC and McDonalds.
Shadow Public Health Minister Diane Abbott called the campaign worthless without the participation of the big firms, "None of the promises will happen before the end of 2014. The fight against the obesity epidemic cannot wait two years. We already have the fattest children in Europe," she told the Daily Mail.
McDonalds explained its stand on the campaign by saying that it already has calorie information for customers.
