Takeaway customers will be shown calorie counts for the first time under a drive to encourage healthier eating.
Up to 500 restaurants and take-away outlets which are served by Deliveroo will publish calorie contents online from next month.
They will include high street chains such as Burger King and KFC as well as independent curry houses, fish and chip bars and kebab shops.
The move by Deliveroo – the country’s second-largest takeaway provider – comes ahead of Government plans to force restaurants to print calorie counts on their menus.
Department of Health officials are considering making calorie labelling a legal requirement as part of their ongoing childhood obesity strategy.
But Treasury ministers are reportedly trying to block the measures, fearing they will be a huge burden for small firms.
A Government spokesman yesterday insisted they were still pressing ahead with plans to help families choose healthier foods when eating out.
From next month, Deliveroo will begin publishing calorie counts for 500 restaurants and takeaway outlets but by the end of the year they expect this number to rise to ‘several thousand’.
