This decision was taken as part of Boris Johnson's 'Better Health' campaign, aimed at tackling obesity across Britain.
'Buy one get one free' deals on unhealthy food will be banned and restrictions are to be placed on where foods high in fat and sugar can be promoted in-store, and new rules have been introduced to display calorie menus. A ban has also been placed on displaying junk food adverts before 21:00.
Boris Johnson also unveiled this plan as there is growing evidence of a link between obesity and an increased risk from Covid-19. The BBC reported that the government statistics showed nearly 8% of critically ill patients in intensive care units with the coronavirus have been morbidly obese, compared with 2.9% of the general population.
