“Buy one get one free” deals on unhealthy food will be banned as part of the government’s bid to tackle obesity in England.
The plan will also include restrictions on where foods high in fat and sugar can be promoted in store and new rules for displaying calories on menus.
A ban on junk food adverts before 21:00 has been confirmed – for the whole UK.
Boris Johnson said the plans would help “reduce our health risks and protect ourselves against coronavirus”.
The prime minister will unveil the strategy later amid growing evidence of a link between obesity and an increased risk from Covid-19.
Government statistics showed nearly 8% of critically ill patients in intensive care units with the virus have been morbidly obese, compared with 2.9% of the general population.

- GPs to prescribe cycling in new obesity strategy
- Obesity increases risks from Covid-19, experts say
- Has Covid-19 exposed UK’s underlying ill health?
The move marks a change in stance by the prime minister, who has previously criticised levies on foods high in salt, fat and sugar – and described his views on tackling obesity as “libertarian”.
But Mr Johnson’s experience in intensive care during his treatment for Covid-19 is thought to have contributed to his changing position.
Along with the ban on TV and online adverts before the watershed, the government said it would hold a consultation on whether to stop fast food adverts online altogether.
Labelling of calories on menus will apply to any restaurant, cafe or takeaway chain with more than 250 employees, and another new consultation will be launched around plans to provide the same information for alcoholic drinks.
Sue Eustace, director of public affairs at the Advertising Association, said the “extreme” and “unnecessary” measures would have little effect in reducing obesity, and warned they could have “wide ranging ramifications” for food businesses and online publishers trying to financially recover from the pandemic and the lockdown.
She told BBC 5 Live’s Wake Up to Money programme: “We have some of the strictest [advertising] rules in the world already and children’s exposure to high fat, salt, and sugar adverts on TV has fallen by 70% over the last 15 years or so, but there’s been no change to obesity, so we don’t think these measures are going to work.”
She warned that the measures could impact a “whole range” of household products that people do not necessarily view as junk food, and questioned whether this would restrict businesses like local fish and chip shops from putting their menus online for customers.
Am I overweight?
The NHS says most adults with a body mass index (BMI) of 25 to 29.9 are overweight, while those with a BMI of 30 to 39.9 are classed as obese.
Body mass index is calculated by dividing a person’s mass in kilograms by the square of their height in metres.
Another measure of excess fat is waist size – men with a waist of 94cm or more and women with a waist of 80cm or more are more likely to develop obesity-related problems.
Dr Alison Tedstone, chief nutritionist at Public Health England, also backed the strategy, saying it would “save lives”.
“These bold measures will help us tip the scales on obesity. The argument for action is the clearest it’s ever been,” she added.
Michelle Mitchell, Cancer Research UK’s chief executive, said: “This is a landmark day for the nation’s health.
“Being overweight or obese puts people at risk of many diseases, including 13 different types of cancer, and disproportionately affects people from poorer backgrounds so the plan will hugely help to level-up the country and build a healthier population.”
Professor Dame Parveen Kumar, chairman of the British Medical Association’s Board of Science, said: “The BMA has long been calling for new ways to tackle obesity and we are delighted to see that the government has sat up and listened.
“What we need now is for this strategy to be actioned as quickly as possible, with the promised expansion of NHS services delivered in full, with adequate resources and funding, to ensure that those struggling with their weight can get the support they need and deserve.”
But Adam Briggs from the Health Foundation said: “There is little sign of policies that will address the root causes of obesity.”
