Supermarkets should be redesigned to have fruit and vegetables by the door and live cooking demonstrations for healthy meals, experts say.
The Royal Society for Public Health has released a blueprint of how supermarkets should be laid out to help fight obesity.
Smaller sections of the shop should be dedicated to alcohol, cakes and crisps, with more space for fruit and veg, the body says.
Research by the RSPH and Slimming World found more than a third of adults impulse buy unhealthy snacks when they're lured in by special offers.
And the layout of supermarkets could be to blame, the organisations said as they call for shops to do more to help people make healthy choices.
On the redesigned shop floor fruit and vegetables, potatoes, rice, bread and cereal and pasta take pride of place in the first aisles by the entrance.
This was compared to a mock-up of a typical supermarket as they are now, showing desserts, pizza and ready meals, snacks and the bakery in the first rows.
The RSPH report also removes what it shows to be a halo of sweets and chocolate around the checkout area where people may be tempted while waiting for a till.
They hope doing more to promote healthy foods in supermarkets will help tackle rising rates of obesity in the UK.
Two thirds of adults in the UK are now overweight and about a third of them are obese. Around 30 per cent of children are overweight, too.
Being fat increases the risk of various health problems including the hip and knee joints deteriorating and the development of type 2 diabetes, heart disease and cancer.
The Government estimates the NHS spends more than £6billion per year treating people with obesity-related health problems. And the wider costs to society are thought to be more like £27bn per year as it affects people's job prospects and ability to work due to mental health problems.
