SCOTS will be urged to cut unhealthy snacks from their diet on at least one day each week in the latest campaign against obesity by the country's food watchdog.

Food Standards Scotland is calling on people to shun calorie-laden treats such as chocolate, sweets, cakes, crisps, biscuits and sugary drinks every Tuesday as part of its 'Treat-Free Tuesday' drive.

It comes days after an FSS report recommended curbing portion sizes and adding calorie information to menus to encourage people to eat more healthily when they are dining out.

The watchdog said the average consumer could eliminate up to 16,000 calories a year from their diet by giving up two chocolate biscuits and a can of sugary drink one day per week.

Dr Gillian Purdon, FSS Senior Dietary Advisor said: “Too many people treat themselves with unhealthy snacks they just don’t need. The fact is, all those little extras can add up to health problems for ourselves and our children in the longer term.

"Around one-third of children and around two-thirds of adults in Scotland are currently overweight or obese. It’s forecast that, unless things change, 40 per cent of adults in Scotland could be obese by 2030.

“A treat should be just that – something we enjoy which we have occasionally - but as a nation we have got into the habit of frequently having unhealthy snacks. Making changes to your diet might be easier than you think, so we’re calling on people in Scotland to commit to dropping unhealthy snacks and treats every Tuesday as a simple, achievable way to start cutting out unnecessary snacking.”

FSS’s healthy eating marketing campaign ‘Change our Future’ will run from today on television, online and on social media, promoted through the hashtag "treatfreetuesday", designed to encourage people to make changes to their diet.
