A Scottish Government plan to ban junk food deals and limit adverts for unhealthy snacks has been welcomed by TV chef Jamie Oliver.

The proposals, which could also see a calorie cap applied to takeaway food, were announced by public health minister Aileen Campbell as she launched a new consultation designed to tackle Scotland's obesity crisis.

Oliver praised the Scottish Government for its "bold, brave and trailblazing move to transform our kids' diets" and urged Westminster to follow suit.

He said: "Holyrood has outlined plans for a multi-pronged obesity strategy, including new rules around the marketing and advertising of unhealthy food. This is an amazing step towards making sure the healthiest choice is the easiest choice - for everyone.

"Today, Scotland has set an example to the rest of the world. It has picked up the baton that Westminster dropped last year."

Figures from 2016 showed that two-thirds (65%) of adults in Scotland were overweight, including 29% who were obese - statistics which are "largely unchanged since 2008", the Government said.

The consultation states ministers are "minded to act to restrict price promotion on food and drink products which are high in fat, salt and sugar" such as multi-buy deals and temporary price promotions.

As TV and radio advertising is reserved, the Scottish Government pledged to "strongly press" Westminster to ban broadcast advertising of foods high in fat, salt and sugar before the 9pm watershed - with ministers in Edinburgh saying if the UK Government does not act it will demand these powers be devolved to Holyrood.

Ms Campbell said they would also consider if restrictions are needed over the advertising of such products in areas around schools and children's visitor attractions, as well as on buses and trains.

The Scottish Government will also spend more than £40m on "weight management interventions" for almost 100,000 people who have or are at risk of type 2 diabetes.

Meanwhile, a specific strategy for restaurants and takeaways will be published by summer 2018 and include "action on calorie labelling, portion size and calorie cap options, promotions and marketing".

There will be funding of £200,000 over the next three year to help small and medium sized food businesses make healthier products, while health visitors will also work with families to promote health eating.

Ms Campbell said: "We are putting forward a package of bold measures designed to help people make healthier choices, empower personal change and show real leadership. Now we need people who live, work and consume food and drink in Scotland to tell us what they think.

"As with our ground-breaking strategies on alcohol and tobacco, this is the start of a progressive plan of action, learning from our experience in Scotland and further afield, that will make a real, lasting difference to the country's health."
