Unpopular steps may need to be taken to tackle Scotland's problem with obesity, MSPs say.

Members of Holyrood's Health Committee said that while policies like restricting cars in towns and increasing parking charges were "politically unpopular", they could encourage people to be more active.

They have also asked the Scottish Government to consider whether regulations could be brought in on where products are placed in shops, to stop retailers promoting unhealthy foods.

In a letter to Aileen Campbell, the minister for public health and sport, committee members wrote: "We support a bold approach to the new obesity strategy and would encourage you to include options that may initially be unpopular as this could result in an important step towards balancing out health inequalities in Scotland."

They warned that unhealthy food is "more available and more heavily promoted [in Scotland] than in other countries" and said two-fifths of adults do not do enough exercise.

Almost two-thirds (65%) of adults in Scotland were overweight in 2015, including nearly a third (29%) who were obese, according to the committee.

Meanwhile, 28% of children were at risk of becoming overweight, with 15% at risk of obesity, they said.

The committee said that while "good policies" had been brought in to tackle obesity, they added that they were "not necessarily translating into healthy outcomes".
