A new awareness week to promote sustainable, healthy living starts today (9 January).
The organisers of the week, which is supported by the National Obesity Forum among others, are asking the UK to join in a healthy national New Year's resolution.
'Do something good for "U"' in JanUary, formerly known as the National Obesity Awareness Week, is asking everyone to make small changes in the way they live to improve the country's long-term health.
They suggest changes to eating habits, such as cooking more healthily and avoiding snacks, drinking more water or being more physically active.
And they are calling on the government and businesses to facilitate and support these changes.
New Year's resolutions can be posted on the JanUary website or shared using a pledge card via Facebook, Twitter or Instagram and the hashtag #dosomethinggoodforU in a bid to encourage friends and family to do the same.
'It's not about making some major change that you'll struggle to stick to. It's about doing something sustainable that'll help you in the long term,' according to the JanUary website.
Events, activities and promotions are taking place across the country.
The week ends on 15 January.
