The levels of obesity in the UK - and indeed, across the world - are of great concern.
That is why Public Health England is putting in so much effort to attempt to reverse the trend.
The challenge of obesity is at the heart of current debate about the health of the nation and we are working closely with local authorities, the NHS and the voluntary and community sector to tackle this complex issue.
