Quite a few charts, pathways and other publications relating to obesity for healthcare professionals are available from the Dept. Of Health website for free download.
One that I picked out at random is a two page document dealing with raising the issue of weight with children. It discusses the idea of raising the issue, reassurance and agreeing next steps etc.
Other publications include:-
Obesity Care Pathway - Adults and Children & Young People
Care pathway for the management of overweight and obesity
Raising the Issue of weight in adults
Why weight matters card
Your weight your health: how to take control of your weight
Consultation on obesity care pathway and resources for primary care
Summary of comments consultation on obesity care pathway_adult
Guidance on food portion sizes to lose weight.
So you want to lose weight...... for good
Each of these publications are small and take just seconds to download.
