About this guideline
It does not cover weaning, the particular needs of women during pregnancy or people who have conditions that increase their risk of becoming overweight or obese. It also does not cover interventions to:
prevent children or adults becoming overweight or obese
identify or assess people who are overweight or obese
manage the weight of people who are overweight or obese.
(See related NICE guidance for other recommendations that may be relevant to identifying, preventing and managing overweight and obesity.)
The absence of any recommendations on interventions that fall within the scope of this guideline is a result of lack of evidence. It should not be taken as a judgement on whether they are cost effective.
The recommendations are based on the best available evidence. They were developed by the Public Health Advisory Committee (PHAC).
Members of the PHAC are listed in membership of the Public Health Advisory Committee and the NICE project team.
For information on how NICE public health guidelines are developed, see the NICE public health guideline process and methods guides.
The evidence that the PHAC considered included:
Review 1 'An evidence review of modifiable diet and physical activity components, and associated behaviours', was carried out by Bazian. The principal authors were: Alicia White, Sarah Caton, Rob Davies, Alex Bhatti, Laura Johnson, Simon Sebire.
Review 2 'Qualitative evidence review of the most acceptable ways to communicate information about individually modifiable behaviours to help maintain a healthy weight or prevent excess weight gain' was carried out by Bazian. The principal authors were: Rob Davies, Alicia White, Sarah Caton, Alex Bhatti, Laura Johnson, Simon Sebire.
'Maintenance of a healthy weight and prevention of weight gain in children and adults. Cost effectiveness considerations from a population modelling viewpoint' was produced by NICE. The principal author was Alastair Fischer.
In some cases the evidence was insufficient and the PHAC has made recommendations for future research. For the research recommendations and gaps in research, see recommendations for research and gaps in the evidence.
The draft guideline, including the recommendations, was released for consultation in September 2014. At its meeting in November 2014, the PHAC amended the guideline in light of comments from stakeholders and experts and the fieldwork. The guideline was signed off by the NICE Guidance Executive in February 2015.
The recommendations should be read in conjunction with existing NICE guidance unless explicitly stated otherwise. They should be implemented in light of duties set out in the Equality Act 2010.
The guideline is available on NICE's website. The recommendations are also available in a pathway on obesity for professionals whose remit includes public health and for interested members of the public.
NICE produces guidance, standards and information on commissioning and providing high-quality healthcare, social care, and public health services. We have agreements to provide certain NICE services to Wales, Scotland and Northern Ireland. Decisions on how NICE guidance and other products apply in those countries are made by ministers in the Welsh government, Scottish government, and Northern Ireland Executive. NICE guidance or other products may include references to organisations or people responsible for commissioning or providing care that may be relevant only to England.
NICE guidelines can help:
Commissioners and providers of NHS services to meet the requirements of the NHS outcomes framework 2013–14. This includes helping them to deliver against domain 1: preventing people from dying prematurely.
Local health and wellbeing boards to meet the requirements of the Health and Social Care Act (2012) and the Public health outcomes framework for England 2013–16.
Local authorities, NHS services and local organisations determine how to improve health outcomes and reduce health inequalities during the joint strategic needs assessment process.
NICE has developed tools to help organisations put this guideline into practice.
