Update information

Update information

January 2025: This guideline updates and replaces NICE's guidelines on:

  • Preventing excess weight gain (NG7, published March 2015).

  • Obesity: identification, assessment and management (CG189, published November 2014)

  • Weight management: lifestyle services for overweight or obese adults (PH53, published May 2014)

  • Weight management: lifestyle services for overweight or obese children and young people (PH47, published October 2013)

  • BMI: preventing ill health and premature death in Black, Asian and other minority ethnic groups (PH46, published July 2013)

  • Obesity: working with local communities (PH42, published November 2012)

  • Obesity prevention (CG43, published December 2006)

We have reviewed the evidence and made new recommendations, if relevant, on:

  • prevention in schools and nurseries

  • general principles of care

  • identification, assessment and referral

  • behavioural overweight and obesity management interventions

  • dietary advice

  • specific advice for people from ethnic minority backgrounds

  • multidisciplinary teams for children

  • raising awareness of interventions

  • planning and funding services and interventions.

We have merged and deleted some recommendations to:

  • avoid duplicating other NICE guidance

  • remove duplication or improve alignment between recommendations from different guidelines.

We have also made some changes without an evidence review (marked as amended 2025) to:

  • remove strategies that are no longer standard practice or considered appropriate

  • align recommendations with changes in service structure

  • emphasise respectful, non-judgemental care and communication, and the need to take into account wider determinants of overweight and obesity.

For more information about how the original guidelines were amalgamated and any changes that were made to the recommendations, see the summary of deleted and amended recommendations.

Minor changes since publication

March 2025: We added links to the NHS BMI calculator for adults and the NHS calculator for measuring waist-to-height ratio in children aged 5 and over and young people to the section on identifying and assessing overweight, obesity and central adiposity.

February 2025: We have changed references to weight-loss medicines to say weight-management medicines in the section on medicines and surgery.
