NICE NG 7
The National Institute for Health and Care Excellence (NICE) provides national guidance and advice on health and social care in England.
Public Health role since 2005.Guidance is aimed at a wide range of
stakeholders including the NHS, local authorities and the wider health community.
Existing guidance
Obesity CG 43 (2006) and Obesity update CG 189 (2014)
Lifestyle weight management in adults (2014) and children (2013)
BMI and waist circumference – BME groups (2013)
Obesity – working with local communities (2012)
Weight management before, during, after pregnancy (2010)
Updating Obesity (2006)
‘Information for the public’
• Clearer on aims and target audience
• New evidence e.g. sugar sweetened drinks, sleep
• Nuanced recommendations
• Practical examples
Scope
• Aimed at practitioners who need advice on behaviours that help people maintain a healthy weight.
• Focus on individually modifiable behaviours.
• Supports other NICE guidance including e.g. preventing CVD or type 2 diabetes.
• Includes children and adults
• Excludes weaning, pregnancy and management of obesity.
Guideline developmentIndependent committee with range of expertise
Assessment of evidence: Systematic review of reviews on 64 factors Qualitative evidence on communicating advice Consideration of relevant economic models
Stakeholder consultation
Overarching messagesCombination of increased physical activity and healthier
eating – energy balance.
Existing advice on diet and physical activity.
Avoiding extreme behaviours (e.g. excessive exercise or avoiding all carbohydrates).
Identifying perceptions, habits or situations that may undermine efforts to maintain a healthy weight.
Physical activity
• All activity likely to be helpful – range of definitions used in evidence.
• Good evidence for walking (particularly brisk walking) and cycling.
• Good evidence for being active during leisure time, part of daily life, play.
• Limited review level evidence on sedentary behaviours; strong relationship with TV viewing.
Additional adviceAdults • do not exceed recommended amounts of alcohol
Children • active at every opportunity• family meals• enough sleep
General• Self monitoring – e.g. pedometer, regular
weighing• Robust sources of information
Communicating messages
The broad range of benefit including ‘non health’
Even small improvements are likely to be helpful
Important for people currently a healthy weight weight gain not inevitable No single factor
Tailor messages Clear, consistent, specific, non judgemental

Weight Regain ; is it inevitable?
20% of individuals attempting weight loss are able to achieve and maintain 5% weight reductions for at least 1 year. Among successful weight losers, various studies indicate that more than 60, 35, and 19% of individuals are able to maintain 10% weight reductions for 1, 3, and 5 years, respectively.Maintenance of weight loss for ≥ 2 years is protective against subsequent regain; by 2 years the likelihood of regaining 2.6 kg in the coming year is only 50%; by 5 years the likelihood drops to 27%

Self regulation mediators (1)
A comprehensive search of peer-reviewed articles, published since 2000
Conducted on electronic databases and journal reference lists.
Experimental studies were eligible if they reported intervention effects on ;hypothesized mediators (self-regulatory and psychological mechanisms) and the association between these and the outcomes of interest (weight change, physical activity, and dietary intake).
Self regulation mediators (2)
35 studies,Best predictors;
higher autonomous motivationself-efficacyself-regulation skills
positive body image and flexible eating restraint may additionally improve outcomes.
Long-term weight loss maintenance
Wing R R and Phelan S.Am J Clin Nutr 2005;82 (suppl) 222S-5S 6 key strategies ;1.High levels P A2.Diet low in calories and fat3.Eating breakfast4.Self-monitoring weight regularly5.Maintaining consistent eating pattern6.Catching ‘slips’ before large regains
What should we discuss with clients?
1. Set realistic goals both for target weight and maintenance2. Establish regular eating patterns3. Eat breakfast 4. Avoid high fat/sugar foods5. Alcohol in moderation6. Don’t deviate from healthy eating for more than 3 days7. Plan a strategy to help with relapses-ask for help if needed8. Note what has worked for you in the past and return to it9. Consider a support group (NHS or commercial)10.Maintain high level of PA 11.Aim to maintain your new weight for 2 years if possible
Discharge plan
Consider a written plan drawn up in conjunction with the client
Check they have realistic expectations Encourage self monitoring weight, activity
(pedometer/fitbit/app etc) Consider support group Offer up to date information and reliable long term resources;
