Weight
management - some evidence
What are the most effective ways for weight management? Is there any medical evidence?
- A multi-component commercial group programme may be more effective than a standard self-help programme
- There is some evidence that computer/email/internet-based programmes accompanied by greater ongoing support – in person, by post or email – may be more effective than those without
- The effectiveness of commercial and computer-based weight loss programmes in men remains unclear
- It remains unclear whether the branded commercial group programme for which there is evidence of effectiveness (WeightWatchers) is more or less effective than other branded commercial programmes
- There is no strong evidence to support the use of meal replacement products over a standard low-calorie diet
- There is limited evidence that interventions to manage obesity based in workplace settings can be effective, though weight loss may be small in the long term
- There is limited evidence that interventions provided by school staff can aid the management of obesity in children and young people, at least in the short term, but this may be less effective than a more intensive intervention delivered in a clinical setting
- There is some evidence that home-based interventions may be more effective when accompanied by behaviour modification material and ongoing support
NICE have stated that weight loss programmes (including commercial or self-help groups, slimming books or websites) are recommended only if they:
- are based on a balanced healthy diet
- encourage regular physical activity
- expect people to lose no more than 0.5-1 kg (1-2 lb) a week
Programmes that do not meet these criteria are unlikely to help people maintain a healthy weight in the long term
People with certain medical conditions - such as type 2 diabetes, heart failure or uncontrolled hypertension or angina - should check with their general practice or hospital specialist before starting a weight loss programme
