- BMI of ≥40 kg/m2

Effective partnership is essential for long-term success2
The “5 As” model can help you discuss weight management with your patients9

The graphic shows a conversation flow based on the "5A" model. The "5A" model is an easily implemented evidence-based and behavior-oriented intervention strategy. It can help to increase the success of weight management in primary care. 6
- Ask: Ask for permission. Ask patients for permission to talk about body weight together. Don't judge and explore readiness for change.
- Assess: Assess the current situation. Measure BMI, waist circumference and degree of obesity. Record possible causes and complications caused by excess weight.
- Advise: Educate and advise patients about the health risks of obesity and the benefits of moderate weight loss and advise them on long-term strategies and treatment options.
- Agree: Agree on specific goals. Talk to patients about realistic expectations. Agree on realistic goals for weight loss, behavior change, and other details of the treatment plan.
- Assist: Support. Identify and address potential obstacles. Provide information, support in finding suitable co-treatment partners and arrange regular follow-up appointments.
