The 5 A’s Model for Behavior Change and Its Use for Weight Management in Practice (22)
1. Assess • Assess patients for obesity or overweight with metabolic risk factors • Assess for patients’ readiness and ability to make change at this time 2. Advise • Advise patients about the increased risks of cardiovascular disease with excess adiposity • Advise patients of the health benefits of weight loss and lifestyle change 3. Agree • Agree with patients on a quantifiable and achievable weight loss goal that will lead to health benefits (i.e., a goal of losing 5% of initial body weight in 6 months) 4. Assist • Assist patients in defining a weight management strategy (i.e., practice-based weight loss counseling vs. referral to a weight loss program) 5. Arrange • Arrange follow-up to create a structure for accountability and feedback on progress - TABLE 3.
