Obesity management in primary care should begin with lifestyle interventions for patients ready to engage in behavior change. Using the 5As counseling model (assess, advise, agree, assist, arrange) in a patient-centered, nonjudgmental manner enhances motivation and adherence. Comprehensive lifestyle interventions (combining reduced caloric intake, increased physical activity, and behavioral changes) are most effective, typically achieving 5% to 10% weight loss over 6 months. Physicians should refer patients to multidisciplinary programs when possible or recommend digital or commercial alternatives with personalized feedback. Key components include setting specific, measurable, achievable, relevant, and time-based (SMART) goals; calculating caloric deficits; and promoting self-monitoring. Various dietary approaches can be effective and should be tailored to patient preferences. Physical activity lasting at least 150 minutes per week at moderate intensity or at least 75 minutes per week of vigorous activity is recommended. Digital tools (eg, apps, wearable trackers) can enhance engagement and outcomes. Physicians should also address barriers such as food insecurity, time constraints, and lack of support. Although adjunctive strategies such as sleep optimization and workplace modifications may be benefician, they should not replace core lifestyle changes.

Case 2. ST is a 41-year-old patient who comes to your office for an annual examination. He has no consequential medical history, but his current weight is 100 kg and body mass index (BMI) is 34.6 kg/m2, indicating class I obesity. He has a family history of diabetes and cardiovascular disease and wants to implement strategies to help prevent development of these conditions. He has been reading about intermittent fasting and wants to know if you would recommend it for him.

Lifestyle Interventions

Lifestyle interventions are recommended for all patients with obesity who are ready to engage in behavior change and establish goals toward weight loss.1 Physicians should ask for permission to discuss weight loss and implement tools such as the 5As counseling model2:

  • Assess (risk factors, readiness to change): ask for permission; assess for obesity-related comorbidities (diabetes, hyperlipidemia, hypertension, obstructive sleep apnea); screen for social determinants of health (eg, housing, food security); assess patient motivation
  • Advise (benefits of lifestyle change and weight reduction): reduce bias and ensure a supportive environment; discuss obesity as a chronic disease, not a personal failure; review health risks of obesity; personalize benefits of weight loss to patients
  • Agree (SMART [specific, measurable, attainable, realistic, time-based] goals, recommendations): answer patient questions and validate concerns; collaborate on SMART goals for behavior change and weight loss; provide recommendations for physical activity and reduced-calorie diet
  • Assist (treatment options, shared decision-making): offer comprehensive lifestyle intervention and refer to a program if accessible; personalize dietary approach to patient preferences; discuss other treatments, including pharmacotherapy or surgery (if indicated)
  • Arrange (follow-up to create accountability, feedback, support): provide adequate support and follow-up; refer to dietitian, weight management program, bariatric surgery (if indicated); monitor progress; adjust treatment plan as needed

Use of this model or similar framework with a patient-centered approach is associated with higher likelihood of patient motivation to lose weight and intentions to eat healthier and exercise.3 Using a judgment-free approach can improve likelihood of successful weight loss.4 Even if patients pursue a more intensive approach to weight loss (eg, pharmacotherapy, metabolic bariatric surgery), making sustainable lifestyle changes is essential during weight loss and maintenance.
