IM14.11-14 | Obesity Counselling and Treatment — Summary & Reflection

KEY TAKEAWAYS

Obesity counselling and treatment follows an evidence-based stepwise approach:

Counselling: Use the 5As framework (Ask permission, Assess, Advise, Agree goals, Assist); apply person-first non-judgmental language; use motivational interviewing to explore barriers; match intervention to Stages of Change. Common barriers: shift work, family food preparation, financial constraints, emotional eating, physical limitations — address with curiosity, not judgement.

Lifestyle modification: caloric deficit 500–750 kcal/day below TDEE; reduce SSBs, refined carbohydrates, cooking oil; increase fibre, protein, vegetables; ≥150–300 min/week moderate aerobic activity + resistance training; behavioural tools (self-monitoring, SMART goals, stimulus control, CBT for emotional eating).

Pharmacotherapy: indicated when lifestyle modification for ≥3–6 months fails to achieve ≥5% weight loss AND BMI ≥27.5 with comorbidities OR ≥32.5 (Asian-Indian).
- GLP-1 RAs (liraglutide, semaglutide): preferred in T2DM + obesity; mean weight loss 8–15%; side effects mainly GI; contraindicated in MTC/MEN2.
- Orlistat: pancreatic lipase inhibitor; ~2.5–3.5 kg additional weight loss vs placebo; GI side effects (steatorrhoea, faecal urgency); supplement fat-soluble vitamins separately.

Bariatric surgery: BMI ≥37.5 or ≥32.5 with major comorbidities (Asian-Indian); after 6 months structured lifestyle programme. Sleeve gastrectomy: T2DM remission 50–60%. RYGB: T2DM remission 60–80% via restriction + malabsorption + GLP-1 surge. Lifelong nutritional supplementation required post-RYGB (iron, calcium citrate, B12, vitamin D).

Prevention: SSB reduction, whole grains, 30 min daily walking, front-of-pack labelling, SSB tax, school/workplace programmes. Educate patients: 5–10% weight loss is medically meaningful. Asian-Indian threshold for screening: BMI ≥23 kg/m².

REFLECT

Return to Ramesh from the opening hook — the bus driver working 4 AM to 8 PM who leaves every consultation feeling like a failure. He does not need another diet sheet. He needs a clinician who listens to the specific constraints of his life and helps him find the two or three changes that are both clinically meaningful and actually achievable within his schedule. Maybe that is switching from two colas to water on his route. Maybe it is a 15-minute walk at lunchtime. Maybe it is referral to a GLP-1 agonist that reduces his hunger so that dietary restraint under fatigue becomes possible. What would you say to Ramesh at the start of this consultation — not to prescribe, but to open the conversation in a way that makes him feel that this time, something might actually change?
