Behavioural Science is Crucial in the GLP-1 Era GLP-1s are transforming the treatment landscape for obesity and metabolic disease. Yet for all their clinical promise, their full impact depends on something that can’t be prescribed, manufactured, or titrated — human behaviour. Here's how behavioural science and GLP-1s act in partnership: 1️⃣ Adherence isn’t just about reminders Even the most effective medication can fail if patients disengage. Real-world GLP-1 discontinuation rates can exceed 50%, often for behavioural, not biological reasons: 🎯 Motivation fades once early goals are reached (Goal Gradient Effect) 😟 Side-effect fears amplified by social narratives 🤔 Identity conflicts (“If I need a drug, have I failed?”) 2️⃣ Overcoming stigma and self-blame People with obesity can internalise stigma, making treatment emotionally complex. 🖼️ Behavioural framing can reframe obesity as a chronic condition, not a moral failure. 💬 When HCPs use motivational interviewing and empathetic messaging, conversations spark engagement, not resistance. 3️⃣ Bridging intention and action Behavioural science closes the gap between knowing and doing. It makes healthy behaviour the easiest choice through friction reduction and smart design. 📲 A timely digital nudge normalising mild nausea (“Here’s what helps”) can prevent early drop-off. 4️⃣ Personalisation beyond the ,olecule Not all disengagement looks the same. 🧭 Behavioural segmentation — mapping beliefs, emotions, and contexts — enables tailored journeys that meet people where they are. ⚙️Behavioural science is the engine behind true personalisation: blending emotional intelligence with clinical precision. 5️⃣ Designing for long-term change Sustained outcomes require lasting habits. 💪 Behavioural insights help patients move from medication to maintenance, reinforcing self-efficacy and identity (“I manage my health”). The goal isn’t just adherence to medication; it’s adherence to progress. GLP-1s may be a scientific breakthrough, but behavioural science determines whether they become a societal one. Success will depend not only on molecules and mechanisms, but on mindsets, motivation, and meaning. Would love to hear what my behavioural science and obesity colleagues think.
