Lifestyle change remains the foundation of obesity treatment — but for many patients it is not sufficient on its own. This guide sets out the rational, evidence-based use of weight-loss medication as part of a comprehensive and individualised approach.
Secrets of a Healthy Liver Series
Medical Treatment of Obesity
Lifestyle change is the cornerstone of obesity treatment — and for a substantial share of patients, it is not enough on its own. Prof. Seyed-Moayed Alavian sets out how modern pharmacotherapy fits alongside it: which patients it suits, how it should be monitored, and where its limits lie.

About this book
Over recent decades obesity has moved from an individual concern to one of the most significant global public health crises. Its rising prevalence reduces quality of life and drives a substantial increase in non-communicable disease — type 2 diabetes, hypertension, cardiovascular disease, non-alcoholic fatty liver disease, musculoskeletal disorders, and certain cancers — making it a leading contributor to premature mortality and a major burden on health systems.
Healthy nutrition, regular activity, adequate sleep, and stress management remain the cornerstone of treatment. But the evidence is clear that for a substantial proportion of patients these interventions alone do not achieve or sustain long-term weight loss. The complexity of body weight regulation — hormonal, neural, metabolic, and genetic factors, together with the body's adaptive response to weight loss — explains why so many people experience repeated treatment failure despite genuine effort.
In those circumstances, targeted pharmacotherapy can be an effective adjunct. Modern obesity medicines are not limited to appetite suppression: they act on hormonal pathways, satiety, energy metabolism, and eating behaviour. Their use demands adequate knowledge, appropriate patient selection, careful monitoring, and a clear-eyed understanding of adverse effects and limitations.
This book offers a scientific, current, and practical guide to using these medicines rationally — presenting pharmacotherapy not as a substitute for lifestyle change, but as one part of a comprehensive, individualised, and sustainable approach.
What the book covers
Why lifestyle alone often fails
The hormonal, neural, metabolic, and genetic mechanisms behind weight regain — and why that is not a failure of willpower.
How the medicines work
Effects on hormonal pathways, appetite and satiety, energy metabolism, and eating behaviour.
Patient selection
Who is likely to benefit, and the assessment that should precede any prescription.
Monitoring and safety
Adverse effects, limitations, and the follow-up that responsible prescribing requires.
An adjunct, not a substitute
How pharmacotherapy is integrated with nutrition, activity, sleep, and stress management.
Individual and public health
Applying obesity pharmacotherapy responsibly at the scale of a health system.
Important. Weight-loss medicines are prescription treatments. This book is educational and does not recommend, prescribe, or provide dosing guidance for any specific drug, and approved indications differ between countries. Any decision to start, change, or stop obesity medication belongs with a qualified clinician who can assess your history, other medicines, and possible adverse effects. Never obtain prescription medicines from unregulated sources.
