Uniting the World Against
Obesity
The International Society of Obesity (ISO) is the global scientific society for obesity medicine professionals — advancing research, education, and evidence-based practice to transform care for the 1 billion people living with obesity worldwide.
A Global Platform for Obesity Medicine
The International Society of Obesity (ISO) is a collaborative scientific society that brings together clinicians, researchers, policymakers, and allied health professionals to address the complex, multifactorial challenge of obesity.
ISO fosters cross-disciplinary collaboration — uniting endocrinologists, bariatricians, dietitians, psychologists, and public health professionals under one global banner. We translate science into practice, practice into policy, and policy into lasting population impact, with our person first philosophy.
Incorporated in Montana, USA, with a founding leadership team led by internationally recognised clinicians, ISO is committed to elevating the standard of obesity care in every corner of the world.

The Barocene Era: Our World Is Facing an Obesity Crisis
Obesity is no longer a lifestyle issue — it is a complex, chronic, relapsing disease. The science demands that we treat it as one.
Obesity influences and impacts our very existence. Despite being the second leading preventable cause of death globally, obesity remains undertreated, underfunded, and misunderstood. ISO exists to bridge the gap between science and systems — accelerating action at every level of care.
