Even as the prevalence of obesity was rising rapidly across the world, health professionals were unclear as to whether obesity should be labelled as a disease in itself or merely as a risk factor for other diseases. A distinction was notionally drawn between “overweight” and “obesity”. Recognition of amplified health risks posed by visceral or abdominal obesity, as distinct from the risk posed by general obesity, brought a new dimension to debates around obesity as an omnibus term.

As scientists sought to define obesity through quantifiable anthropometric measures, debates raged over whether the problem arose from personal behaviours of eating and exercise or from commercial forces that propelled changes in patterns of food consumption through their manufacturing and marketing practices. Attributing obesity to an individual’s gluttony or indolence led to body shaming and social discrimination. And now, with powerful new weight-loss drugs emerging recently, calls to treat obesity as a disease have become louder.
