Obesity places a significant burden on people affected, increasing their risk of unintended health consequences,5 and reducing their life expectancy.6
Percentage of adults aged 18+ defined as having obesity in 2016 (people with obesity defined as BMI >30):7
Despite the scientific community recognising obesity as a multifactorial chronic disease which requires long-term management,8,9 it is often considered to be the responsibility of the individual by governments, healthcare systems and even people with obesity.10,11
Rising obesity levels have also had an adverse effect on society and economic prosperity, causing a decrease in economic activity through loss of productive life years,12 and by placing increasing demands on healthcare systems.13
Approximately 46% of people with a BMI<40 have at least five related complications, rising to 55% of individuals with a BMI>60.5 These complications can include type 2 diabetes, cardiovascular disease and certain cancers which all require a substantial level of care and medication.2
