What is obesity?
In 2022, over 890 million adults, representing 16% of adults worldwide, were living with obesity. The World Health Organization (WHO) defines obesity as a complex chronic disease characterised by excessive body fat that can harm health. Body mass index (BMI) and waist circumference measurements are commonly used tools for diagnosing obesity. However, while diagnosing obesity may be straightforward, its causes are often misunderstood and framed as solely personal lifestyle choices. In reality, obesity is influenced by many factors beyond individual behaviour, including genetic, environmental and societal determinants.
