In most OECD countries that collect self-reported weight data, more than half of adults are overweight or obese. Obesity prevalence is particularly high in the United States, with over a third of respondents identifying as obese in 2023. This highlights the significant public health challenge obesity poses and the need for comprehensive approaches to addressing the issue.
According to the World Health Organization, a body mass index (BMI) of over 25 is considered overweight, while over 30 indicates obesity. It's essential to understand that obesity is more than just poor lifestyle choices; factors including genetic predisposition and environmental influences play a crucial role. Therefore, addressing obesity requires a nuanced understanding of these various contributing elements.
