Abstract

Obesity has emerged as one of the most pressing global public health challenges of the 21st century. Obesity has reached epidemic proportions worldwide, with over 1 billion people classified as obese in 2022, representing 13 % of the global population. Since 1975, obesity rates have tripled, and projections indicate that by 2035, around 1.9 billion adults-approximately 25 % of the world's population-will be affected. Looking further ahead to 2050, it is estimated that 3.80 billion adults, representing more than half of the anticipated global adult population, will be living with overweight or obesity. The increasing burden of obesity is associated with an alarming rise in non-communicable diseases, including type 2 diabetes, cardiovascular diseases, and multiple cancers, collectively contributing to over 5 million deaths annually. Obesity is driven by complex interactions between genetic, behavioral, environmental, and socioeconomic factors, with rapid urbanization and globalization accelerating the consumption of high-calorie diets and sedentary lifestyles. While historically prevalent in high-income nations, obesity rates are now rising most rapidly in low- and middle-income countries (LMICs), with over 70 % of obese individuals living in developing nations. The economic costs of obesity are staggering, with projections estimating a global financial burden of $4.32 trillion per year by 2035, equivalent to 3 % of the global GDP. This article explores the epidemiology, determinants, health implications, and policy responses to obesity, emphasizing the urgent need for multisectoral strategies to mitigate its impact. Public health initiatives, taxation on sugar-sweetened beverages, improved food regulations, and increased physical activity promotion are essential components of evidence-based interventions. Addressing the obesity crisis requires global cooperation to implement sustainable, long-term strategies targeting both prevention and treatment.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
