Obesity today

Obesity in the world

Obesity is defined by the WHO as a Body Mass Index (BMI) above 30kg/m² and refers to excessive fat accumulation.

38% of the world's population is currently overweight or obese

Obesity is a disease caused by the excessive accumulation of body fat (BMI > 30kg/m²) and has adverse health consequences, leading to associated health conditions and reduced life expectancy. Over the last forty years the prevalence of obesity globally has tripled and is expected to reach 50% of the world population by 2035.

29% of the population in Greece is currently obese

More than half of adults in Greece are obese or overweight, ranking Greece among the countries with the highest levels of obesity in Europe.

From 2020-2035 the projected annual increase in adult obesity is forecast at 2%. 

In terms of economic impact, obesity and co-morbidities place a particular burden on the national health system, as they significantly increase the related costs. Its impact on national GDP in 2020 is estimated at 1.7%, which is considered very high, with a projected upward trend.

Genetics is only one aspect of the risk of obesity. Lifestyle factors such as diet, physical activity, sleep, stress management and overall behaviour are also crucial.
