Obesity is a chronic disease that is characterized by the accumulation of excess body fat to the extent that it causes negative health effects.

The condition results from an energy imbalance between the amount of calories consumed and the amount expended. Over time, this leads to a buildup of body fat, which can increase the risk of various health problems, such as diabetes, heart disease, stroke, and even some types of cancer.

In many developed countries, obesity has become a major public health concern due to its prevalence and associated health risks.

Prevalence of obesity in developed countries

According to data from the World Health Organization (WHO), the prevalence of obesity has been increasing in most developed countries over the past few decades.

For example, in the United States, the prevalence of obesity has more than doubled in the past 30 years. In 1980, only 15% of adults in the US were obese, while in 2016, the prevalence of obesity had risen to 39.8%. This trend is not unique to the US, as many other developed countries have also experienced an increase in obesity rates.
