When we say the most obese countries in the world, we refer to the countries with the highest percentage of the population with unwanted or abnormal accumulation of fat, and large weights. But weight alone cannot determine the detrimental effects on the body. For example, a person with a height of 6 feet 2 inches and weighing 80 kg will be healthy compared to an 80 kg person with a 5 feet 6 inches height. So, to standardize the obesity and effect of weight, BMI is introduced. BMI or Body Mass Index is a simple index that takes weight and height into account. It is defined as the person’s weight in kilograms divided by the square of the person’s height in meters, giving us a unit of kg/m².

For adults, the World Health Organization has defined the standard for overweight and obesity. If a person has BMI equal to or greater than 25, he is overweight. On the same lines, having BMI greater or equal to 30 makes one obese. The World Health Organization reports that worldwide obesity has tripled since 1975. In 2016, 1.9 billion people, or 39% of the worldwide population of the age of 18 and older were overweight (BMI is greater than 25). Similarly, 650 million or 13% of the global population were obese. Under the age of 5, 39 million children were obese, while 340 million of the age of 5-19 are obese or overweight in the world.

The number of deaths caused by obesity is more than deaths by underweight in these obese countries. 8% of the total deaths, about 4.72 million, in 2017 were caused by obesity, increasing from 4.5% in 1990. Fiji, Bahrain, and American Samoa are the most affected countries with 29.43%, 25.69%, 23.53% of deaths caused by obesity respectively.

Among the causes of obesity, many are associated with an imbalance between the intake and expenditure of calories. The increase in calorie intake is mainly due to eating habits having energy-rich foods like sugar-sweetened drinks and unnecessary fats and carbohydrates.  From one report, the global average calorie intake has increased from 2,200 kcal per day in the 1960s to 2,800 kcal per day in 2013. This recent increase in food consumption has resulted due to brands like The Coca-Cola Company (NYSE: KO), PepsiCo, Inc. (NASDAQ: PEP), Mondelez International, Inc. (NASDAQ: MDLZ), McDonald’s Corporation (NYSE: MCD), and Yum! Brands, Inc. (NYSE: YUM), having high sugar content in their products, causing the human body to process sugars and store them as fat.

The other main factor is the decrease in physical activities. Our lives have become more sedentary, including sitting all day in front of computer screens. Moreover, the decrease in walking due to better transportation and ride-hailing companies like Uber Technologies Inc.(NYSE: UBER) has also led to increasing obesity rates.

The health conditions like diabetes, stress, hyperthyroidism, among many other diseases, also contribute to the increase in weight.

Obesity can be reduced by calculating calorie intake. The fundamental step is to replace high sugar content with fresh fruits and vegetables. Obesity can also be controlled by doing physical exercises. The World Health Organization recommends that 150 minutes of walking spread through the day is enough for adults while for children, 60 minutes are enough.

On the societal level, obesity can be reduced by introducing policies that curb the usage of sugar. These policies include taxing sugar-based products, lowering the prices of artificial sweeteners, and restricting the marketing of sugar-rich food to children and teenagers. Making healthy food available and affordable to all is also a thing with significant outcomes.
