A third of the world's population is obese

Nearly a third of the world's population is obese or overweight, and a growing number of people are dying of problems related to the global public health crisis, according to one study.

According to research, four million people died as a result of cardiovascular diseases, diabetes, cancer, and other weight - related diseases in 2015, thus increasing the weight of deaths associated with obesity by 28% from 1990.

In 2015, overweight affected approximately 2.2 billion people, equivalent to 30% of the world's population.

Nearly 108 million children and more than 600 million adults have been named obesa, having a body mass index (BMI) over 30, was cited in the research that has been extended to 195 countries.

BMI is estimated to divide a person's weight into a pound by its square length and is an indication of whether the person has a healthy weight.

If the body mass index is above 25, it shows overweight, over 30 shows obesity, and over 40 shows pathological obesity.

According to the World Health Organization, obesity has more than doubled since 1980, reaching epidemic proportions.

Children's obesity rates are growing faster than in adults in many countries, including Algeria, Turkey and Jordan, the study shows.

Meanwhile, almost 800 million people, among them 300 million children, go to bed hungry for each evening, according to the United Nations, writes Klenmacedonia. Experts say the poor diet and sedentary life are the main causes of the growing number of overweight people.

Urbanization and economic development have increased the obesity rate even in poor countries, where some of the population does not have enough to eat. People seem to be changing traditional vegetable - rich meals with refined food.

People are increasingly consuming processed foods, which are rich in sugars and fats and are performing less physical exercise, said Boitshepo Bibi Giyose, a nutritionist in the United Nations Organization.
