Obesity is known globally as an important human health problem. In both developed countries and developing countries, obesity is increasing day by day. In studies conducted by the World Health Organization (WHO), an increase of 10-30% in obesity has been reported in 10 years.
According to 2008 data, while 400 million obese and 1.4 billion overweight individuals live in the world, in 2015, this number has reached 700 million in obesity and 2.3 billion in overweight individuals.
It is stated by the European Regional Office of the World Health Organization that obesity affects 30-80% of adults in the European Region and that about 20% of children are overweight and one third of them are obese.
