WHO: More than 1 billion people in the world are obese

 That is in the estimates revised by a group of international researchers of the World Health Organization (WHO). Obesity is widespread and has become more common than being underweight in many countries, including many low- and middle-income countries that previously suffered from malnutrition. "A large number of people live with extreme obesity," said the lead author of an article published in The Lancet Alkhamisi and a lecturer at Imperial University London. The results, which are considered among independent research estimates, have included data from more than 220 million people in more than 190 countries. This includes approximately 880 million adults and 159 million children, based on 2022 data. International scientists say there is an urgent need for major changes in the way obesity is tackled. Obesity can increase the risk of many serious health conditions, including heart disease, type 2 diabetes and several cancers. Obese people have worse memories than their thinner counterparts, a small study has shown. A study conducted on 50 people showed that being overweight was associated with "episodic memory" or the ability to recall past events.
