Obesity is now the most common form of malnutrition in most countries, with the rates rising in all categories of men, women, children and adolescents since 1990. Obesity rates in adult men have nearly tripled since 1990, with obesity rates in woman doubling in that time. The rates of obesity in children and adolescents quadrupled in that time frame, as well. As of 2022, nearly 880 million adults and nearly 160 million children were living with obesity.
