“THURSDAY, March 31, 2016 (HealthDay News) — More people worldwide are obese than underweight, a new study found.
The researchers added that about one-fifth of adults could be obese by 2025.
The number of obese people in the world rose from 105 million in 1975 to 641 million in 2014, with obesity rates rising from 3 percent to 11 percent among men and from 6 percent to 15 percent among women, the study found.
Over the same time, the proportion of underweight people fell from 14 percent to 9 percent of men and from 15 percent to 10 percent of women, according to the study.
More than one-quarter of severely obese men and nearly one-fifth of severely obese women in the world live in the United States, the researchers said.
On average, people worldwide have become an average of 1.5 kilograms (3.3 pounds) heavier each decade. At the current pace, about 18 percent of men and 21 percent of women will be obese, and more than 6 percent of men and 9 percent of women will be severely obese by 2025, the study found.
The findings were released online on March 31 in The Lancet.
