Over past three decades. obesity rates increased fourfold among children and doubled among adults
More than 1 billion people worldwide are now living with obesity, with rates among children increasing fourfold across a 32-year period, according to new research.
Analysis of the weight and height measurements of over 220 million people from more than 190 countries shows how body mass index (BMI) changed across the world between 1990 and 2022.
Approximately 1,500 researchers contributed to the study by the NCD Risk Factor Collaboration with the World Health Organization (WHO). Published in the Lancet, it found that over the period obesity rates increased fourfold among children, and doubled among adults.
If more countries treated obesity as the disease it is, we might learn the real causes, and maybe have some effective treatments. All the noninvasive treatments don’t work long term for the vast majority from what I have read.
On the less proven track, there are hypotheses that obesity may be driven by bacteria that colinize the gut and impact brain function to train a person to be addicted to certain foods. Still far from proven, but if the funding was there we might know one way or the other.
