It is not just that humans have become heavier in the last decades, but also some species of animals, including completely wild species.
The problem of obesity isn’t confined to just humans. A new study finds increased rates of obesity in mammals ranging from feral rats and mice to domestic pets and laboratory primates.Americans have grown increasingly heavier, with the average body mass index or BMI, a measure of height and weight that estimates fatness increasing from about 25 in the early 1960s to around 28 in 2002, according to the Centers for Disease Control. The CDC considers adults with BMIs between 25 and 29.9 to be overweight.Increasingly caloric diets and lack of exercise are usually cited as major causes of human obesity. These factors undoubtedly play a role in Americans’ expanding waistlines, said lead study researcher David Allison of the University of Alabama, Birmingham.
