Obesity is not just people: the average weight of many animals growing

Obesity - one of the most acute problems of standing at a high stage of development. It is believed that people gain weight because they can not limit itself to the high-calorie foods and sweets, but scientists say it's too simple an explanation - causes "obesity epidemic" is much more complicated than the banal gluttony, especially when you consider that in recent years all More people get fat not only, but also, for example, monkeys.



Here is how the problem in an article published in the journal «Aeon», one of the leading researchers of this phenomenon David Berrebi:

"A disturbing trend of this kind back in 2010, he told a group of researchers from the University of Alabama, led by David Ellison: In the past 20 years the animals, like people get fat rapidly.

After studying the data on changes in the average physiological indicators chimpanzees, monkeys, mice, pet dogs and cats, and rats, the researchers found that the average weight of the animal increases. For example, ten years for the Monkey "recovered" at 9% of the total body mass, and laboratory mice - 11%. Worst of all is the case with chimpanzees - the average weight of their bodies in a decade has grown by 35%. "Almost in every population that we studied, there was this law," - once said to me, surprised by such results of the study Allison.

Clearly, when fattening pets that owners feed "for slaughter", but, for example, it is unknown why the weight gain of experimental rats, food is strictly regulated. My colleagues are closely monitoring the vital functions of laboratory animals that can completely eliminate the impact of any accidental factors, but plump guinea continue with no change in their diet and activity.

If the animals gain weight together with mankind, it says that in nature there are certain processes that control the development of entire species and not depend on the habits of specific individuals ».
