Americans would become even fatter

Over the next two decades, the number of obese people in the U.S. will be increasing; at least that is what scientists of Duke University (USA) say.

It is expected that 42% of American population will be obese by 2030.

  • It means that in the nearest future, about 32 million people will become overweight.

In the next twenty years, the percentage of morbidly obese people will increase from 5% to 11%. Nowadays, about 34% adult Americans and 17% American children are already diagnosed obesity.

During the study, the specialists identified the variables, which help to predict obesity, including the changes of demographic situation, prices on healthy food and fast food, as well as the number of fast food restaurants. Later, they have modeled the way the changes of these indices can affect the obesity degree in the country.

The forecasts were presented on May 7, on the “Weight of nation” conference, conducted in Washington by Centers for Disease Control and Prevention.

Lately, it has been found that a short or poor sleep is associated with the growing risk of obesity due to the appetite disorder, causing the consumption of excess calories. The lack of sleep affects the release of ghrelin – a hormone, which increases the appetite, as well as leptin, sending signals of satiety to the brain. As a result, people start eating larger amounts of food but never compensate the energy expenditures.
