You find a new Duke study that obesity rises with calories, not sofa time

While many experts have provided that high obesity rates are due to lower physical activity when societies become more industrial, the results show that people in the wealthiest countries spend the same – or even more – energy daily. In an article recently published in PNAS, Duke researchers instead indicate a high caloric as the primary driver, indicating that the diet instead of inactivity plays the biggest role in the global obesity crisis.

“Despite decades of trying to understand the radical causes of the obesity crisis in the economically advanced countries, public health instructions are still stuck with uncertainty regarding the relative importance of the diet and physical activity. This great, international and cooperative effort allows us to test these competing ideas.” In the Department of Evolutionary Anthropology.

The researchers analyzed thousands of daily energy spending measurements, body fat and body mass index (BMI) from adults between the ages of 18 and 60 years in 34 populations that extend on six continents. More than 4,200 people from adults covered in the study came from a wide range of lifestyles and economies, including the mosque of the hunter, sponsors, agriculture and industrial. To increase the classification of the manufacturing level, they also merged data from the United Nations Human Development Index (HDI) to integrate age, prosperity and education standards.

“While we saw a marginal decrease in the total modified energy spending according to size with economic development, the differences in the total energy expenses showed only a small part of the increase in the body fat that accompanies development. This indicates that other factors, such as food changes, are the ones that are due to the fat that we see with the increase in fat in the fat that we want before to advance in fat.

The researchers hope that the study will help clarify public health messages and strategies to address the obesity crisis and explain that the results do not mean that the efforts made to enhance physical activity should be reduced. Instead, the data supports consensus emerging that both diet and exercise must be determined. “The diet and physical activity should be seen as essential and supplementary, and it is not possible to switch,” the study is observed. They will then work to determine the aspects of the diet in developed countries that are more responsible for high obesity.
