This new study is generating a lot of "controversy" as they like to call it in mainstream media. By controversy, what is really meant is the falsification of the calories in/out postulate that is so popular among medical professionals and dieticians.
Here's why kids are still getting more obese
"...According to a 2015 New York Times analysis of government and private-sector data, the number of calories consumed annually by the average US child declined 9 percent between 2004 and 2013. And yet, researchers from Duke and Wake Forest have found that trend has not improved the child obesity situation. Using body mass index data from the National Health Examination Survey, which tracks randomly selected households with health exams and surveys every two years, the researchers calculated moderate (class 1), mid-level (class 2) and extreme (class 3) obesity rates among kids aged 2 to 19. Here's what they found, from a paper they published in the peer-reviewed journal Obesity."
