Matt Richtel and Andrew Jacobs, The New York Times:

The latest data from the National Health and Nutrition Examination Survey comes at a time when the food industry is pushing back against stronger public health measures aimed at combating obesity.

In recent NAFTA negotiations, the Trump administration has proposed rules favored by major food companies that would limit the ability of the United States, Mexico and Canada to require prominent labels on packaged foods warning about the health risks of foods high in sugar and fat.

While the latest survey data doesn’t explain why Americans continue to get heavier, nutritionists and other experts cite lifestyle, genetics, and, most importantly, a poor diet as factors. Fast food sales in the United States rose 22.7 percent from 2012 to 2017, according to Euromonitor, while packaged food sales rose 8.8 percent.
