There’s no doubt about it: Americans are getting heavier and heavier. But new U.S. estimates may still come as a shock — since the late 1980s and early 1990s, the average American has put on 15 or more additional pounds without getting any taller. Even 11-year-old kids aren’t immune from this weight plague, the study found. Girls are more than seven pounds heavier even though their height is the same. Boys gained an inch in height, but also packed on an additional 13.5 pounds compared to two decades ago.
