If you read the fine print you'll see they're using BMI to determine if people are overweight or obese. BMI is a tragically flawed metric (https://www.medicalnewstoday.com/articles/265215.php https://www.medicalnewstoday.com/articles/265215.php) and I would approach the 70.7% figure with caution. The more compelling story in the stats is the trend showing a gradual rise from 54.9% in the period between 1988-1994 to the more current figure of 70.7% in the period between 2013-2014. I'm skeptical of the raw figures given issues with BMI but highly doubt such a massive increase came from US adults getting significantly taller or more muscular (both factors that can inflate BMI for healthy individuals).
