From the CDC:

Percent of adults aged 20 and over with obesity: 39.8% (2015-2016)

Percent of adults aged 20 and over with overweight, including obesity: 71.6%

The prevalence of obesity decreased with increasing income in women (from 45.2% to 29.7%),

but there was no difference in obesity prevalence between the lowest (31.5%) and highest (32.6%) income groups among men

To provide a little numerical context:

For the average height man (5'9"):

Overweight: ~170 pounds+ Obese: ~200 pounds+

For the average height woman (5'4")

Overweight: ~145+ Obese: ~175+

Bonus Q: considering the statistics are about even between men and women (though not when controlling for income), might one gender or the other be more affected in the dating market by heaviness?
