You beat me to it. Hispanics/Latinos and Blacks have the highest rate of obesity among the four major races/ethnicities in America. Whites are third and Asians are last. This is not a popular fact for a reason, and you will not see the liberal MSM report about it. 

ALL ADULTS - 34.9%
BLACK - 47.8%
HISPANIC-LATINO - 42.5%
WHITE - 32.6%
ASIAN - 21.7%
