Diet choices, yes, but much of it cultural. When the anorexic look, think of the model Kate Moss with the two inch in diameter arms, when that look started, black women did not ever comply. black men like big women, my goodness, they are padding their behinds to stick out! In a lot of cultures, being fat was a sign of wealth. All you have to do is stick some buckets of fried chicken, starches, soda, mac and cheese, corn bread, etc into an already thick frame, getting pregnant and add that weight on. Curvy is desired by their men, I remember a song in the seventies, Skinny Legs and All, I think by Otis Redding, I love you skinny legs and all, it went. Meaning, thin was not in. There were two big black nurses that supervised the 2nd shift at a nursing home I worked in, the two of them could not walk side by side in the hallway. Its not Trump, wow,,,, what a stretch. "I like big butts and I cannot lie". Another example. How you gonna make a baby to grow up to be a lineman if your petite? I suppose that was a huge racist comment, but, hey, who has the worst diabetic stats?
