How pitiful. At some very early age, she must have given up. In our culture, fat is ugly; in other cultures, not so much. My husband is native American. Not much fat shaming, there, in most tribes. I hope this poor woman gave her heart to the Lord before she passed.
That's because reservation life has got most of them eating white man's food--high fat, high carbohydrates. Under the original native culture they were more hunter-gatherer types and had higher protein diets.
I lived with Indians in Canada for two years and it was common for young Indian children to come into the house and scoop a handful of lard from the kitchen, sprinkle a little salt on it and just eat it straight. That can't be good for you.
