My experience is the same. There were no more than five fat kids in my elementary school. Overweight kids were so unusual back then. I remember the school nurse weighing us once a year, weight and height measurement. One of my friends was a bit chubby (not fat), and the nurse sent a note home to her parents, along with a diet for her to follow. I live in an area where people are well off and well educated. Very few fat kids or adults. One town over and it seems nearly everyone is overweight.
