When I went to high school in the 80s I only remember there being one huge girl and one huge guy in our grade.  He was called Tank and I forget what we called her, but she knew her place and was always taking diet pills and certainly didn't think of   4000  herself as curvy and beautiful.  Plus, loved that show, when I watched it, I never thought that girl looked anorexic, I just thought that Winona Ryder looked old lol.
