I look back as a kid growing up in the mid 70's and I recall most of the others in School etc. were all skinny like I was. There was an occasional overweight kid but nothing like today. We didn't starve but our diet and exercise were way different than today. Also to make things worst we have CORN. Everyone should watch this documentary "KING CORN", it's an eye opener.
