If this is going to be a discussion on health (rather than on body type), then it needs to be said that an overweight person with an active lifestyle is more healthy than a person of ideal weight who doesn't exercise.
Let's shell a little blame where it belongs: On everyone. That might seem like a "no solution" kind of answer, but I can't believe that a specific demographic is responsible for such a broad problem. Every type of man and woman plays their part in the issue, whether they do so with their libido, their greed, their ideals or their personal insecurities.
That aside, I noticed you used the word "pop" in your post. You aren't from Wisconsin, are you?
The term soda is used all along the North East coast. NYC, Boston, etc.
They start calling it pop somewhere in eastern Pennsylvania (I know it is pop in Pittsburgh).
How far north and east it goes from there I do not know.
