The Atlantic reports that the amount of fuel we're using is on the rise as well, as heavy occupants need more fuel to get from Point A to *insert drive-thru joke here*. A 2006 study shows that Americans weigh so much more than they did in 1960 that we're using up an additional billion gallons of petrol every year.
That's about $4 billion a year at today's gas prices, and nearly one percent of overall fuel usage. And that was back in 2006 – as we continue to plump up, the dollars continue to pile up. Inside Line reports that each pound we gain as a population adds up to another $39 million. It's too bad we can't get stop/start tech for our appetites.
