The Fuel Cost of Obesity 285

thecarchik writes "America loves to complain about gas mileage and the cost of gasoline. As it turns out, part of the problem is us. How much does it really matter? A study by the Centers for Disease Control and Prevention found a 1.1 percent increase in self-reported obesity, which translates into extra weight that your vehicle has to haul around. The study estimates that 1 billion extra gallons of fuel were needed to compensate for passenger weight gained between 1960 and 2002."

    One key finding was that almost 1 billion gallons of gasoline per year can be attributed to passenger weight gain in non-commercial vehicles between 1960 and 2002--this translates to .7 percent of the total fuel used by passenger vehicles annually.

    So they found it had nearly nothing to do with it. Spiffy.

        There was a study a while back which said that if people could purchase junk food when they purchased their groceries or gas or whatever other reason they needed to be at a store, we could cut something like 15% of our annual fuel usage. Of course I can't find a link to the article on it, but it was about consolidating trips to the store to save on fuel expenses.

        But if the obese people die much earlier they might still use up less energy and resources overall.

        e.g. Instead of dying at 80 they die at 60.

        I believe by the time most people hit 70 they start to consume more resources and wealth than they produce.

        For similar reasons that's why smoking isn't so bad (assuming you collect hefty tobacco taxes) :).

      So it was actually 1 billion gallons per year, not total. Seems like the blog words it poorly and that they're really saying that if we were all the same weight as we were in 1960, we would have used 1 billion gallons less fuel last year than we actually did. But that is still only a 0.7% increase in yearly consumption.

      More fun is this observation:

      One other result of the obesity problem is the increase risk of crashes as noted in a recent study and that is also due to the fact that obese drivers are less likely to buckle up because seat belts may not fit properly.

      So basically, fat people are looking for Darwin Awards. Now just make sure they are all distracted on their giant phones, and problem solved.

      Of course, you can only make that argument because somebody bothered to compute how much human weight affects fuel consumption. It is wrong to claim that a study was unjustified because it shows that further concern over some issue is unnecessary.

      Every time I read a comment like yours I realise that people don't get it. There's a finite number of drops in the bucket. Removing one alone does nothing appreciable. But if you start removing many of these tiny drops pretty soon you'll find the bucket is starting to empty. This isn't a 1B saving over 20 years. This is an ADDITIONAL 1B saving over 20 years.

      Though admittedly fat people die younger, and may have difficulty breeding so that's probably good for the environment.
