Fat-E: The new Pixar movie goes out of its way to equate obesity with environmental collapse. by Daniel Engber, posted at Slate.com.

An excerpt:

…the metaphor only works if you believe familiar myths about the overweight: They’re weak-willed, indolent, and stupid. Sure enough, that’s how Pixar depicts the future of humanity. The people in Wall-E drink “cupcakes-in-a-cup,” they never exercise, and if they happen to fall off their hovering chairs, they thrash around like babies until a robot helps them up. They watch TV all day long and can barely read.

It ought to go without saying that this stereotype of the “obese lifestyle” is simply false. How fat you are has a lot more to do with your genes than with your behavior. As much as 80 percent of the variation in human body weight can be explained by differences in our DNA. (Your height is similarly heritable.) That is to say, it may not matter that much whether you eat salads or drink “cupcakes-in-a-cup,” whether you bike everywhere or fly around in a Barcalounger. If you have a propensity to become obese, there’s only so much that can be done about it.

That’s not to say that our circumstances can’t lead us to gain weight. But there’s little evidence that overeating causes obesity on an individual level and no real reason to think that anyone can lose a lot of weight by dieting. (Most of us fluctuate around a natural “set point.”) We also know that children who watch a lot of television are no less active than other kids and that pediatric obesity rates are not the direct result of high-fat diets.

I haven’t seen Wall-E yet, but this is the second exploration of the fat future shown in the film that I’ve heard and read. (Kevin Smith discussed it at length in his last SModcast, as the cupcake-in-a-cup future is his ideal.) I include it here in part because Engber cites several other articles that make points that I’ve often had to remind my dear husband about, particularly in a recent dark time in our relationship.
