The future of dieting

Economist Ed Glaeser, a trim man, is a vigorous partisan of the Atkins Diet. Nonetheless he argues that McDonald’s brings social benefits, not social costs:

Glaeser’s rationale for suggesting that convenience foods are a social good is that, to judge from consumer behavior in the marketplace, people seem to prefer saving time to being thinner. And in economics, by and large, getting what you want is a good thing. Glaeser notes that until relatively recently, cheaper food (in terms of money as well as time) made us taller and healthier. Only in the past 25 years or so have diminishing returns set in.

Now that less is more when it comes to increased calorie intake, Glaeser expects the marketplace to correct the excesses he attributes to self-control problems. For one thing, food technology can’t advance much farther, “short of direct injection,” whereas weight-loss technology is only in its infancy, with vast room to grow. Glaeser can understand the need for regulation in the schools, or if food companies are misleading people. But he says: “I don’t think anybody ate at McDonald’s and thought it was good for them. I take a dim view of these lawsuits.”
