Don’t diet just yet

What would you do with a database of the weights, measurements and life histories of fourteen thousand people? Economic historian Marco Sunder used them to relate life expectancy to Body Mass Index. He reached the surprising conclusion that slightly “overweight” people lived longer.

Nobody’s implying that healthy eating and regular exercise are bad for you. All the advice is that these are worth doing for good reasons but what Sunder found, and was borne out by subsequent medical research, was that people dieting excessively to bring their bodies into the “normal” range were decreasing their life expectancies.

This is one of many intriguing, succinct and occasionally odd economic ideas in “Economics 2.0: What the best minds in Economics can teach you about business and life,” a book released this year by economics journalists Norbert Häring and Olef Storbeck. Other topics they explore include The Economics of Beauty, Why Economists love Sports, How Bad Will the Financial Crisis Get and why Europeans were a great deal shorter in the 17th Century.

    Perhaps the ‘slightly “overweight”’ should not be categorised as such…

    Shades of The Undercover Economist about this entry! Not that I’m over weight but after realizing I’m eating too much of an acid diet decided that eating more healthily is in order.

    I love economics! If only I felt that way at university…

    Its surprising that the slightly overweight live longer as the media would have us believe otherwise …
