The power of money. Obese people offered a financial reward for every pound lost shed more weight during a 16 week trial than those given diet advice. That’s not all. Previous studies show that smokers and cocaine addicts can be weaned off their habits by paying them to stay drug-free. Kids in developing countries actually attend school more when their parents are paid for it. A study currently underway in New York is assessing whether cash incentives motivate parents to send their kids for regular health check ups.
The diet study from U Penn found that many participants put weight on again after the program ended. The authors suggest long lasting results need long lasting payments. The paper appears in the Journal of the American Medical Association.
So what would thinner people buy for the planet? How about fewer greenhouse gas emissions. And what else might we buy for the common good? Peace? Rational thinking? If all it takes is money and we’re already running the presses overtime, why not print some more?
