Economics of losing weight and other New Year’s Resolutions

One of the most popular New Year’s Resolutions is losing weight. While some would like to shed off the few extra pounds gained during the holiday season, obesity is an increasing issue throughout the world. According to the World Health Organization, more than 2.1 billion people, nearly a third of the global population, are obese.

McKinsey Global Institute has calculated, in a study published in November, that “obesity is responsible for about 5 percent of all deaths a year worldwide, and its global economic impact amounts to roughly $2 trillion annually, or 2.8 percent of global GDP – nearly equivalent to the global impact of smoking or of armed violence, war and terrorism.”

Yet the European Court of Justice, the EU’s highest court, recently ruled that while not a disability in itself, obesity could be considered one if it caused physical, mental or psychological problems that hindered a person from doing work in the same way as her colleagues. As an economist, I feel that giving people legal grounds to feel righteous about their obesity is actually a disincentive for losing weight.

In the U.S., obesity affects one-third of Americans and costs companies $73 billion a year, according to researchers from Duke University. Firms have already moved beyond standard approaches, such as vending machines offering healthy food and subsidies on gym memberships, and are now after more innovative solutions. While some are handing out fitness trackers, others are covering weight-loss surgeries and drugs, as well as counseling.
