Losing weight is one of the most popular New Year's resolutions -- and one of the most easily and often broken.
It's not surprising, given how difficult it can be to lose weight at any time of the year, let alone under a set deadline like January 1. "When making our resolutions, we think 'big picture' and focus on the long-term," Alexander Chernev, an associate professor of marketing at Northwestern’s Kellogg School of Management, told The Wall Street Journal. "Then life takes over. When given the choice between the immediate gratification of indulging now and the future gratification of losing weight, people tend to be myopic and favor the short term."
