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.
