The Journal's interview with Weight Watchers International CEO, David Kirchhoff. Weight Watcher's strategies focus on increasing its online business and getting males to join Weight Watchers. According to Kirchhoff it has 1.4 million people, 90% of whom are women, attending meetings each week all over the world. Online business is surging, with an average of 1.8 million additional subscribers for the first 3 quarters of 2011. In the first 3 quarters of 2011 the online business showed gains of 70%. Estimates are for the online business to generate $400 million in revenues and $200 million in operating income in 2011. Today 65% of the business is in the U.S. and a large part of the rest is in Europe. Kirchhoff sees new opportunities in China, where poor lifestyles- the use of the internet instead of being outdoors, and the increased access to all kinds of food- is creating a surge in obesity.
