Recession Was Biggest 'Competitor': Weight Watchers CEO

Coming off a year when its stock was up 25 percent, Weight Watchers Intenational CEO and President David Kirchoff told CNBC Monday that the company’s biggest competitor has been the recession.

“We’ve been doing comparatively well for a number of different reasons, not the least of which people [is] have been stressed out for the last two years, and now they find themselves waking up with sort of a hangover going through the last 24 months,” said Kirchoff.

"Frankly, the biggest competitor we've seen for the past two years has been the recession."

Kirchoff, who touted the company's new program and new spokeswoman — actress and singer Jennifer Hudson — also said that measuring the company’s return on investment (ROI) is relatively simple.

“We look at a cost-per-enrollment in terms of marketing costs, and we have certain bogeys that we try to perform against," he added. "We tend to moderate or spend that way. Frankly, enrollment has got to pay for itself right away.”
