A little diet with that chocolate?

VEVEY, Switzerland — In a move that recognizes the modern world’s twin obsessions — indulgence and guilt — chocolate maker Nestle said Monday it would purchase weight loss product maker Jenny Craig Inc. for $600 million.

The acquisition follows Nestle S.A.’s purchase for around $670 million last month of Uncle Tobys, an Australian maker of nutritional cereals and snacks, and is part of the company’s “continuing commitment to nutrition, health and wellness,” the Swiss company said in a statement.

While best known for its namesake chocolates, Nestle is the world’s largest food and drinks company, making baby formulas, nutrition foods such as PowerBar, drinks to aid weight loss and the Lean Cuisine line. The company’s purchase of Jenny Craig follows the lead of consumer products company Unilever, which bought both Ben & Jerry’s ice cream and Slim Fast in 2000.

Weight management will become a new business within Nestle’s nutrition unit and will reinforce its U.S. presence, the company said.

“With this strategic acquisition, the group takes another important step in its transformation process into a nutrition, health and wellness company,” said Nestle Chairman and Chief Executive Peter Brabeck-Letmathe.

“The rise of obesity and the resulting metabolic disorders, such as diabetes and cardiovascular disease, is a major public health concern, not only in the USA but also the world over,” Brabeck-Letmathe said.

Jenny Craig, which has more than 3,000 employees and more than 600 centers in the U.S., Canada, Australia and New Zealand, generated sales of more than $400 million in the past 12 months and achieved double-digit internal growth.

Nestle is buying Jenny Craig from two private equity groups, ACI Capital and MidOcean Partners.
