Study Shows Greater Initial Weight Loss with Jenny Craig Program Compared to Self-Help Counseling

Balanced Approach Proves Positive for Weight Loss and a Healthier Heart

Carlsbad, Calif. (Nov. 17 2005) - According to recent findings presented at the 2005 North American Association for the Study of Obesity (NAASO) Annual Scientific Meeting, the Jenny Craig program demonstrated significantly greater initial weight loss than self-help plus brief diet counseling. Preliminary results showed that Jenny Craig subjects lost approximately 8 percentof their initial weight at 6 months, as compared to the less than 1 percent of initial weight loss experienced by those who had usual care alone.

Additionally, the study found that the Jenny Craig program not only promotes successful weight loss, it also provides heart health benefits, due to a significant reduction in triglycerides and improved cardiopulmonary fitness. As indicated by an increase in levels of blood carotenoids, the study suggests that Jenny Craig subjects also increased their intake of fruits and vegetables, which potentially offers both nutritional and health benefits.

"This is the first time the core components of the Jenny Craig program - nutritionally balanced portion control, exercise and individualized, motivation-based counseling - have been studied in this combination," says Cheryl L. Rock, PhD, RD, Professor of Family & Preventive Medicine, University of California, San Diego. "These interim results show that people can be more successful with this multifaceted, structured approach."

Nearly 100 million adults are overweight or obese in the United States, which can lead to serious diseases such as, diabetes, heart disease, hypertension and certain types of cancer. A five to ten percent reduction in body weight reduces the risk for several of these diseases.

"We have thousands of documented success stories with the Jenny Craig program and are pleased to see it validated in a clinical trial as well," says Patti Larchet, CEO of Jenny Craig. "Successful weight loss requires a comprehensive approach. Jenny Craig offers a complete package and we have the tools in place to help our Clients meet their goals."

About the Trial

The 24-week trial titled, "Randomized Trial of A Multifaceted Commercial Weight Loss Program," studied people who were 18 years and older and at least 33 pounds over ideal weight, with BMIs greater than 25. Subjects were stratified by BMI and age, and randomly assigned to the Jenny Craig weight loss program or the usual care group. The Jenny Craig subjects received all Jenny Craig weight loss program activities, materials and food as needed, free of charge. The usual care group received standard weight loss consultations with a registered dietitian, free of charge, at randomization and six months. Key findings include an average weight loss of 7.8 percent and a significant reduction in triglycerides over a six-month period in the Jenny Craig group, compared to a 0.3 percent weight loss in the control group and no change in triglycerides.

These data follow an evaluation last year from The Cooper Institute indicating that Jenny Craig program effectiveness meets or exceeds rates of weight loss achieved with intense behavioral or medical treatments, citing overall weight losses of 8 percent, 12 percent and 15 percent, based on ninety percent attendance of weekly consultations for 10, 26 and 52 weeks of active participation in the program.
