In 2000, the American Journal of Medicine published a study that found Weight Watchers effective. Research showed that participating in the Weight Watchers program yields better results than going it alone. The study followed 65 men and 358 women for two years as they tried to lose weight with either a self-help program or the Weight Watchers program.
The Self-Help Program
Members of the self-help group met with a nutritionist in the first and 12th weeks. During counseling sessions, they received hard copies of information about healthy diet and exercise habits. In addition, self-helpers were told about other sources of weight-loss advice such as library materials, Web sites and phone hotlines. Once they were given the information, though, they were on their own to put it to use.
