Weight Watchers was recognized as the Best diet plan for weight loss and best industrial diet plan in the first U.S. report and world report ratings.
The result was finalized by a panel of 22 leading, independent scientific experts after conducting a 6-month assessment of 20 diets and diet programs.
"This acknowledgment by U.S. News and World Report underscores what numerous clinical studies have already shown about the efficacy of our approach to weight loss," said David Kirchhoff, president and chief executive officer, Weight Watchers International, Inc.
The Weight Watchers PointsPlus program emphasizes the need for a healthful, balanced diet made up of nutrient-dense foods including fresh fruit and vegetables, lean protein and whole grains - essential nutrients to help consumers achieve healthy, long-term weight loss.
The Weight Watchers program is scientifically proven to reduce the risk of obesity-related conditions such as type 2 diabetes, heart disease, stroke, high blood pressure and some types of cancer.
"One of the reasons our program is successful is because it helps guide people to delicious, nutrient-rich foods. It's a simple and affordable answer to achieving a healthy weight and living a healthier life," Kirchhoff said.
The result has been published online.
