Click here to visit the CR Society.A Calorie Restriction "CR” Diet is one in which people eat fewer calories while maintaining - and often improving - their nutrition. The CR Diet is not a weight-loss program although weight loss is usually a natural consequence. The goal of Calorie Restriction is to obtain optimal nutrition from the fewest calories. By maximizing the "nutrient density" of their food intake, calorie restrictors enjoy not only a healthier life, but anticipate a longer one as well. Several studies indicate that the CRON lifestyle can achieve both of these goals.

The Calorie Restriction with Optimal Nutrition Effects Pilot Study is a landmark study Most of the participants are members of the CR Society. These participants carefully record, track, and analyze their food intake for a wide variety of nutrients. Their goal is to optimize nutrition while restricting their calorie intake, making a record of their progress over time, to shed light on the Study’s hypothesis that specific clinical and medical laboratory tests are associated with and provide evidence for the beneficial effects of CRON. The participants will also be tracking metabolic measures to gain insights into their energy expenditure.

August 26, 2002... NutriBase Clinical Named the Official Dietary Monitoring Software for the “Calorie Restriction with Optimal Nutrition Effects Pilot Study.” Leading scientists, specializing in calorie restriction, have chosen NutriBase Clinical Nutrition and Fitness Manager as the official dietary monitoring software for the study to help unlock the secrets of lengthening vigorous life span through CRON.

According to Meredith Averill McGlothin, Communications Coordinator for the Study, "Research involving nutrition requires the most precise dietary tracking software available. This made NutriBase ® the natural choice for the CRON Effects Pilot Study."

Richard S. Lord, Ph.D., Director of Science and Education at MetaMetrix Clinical Laboratory and Testing Co-Coordinator for the Study, says "The nice thing about NutriBase is that although it's robust and flexible enough for dietitians' and nutritionists' professional use, it is also designed for individual use, which makes it a logical choice for this study. It is a powerful tool."
