Personal Trainer One is a comprehensive food, exercise, and weight management software package. A food journal keeps track of whatever you eat, automatically calculating and analyzing nutritional information in a variety of formats. An exercise journal records physical activity for convenient reference. Separate, detailed support exists for cardiovascular/sport and weight-lifting activities. Other resources include a BMI calculator, caloric requirement estimator, and a recipe book that automatically generates a standard nutritional label for virtually any dish. A weight loss consultant is integrated with other program features and can figure how many calories one can eat and still meet a desired weight on schedule. This update adds over 500 brand name fast foods to the built-in U.S.D.A. database, and improved support for user entered foods and exercises. P.T.O. has a flexible, user-friendly interface, and allows for multiple user profiles on one PC.
