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 recipe book that automatically generates a standard nutritional label for virtually any dish. A weight loss consultant is integrated with other program features and figures how many calories one can eat and still meet a desired weight on schedule. Many brand name fast foods are included, and new foods (or exercises) can readily be added. This version includes routine USDA database updates, and the free 'DietWars' screensaver. P.T.O. has a flexible, user-friendly interface, and allows for multiple user profiles on one PC.
