"You can record everything you eat and the exercise you do using our huge food and exercise database, and then track your weight over time. Our personal profiling feature tells you exactly how many calories you need every day to lose, gain or maintain your ideal body weight."
This is great diet management software. Based on a series of questions, it determines what your daily calorie intake should be to meet your goals. It has a 7 day free trial, but it would be $45 well spent if you bought it. - Mark
