I use an application I downloaded on my IPod called Lean Me. The application has thousands of foods in the data base. If a food is not in the database you can add it. The program tracks my weight, measurements, BMI and all food and liquid intake. This is not your typical $1.99 application. In fact, I think it cost $14.99 and worth much more! It is so easy to use and I don't have to remember to carry a log with me I just drop my IPod in my purse and I'm go to go. I love that the program shows my weight loss graphically and reports on nutrition intake for the day, past 7 days and a 30 day average. Really helps me manage myself!!!
