For those who are interested in tracking their calories in and calories out, you might consider a computer program called Life Form http://www.fitnesoft.com/. You enter a bunch of general information about yourself (height, weight, activity level, etc). It then calculates your basal metabolic rate.

Then each day you enter everything you eat. It has a data base with the nutritional values of many foods. And you can add items to the data base. You also enter how much you work out each day. You can either enter: 2 hours of cycling at a “moderate rate” or you can enter 2 hours of cycling at a heart rate of 155. Then you can view the info on lots of different charts and graphs. It’s pretty interesting to see it in writing.

I’ve had the program for a while and I use it off and on. I usually use it when I’m training for something or if I’m trying to drop a few pounds.
