Okay, I went surfing on the web (surprised?) and came across dietpower. You can get a download for seven days--free. So, if you are wondering if it is for you, then try it. I then bought the installation for $50. You enter your food in and it figures your calories and the whole nine yards. This is the really great part--you enter your activities in, like walking, weightlifting, whatever, and it figures out how many calories you have burned for that activity. It then subtracts that amount of calories for the food you have eaten. It takes a couple of weeks, but as long as you are faithful, then it will start figuring how many calories your metabolism is using and it will figure how many calories that you need to eat in order to lose weight. I was using it faithfully, until my husband and I both lost our jobs the end of August and my world got turned upside down. I really haven't gotten back to using it, yet. The one downside that I have found is that we don't have our computer booted up all of the time, so every time I eat something, I have to go boot it up to record it. If you want something similar that doesn't cost anything, try www.fitday.com
Theirs is free and it is easy to use. I didn't come across it until just a few days ago. I emailed it to several of my friends and they were very impressed with it. Let me know what you think. Good luck!
