I use this great program called Diet Power... i'm not crazy about the name... it's a fitness and nutrition program... and i love it. I found it about two years ago i guess. You plug in what you eat and what exercise you do and it figures out the calories in and the calories burned. In addition it is constantly calculating your metabolic rate based on the information you are giving it everyday. Then it gives you the amt of calories you can eat that day based on your current metabolic rate so that you will reach your goal weight by the date you set.
The other thing i really like about it is the fact it calculates how much of each vitamin you've consumed as well as minerals, water, fiber, carbs, protein, etc etc. It is just so kewl if you really want to make sure you are getting everything you should be from your diet even if you don't want to lose weight. The food logs are huge so they have just about anything you could imagine eating so you don't have to guess or go to great lengths to find the food info and enter it. Well enough about that... as you can tell i think it's the best fitness program out there and well worth the money to buy it.
Well here's the starting screen of DP... this is another part i think is so kewl... with this you can see exactly what you're doing and where you're going. Some info has been obliterated to protect the innocent and the fat... which in this case is me... lol.
