I joined myfitnesspal to help me. This is a really neat FREE site that helps you track your daily activities and nutrition. There are a few sites out that that help you with this, but I really like this one because it is FREE (of course), but also because you can customize your own foods and activities.
Another site I tried, MyCalorieCounter, only lets you customize if you upgrade to a paid membership. Also, to get your food totals, you need to upgrade as well. This, I found wasn't very helpful. The other site I used to use was FitDay, and it doesn't let you customize your activities, and it doesn't have elliptical trainer in its database. That's what I use more frequently, so I found the site wasn't meeting my needs.
I just discovered myfitnesspal yesterday, and so far I love it! It is very easy to use! It even makes counting calories kinda fun. Hee hee...
Wish me luck on my goal. I'd like to accomplish this by summer, but if it takes longer, I don't mind--as long as the pounds are shed in 2008!
