This is a good idea, but the execution is lacking. In particular, the data entry is really painful. There are two big problems: 1. I have to somehow know the calorie counts for every exercise I do and every food I eat. You should let me input the activity/food and calculate the calories. 2. I am not in front of my computer all day. In particular, when I'm exercising and eating I'm not. And that's exactly when I want to add data to a service like this. You need an iPhone app, not a web app.
