Entering your food

Go to diary page. Enter banana in box. To the right you should see a box that verifies you are entering a banana. Choose banana according to the size you want to eat. Enter .05 because that will indicate half of a banana. Hope that helps.

If it is in your means, invest in a good scale. You can weigh the exact portions you eat for situations like this and get a better idea of the calories. Some people think it is too much work, but I prefer getting exact data and tracking it has given me great results.
