With all my previous attempts years back, calorie counting was the bane of my existence. I used a rather 'traditional' method of pen and paper with those little books loaded with caloric information. Yeah, that lasted about a week max each time.
Now, however, I use the Livestrong application on my iPhone and have been successfully calorie counting for three months now. The thing I like about the app is that it has A LOT of things you can search for--including food in restaurants. Also, if you go online to their website, you can enter recipes of meals you've cooked and it will calculate the calories for you. Overall, my boyfriend and I have been very please with the app and it has helped us tremendously keep on top of counting our calories.
