I hate logging my food because I'd rather be in denial about it all. ;) But I am committed to doing it this week at least. I am using the MyFitnessPal app. I definitely do best with an app and I love that it has a scanner to just scan the barcodes on all kinds of stuff. It takes away excuses because it is so quick and easy. Other health related apps I use are Runkeeper, Eight Glasses a Day, and Track My Weight. I also love the P90X app for tracking my P90X workouts and weight/rep amounts.
