I recently got an app-supporting phone that has access to the android app market, and I found an app called Calorie Counter (powered by the FatSecret website). It's totally free, and it allows you to record what you've eaten for the day, gives you your totals for calories, fat, carbs and sugars, your percentage of calories used up (based on a daily limit that either you allow the app to calculate based on your weight, height and activity level or one that you set yourself) and it has virtually every branded product you can think of - and a barcode scanner. It's amazing. It's fun to tinker with, and does away with the boring pen-and-paper food diary. I've used it all week faithfully, and it must have kept me on the straight and narrow - I lost 2 lbs this week! I NEVER lose 2lbs in one week! Try it, it's great and it's free!!
... lmao, that totally sounded like an advert. XD
