I read an interesting article today that said that keeping a food journal can increase your weight loss by up to 50%.  I found this very interesting because I kept a food journal for a few months and found that it did not help me to loose weight.  I have been thinking about starting back up with the food journal with the twist of writing down what I eat before I eat it.  The premise for this is, if you are about to overeat and you actually take the time to write down how many cookies you are about to put in your mouth you might think twice about it. 

Do you have any experience with a food journal?  If so what effect would you say it has had on your weight loss?  Do you have any tips for making the journal work instead of having it just create more work?
