You are only lying to yourself if you fudge the numbers in the journal! Learning to be honest with yourself is a good point to start from. Keeping a journal of your meals and weight loss really helps you see what your habits are, and how you are progressing. I like to look back through my old journals to see how far I have come! In my journals I kept track of all the food/drink I had, their calories, my weight, and if I exercised. I filled the borders with motivational sayings, and also kept record of my measurements!
