You're on to a very good idea. I've been keeping a daily food log for three+ years. I initially started it as a way to track what foods were causing me issues. It helped me pinpoint which foods to eliminate. Once I figured that out, I kept up my food diary and it helped me lose the pounds I'd packed on because of my stomach/allergy problems. Now I still use it as a weight maintenance tool and have kept those awful 10 pounds off for about a year. I hope you have similar success. Actually, if you stick with it, I'm sure you will. But don't forget to add in some exercise 3-5 days a week. That will help you achieve success and maintain your weight afterwards.
