Successful diet

Finally I've reduced my weight from 73.8kg to 64.8kg in the last four months. It's a great joy for me to complete this seemingly imposssible task. It seemed to be a long way to go when I started this plan. But a bit more attentions to daily meal and a change of my weight led me to the goal that I set last year.
Before this daily task, I read a book on how to reduce weight. The author recommended the way to write down the total amount of calories you take everyday. It encourages us to know how meaninglsess foods we are eating. I followed this method by using Excel files. Gradually I found it interesting because I noticed that the change of my weight responded to the amount of foods and phisical exercises.
