The Recording Diet

I'm not sure if this type of diet (trial to reduce weight) is known even in foreign countries, but this method is famous in Japan, originally introduced by Mr. Toshio Okada, a commentator for modern Japanese culture, Otaku. This does not need any special drug, food stuff, or equipments. You need only a notebook or small memo pad and a pen.
You can start this method by recording everything (very strictly) you ate, on the notebook. Try it for two week or so. You can loose 2-3 kg easily. This is just a beginning or an approach. Then you start to sum the calories of all stuff you ate. These are bit tedious, but you can find such calorie values by google search quite easily. After a week or two, you will loose additional 1-2 kg.
Then you start your actual performance. Everyday, you calculate your sum of the calories and keep the sum around 1500 kcal, perhaps you have to restrict some foods or snacks and sweets between meals. But what you have to care is only the daily calorie value. You do not care what kind of nutritional elements you should take. Just mind calorie. Your weight will decrease by 1 kg a week. This exactly happened to me. Do not restrict the food too much. Take it easy.
I tried this method last year, from just a year before, and continued for 6 month, resulting in loss of 18 kg (86 kg to 68 kg).
The chart below is a record of that progress.
(Blue plot shows weight in Kg, left Y-axis; Red plot shows fat content in %, and the yellow indicated total fat weight in Kg. X-axsis is dates starting from May 10, 2008 to Oct 10. The gap of the plots in the middle, missing data, was because of my travel to Oxford, UK, where the scales were not available.)
