Four months ago I started a diet, as my weight had gone above my comfort zone (77kg, when my optimal weight is of about 70kg). I basically implemented a regime (which has worked in the past) of about 1300 calories a day, cutting mostly on extras (desserts, snacks, alcohol) and bread, and just eating a bit less of everything.
My original target was to reach 70kg, but I got greed as I saw that I was losing weight without too much effort, and brought my weight down to below 68kg. I must say I feel great being actually underweight... Now I have suspended the diet as December will be a month of intense travel for me; I am back from four days in Granada, Spain, where I gave a seminar in the theory department, and next Monday I am leaving to the US for two weeks there. When I travel I cannot control my diet as I would like to, so it's better to keep the diet on hold.

You can check the progress of my weight in the chart below. On the abscissa are days since October 2002 - when I started to record my weight. The interpolation line is just a 7-day average. The scale of the weight loss amounts to about 60 grams per day.
