Record your weight everyday, but take a moving average, basically the average of the last N days. That way, you will mitigate the random fluctuations. There might be better estimators of course (Kalman filter anyone?), but I believe they would be overkill. This book was recommended on HN in a diet related article: The Hacker's Diet, http://www.fourmilab.ch/hackdiet/www/hackdiet.html http://www.fourmilab.ch/hackdiet/www/hackdiet.html It's written by the founder of AutoCAD.
