I, too, weigh daily. I track it on Fitday, that way I can see trends, and look for where I had good losses and bad gains and see what I ate and try to repeat it (or avoid where the case may be). I found that I personally have to stay away from the LC Ice creams because they cause such grief -- a six pound gain in a week. Since quitting the ice cream, I have lose 8.4 pounds. I wouldn't have known where and when to look had I only been weighing-in every month, or week for that matter. I just like to know where I stand.
