I sometimes wonder about all the people telling other people to eat more calories. It seems to be extremely individual. Apply what worked for you to everyone else and assuming it'll work for them is a mistake.

Personally, I have to watch my calories on Atkins now. People make such a big deal out of it, as if its some horrible task that would rob them of hours a day. I got the Fitday for PC and started logging everything I ate, didn't take long. Eventually as my catalogue of customized foods built up it gets faster and faster to the point where I could log a whole day in about 5 minutes. After awhile my body got used to eating 1200-1400 calories per day and I don't really need to log it any longer. Except when I stall, then I find logging and weighing helps me get back on track. Sometimes those 1 ounces of nuts or cheese start becoming larger!

Its also useful for making sure you're not shortchanging yourself nutritionally.
