'Necropost'... wow, there is something I haven't heard before!
I'm surprised this thread 'died' as it doesn't seem like the answer was ever found..
I've just posted here:
http://forum.slowtwitch.com/...psed;page=last;#last and mentioned a little about the risks of inadequate nutrition. The reason I post this is that one poster mentioned 'eating for the weight you want to be'. This can lead to problems if you want to be significantly lighter than you are, therefore leading to far to great an energy deficit.
If you (one) are (is) able to eat to a specific kcal number it does sound like you are being quite specific with your nutrition. In this case if you are slightly out it does not matter. It is far to hard to give an accurate figure for energy expenditure for running and swimming due to the differences in efficiency between individuals... however, those lucky enough to have a powertap on their bike can get much more accurate readings due to relatively small differences in cycling economy.
Excellent and telling advice given here:

To the OP, it's critical to log your workouts in order to figure out how much you should eat. It's amazing that after a 2-3 hour HARD ride and brick run how much food you actually need to eat just to maintain your weight. Opposed to rest or off days, when that number is drastically reduced. I find that if left to just eat naturally I eat too little on big hard workout days (and suffer the next day with lethargy/weakness) and eat too much on off/rest days.
This is something I see all the time. Overeating on rest days and under eating on and prior to training. When really it should be the exact opposite!
All interesting stuff! :-)
