Increasing my weekly yardage seems to have increased my hunger. How can I determine the calories really expended during swims of various lengths or intensities?
And when the office hits the all-you-can-eat lunch buffet, how many laps equate to that second or third serving? (Not giving up the food can justify extra time in the pool!)

Emmett says the really poor swimmer can burn fully as much
energy as the really good swimmer over the course of an hour.
This gets back to the original question...
I saw a formula once that basically said:
calories burned=weight of swimmer x factor for speed x minutes
This book had the only realistic rate of speed factored into
the equation that I have seen--in this case it was 500 yards
in 6 minutes 40 sec = .097.
So, according to this source, someone weighing 210 lbs x .097=
~20 calories/minute when swimming 100 yds in 1min 20 sec.
So if you could maintain this rate of speed over an hour,
you'd burn ~1200 calories per hour. Someone weighing 105 lbs
would burn 600 if swimming at the same rate of speed.
Various other levels of effort were roughly proportional.
Unfortunately, I can't remember that title or author of the book,
but it had similar factors that could be used for running, walking,
biking, etc.
