supplement to calories burned during swimming

I have read shomewhere along the way that swimming in COLD water may produce a thermal-type response from the body and cause it to develop a layer of fat to accomodate and survive. Or only people with protective fat will try to swim in cold water because their bodies are suited to the activity. Just like a guy who is 5"5 won't generally go for basketball. Probably a combination of both genetics, adoption and nutrition. I remember seeing a report a couple of years ago on "60 Minutes" about long distance cold water swimmer Lynne Cox ("Swimming to Antarctica"). It showed her swimming near Antarctica. The reporter commented (correctly) that she had a large amount of body fat because that is the demand of her sport and does not in anyway mean that she is not a great athlete. I couldn't help thinking (and I don't mean this as an insult) that she reminded me of a seal. She was completely suited to the demands of her chosen sport.
