Actually, this just shows swimming isn't as effective as land based exercises
for weight control.

>From the article:

   "Presumably," speculates Professor Gwinup, "swimming in cold water
   stimulates the appetite to increase caloric consumption."

 Indeed, there are suggestions that swimming doesn't cause the same drop
 in appetite that accompanies heavy running and cycling training. Many
 people feel extremely hungry after training in the pool, and may simply
 replace all the calories they've burned with a large post-exercise meal.

Note the mention of cold water. If the water were warm, as our hominid
ancestors would have had in their environment (being situated in the
tropics or nearby) would there be any or as much fat?
