Because paraffin wax is relatively rare as a diver's meal?
Carbohydrate has a respiratory quotient of 1 and fat of 0.7. Perhaps the typical diver's meal averages out at 0.9? Taking into consideration the methane...
I would suspect it also has something to do with the body getting its energy from aerobic or anaerobic activity. I suspect its very difficult for a diver to be at a high enough level of activity for a long enough time to switch over from burning carbohydrates for energy to burning fats. As a general rule in long distance running it takes roughly 30 minutes of fairly high intensity running for the body to make the switch. I am not an expert on this subject just my guess.
