Muscles vs Fat
I don't know if this has been discussed before - but i guess we can all agree that fat is a good insulator and increases the amount of time people can spend in cold water.
Say IF you would retain your body fat percentage but instead build muscle - would it keep you warmer longer?
(As per the old a larger person has a lower surface area to volume ratio)
But i take it 5kg muscle gain would help less compared to 5kg fat gain as muscle is more dense?
(the reason for this thread is that i have lost 4kg fat!)
