in addition to that, you should tell your friend that he can measure his bodyfat 304223425 times a day, but that number isnt going to fucking matter as long as hes still got the tits. what difference does it make?
he wants to realize just how fat he is? couldnt he just look at his tits and figure that out? tell that guy to take himself and his tits to a gym and start working, eat sensibly, and worry about his bodyfat after he no longer has tits.
