Why is it that ladies always make excuses for being fat?

if you notice in the USA most ladies are fat and it is all their fault, they eat all kinds of fatty foods, and most of them stay home and do not go to work, some ladies say that they dont have metabolism or they just say that cant loose weight, I mean ladies have very easy lives why do they make these excuses?? All ladies should be skinny so the man can carry them over the threshold, it is a shame when a lady is so big a man cant pick her up.
