Biggest Loser comparison pics

When I look at the comparison photos from the Biggest Loser the upper bodies look amazing , but why is there such little change in the legs? Especially their calves.

because even fat people can have good calves.

I've noticed that with myself...my calves don't change much my thighs do however and upper body. So must be something in the way muscle is designed. Of course may be because that seems to be one place where fat doesn't build up as much!
