Poisoned Waffles
The evidence is clear that obese employees require more medical care and sick days than non-obese.
What about the hot employees hooking up more frequently and getting STDs and calling in sick with hangovers?
I think there are too many variables at play to simplify it down to "fat costs X more than thin".
In any case, so what? Even if the fat do cost more, should that affect how they are treated? It's (much more easily demonstrated) fact that employees with children cost a company more than employees without children, but nobody (I hope) is suggesting anything be done with that knowledge.
