Yes, Rachel Zoe, you can be too thin

Yes, yes, we know how the old Duchess Wallis Simpson saying goes: "You can never be too rich or too thin."

Wallis was a very fashionable lady with some very nice jewelry. But while the jury is still out on whether one can be too rich, we hate to break it to you that sadly she was very, very wrong on the "too thin" part.

Now, we're not talking about the unfair genetically-blessed thinness that many young Hollywoood starlets possess. Just you wait, come 30 their metabolisms will change and years of eating whatever they want whenever they want, keeping late hours and eschewing exercise will catch up with them.
