Overweight 'should be protected'

smashing up your brain (or doing anything to your brain chemistry, such as chemotherapy, for that matter) can do all sorts to you, such as increased weight gain (which in turn can be due things as varied as altered metabolism or altered impulse control) to apparently inducing paedophillia!
Your body is governed by a balance of chemical cascades alter that balance and their maybe a physical result such as increased fat deposition. But now we are wandering into the hazy world of free will and conciousness (which is a potentially useless by product) and things might get outta hand.

So it's only a matter of time before paedophiles can now just put it down to a chemical imbalance and get away with it?

How long is it gonna be before we're not allowed to call them paedophiles because we might hurt their feelings?
