Point, I suppose. I guess I should have said, "Stop consuming the Calcium your body needs to manufacture the imbalancing chemicals that cause you to go crazy." It's a better analogy, since my point is that it's entirely possible (as a for instance) that her body devotes a certain percentage of all the calories she consumes to fat building, so eating less would decrease fat, but also leave her without the energy to survive. The point is that, if you don't know the actual particulars of the disease, don't go around calling the victims "LAZY FUCKING PIGS".
It didn't have to happen overnight. I would submit that it probably happened over a long period of time, in fact. What's your point, though?
If someone said, "I have cancer," would you tell them, "You should've stayed out of the Sun, asshole."?
