If you've watched any of those survival shows on the Discovery channel then you have heard them talk about starvation. I watched one where they said that it takes 30 days for a man to starve to death and a bit longer for a fat man. So I've also had conversations about Methheads where people talked about them losing their teeth. I asked why they lose their teeth and I've been told that they stopped eating. Did they really lose them for some other reason? If you were starving to death, how long would it take for you to lose your teeth and have other permanent type damage? What about things like a potassium deficiency damaging your heart?
