The latest article over at SAGE Crossroads talks about calorie restriction (or "CR") at some length. As usual, they err far to the side of caution and central regulation. As someone who practices CR, I can say that it's neither hard nor torturous, as the article would have you believe. The article includes interesting mention of current medical research into drugs that would mimic the beneficial effects of CR. Quoteable quote: "studying CR -- and determining how it works -- is important because this intervention provides the most promising avenue of research on forestalling aging."
