Walford's the researcher who discovered that mice live longer on a low-calorie diet
His fellow Biosphere 2 scientists had to restrict their rations for several months and the initial (physiological) results were encouraging. A few years later he had lunch with Alan Alda on Scientific American Frontiers and demonstrated his nutritional software. I remember Alda asking Walford if calorie restriction was working and Walford said "I think so but I can't claim success, I've only been on it for 10 years..."
Walford died of ALS complications last year. Unfortunately he claimed that the syndrome was brought on by Biosphere's atmosphere contaminants and it's a little difficult to believe that his calorie-restriction lifestyle was not an issue. I don't know enough about the issue to make a decision either way but I'm cautiously paranoid.
The guy lived a pretty amazing life and I think his research is compelling. I carried around 20-30 extra pounds for nearly two decades and I'm surprised how much my health has improved since losing them. Activities that I used to pass up (running) are actually enjoyable now and I've had no joint pains. I suspect the vast majority of Americans have health complications (BP, cholesterol, joint pain, insulin levels, hypo/hyperglycemic, risk factors) that would largely disappear if we'd lose 15-25 pounds.
Optimizing my nutrition and reducing my health risks appeals to my inner analytical engineer, too, but I doubt that'll make me give up ice cream or beer. Walford probably found a tiny grain of truth that's subsequently been surrounded by a feeding frenzy (so to speak) of nuts & zealots. However the first few steps down that path has taught me a lot about diet & balance that seems worthy of further exploration. Just as soon as I finish my second breakfast...
