What does eating clean mean? I see that phrase thrown around quite a bit, but I do not believe it is anything more than a cultural meme the diet/exercise/industrial complex came up with to scare us into futility. If one "eats clean" then that same person can "eat dirty"? The Twinkie Diet was nothing more than one researcher's attempt to see if people could lose weight on an "anti" low carb diet. And he did. The media got a hold of his study and ran with it. I do not think he promotes it as a life style change. He did not just eat Twinkies either...his diet "evolved" into 1200 calories of junk food a day. Tom Naughton was one of the gentlemen who watched Super Size Me and cried "bologna"! (Literally) His term. He made a responding documentary called Fathead. Interesting stuff, and he did eat fast food for a month and lost weight. Roy Walford wrote Beyond the 120 Year Diet. His research showed, in "lower life forms", life could be extended through calorie restriction. It is presumed that such practice could extend human life significantly as well. Aubrey de Grey, at Oxford (Cambridge?), believes he is on track to extend human life expectancy indefinitely. Hugh Nibley presented an interesting essay/talk on "the boredom" of endless life titled "But What Kind of Work?" it can be read in Approaching Zion. It certainly would be a challenge, but according to Mormondom's gadfly, worth it.
