Our body&#x27;s software is so hopelessly out of date.  It&#x27;s programmed to preserve fat at all cost: something quite useful, say 2 million years ago when famines were happening almost every day.<p>Medical and nutritional science needs to advance more quickly in this regard.  Currently, it&#x27;s going at a snail&#x27;s pace.  I mean, we understand the entire creation of the universe, but the most advanced nutritionists in the world are barely aware of the basic mechanisms which govern our fat production, not even understanding how it works.  So far, all we have is theories, hypothesis, correlations and some compelling experimentations.<p>Personally, I&#x27;m waiting for the iBody app to come out.  iBody, will allow us to control our metabolism at a cellular level, dialing it up or down at will.  We&#x27;ll be able to control our appetites and hungers at the push of a button too.  But, at this rate, who knows how long it will take to get this off the ground: 100s of years, thousands?  Come on investors, this is a multi-trillion dollar market.
