i4u writes "Rumors about Steve Jobs' health have been flying high again after Apple announced that he will not be holding the keynote at the Macworld 2009. Today Steve Jobs issued a letter with a rather personal update on why he was losing weight in 2008. The reason for losing weight in 2008 is a hormone imbalance that has been reducing proteins. The remedy for this nutritional problem is relatively simple and straightforward according to Jobs. Steve and his doctors predict that he will have normal weight again by Spring. So stop the rumors and enjoy Macworld 2009."
