I'm fairly new to this type of diet, but have been on the Zone Diet for several weeks with excellent results in terms of weight loss and energy level. I noticed a post (sorry I have deleted it so cannot quote it) mentioning that Barry Sears' original book "The Zone" is now out of date in some respects. I am sure that must be true, given that the book was published in 1995. I'm curious though to know in what respects the information in it has become outdated. Can anyone offer information about this?
