The problem w/ the mags is that they don't really seem to give "real world" info. Maybe some of the articles are good, but stuff like "Monica Brandt's Olympic Prep Diet" or somethign like that don't often include the reality details, like the diuretics or other controlled substances that this person might be using., So the info is just skewed and sort of misleadign or useless. Or the photos & body stats are at competition time and not "regular life" so it sets expectations in a misleading way to the people reading.
Again, just my opinion because "fitness" is still a media industry and as such is going to suffer from the usual BS factor. I prefer to get real info and the web is usually the best for that because nutrition and fitness are such "inexact" (or perhaps better, not appropriately quantified) sciences. Too many factors to say "Buy X Diet - you will lose 20 lb of fat in 10 days". Better to really build an awareness and start to understand your own body and what it can do / how it reacts, etc.
