Yes, it seems to have good bits of info. You can find it at Borders or other book stores. It only comes out 4x a year?? I can't remember. May be why you can't find it. You can look on their web:
I do have one small issue though. It seems there is usually conflicting info. For example, they may have an article bashing certain diet pills and on the next page you see a big advertisement for it!
Good quick reading on the treadmill though. Just my .02
