IIRC the Warrior Diet is a sort of IF, so yes, there are a number studies that have shown an intermittent fasting pattern can have a number of benefits for improving body composition and possibly health.
There are several variation to the basic idea, e.g. 1 day eat 1 day fast, what I do is something that's modeled after the LeanGains version and has elements from other authors (e.g. Lyle McDonald, Mark Sisson) plugged in. I think the LG site (www.leangains.com
) has some information and comparisons among the different types of IF programs, it may be worth some searching.
The pattern I'm following is roughtly 16 hours fasting, 8 hours feeding window, that typically start from 8 pm. Sometimes I fast for more, sometimes less. I don't eat a lot of carbohydrates hence I derive most of my energy from fat and proteins, but I do eat vegetables and supplement with a light multi-vitamin product and omega 3.
Only thing that annoys me a little about LeanGains is the author is prepping a book on it and some of the key basic elements haven't been clearly documented as he's basically keeping them to himself for the book. E.g. I know the full program relies on calorie counting but I never found any details about how this should be handled. And while I hate calorie counting I would still be interested to see what I might be missing...
