There is a whole diet plan behind the warrior that I don't subscribe too, but on some days I only eat once (the warrior) and on others I eat twice. It's hard to get enough protein though in one sitting so I eat twice in the evening more of the time. The fast five eating plan an IF plan with a smaller window of course. You can find that at fastfive.org. Martin Berkan leangains is also someone that knows his stuff about IFing.
Regardless of the eating window size, I think that any IF plan that you can stick to will make fat loss easier.
