How much are you training?
IF is primarily used by athletes for losing weight while preserving as much muscle as possible. They eat in a 3-6 hour window after an intense workout typically consisting of an hour of weight lifting, and then 2+ hours of sparring and grappling.
The whole point is to get to eat as much as you can to give your muscles adequet nutrition after ripping them up, then not eating the rest of the time to get your body to use itself for energy. Gotta be fairly high protein, and combined with serious training.
I'm 5'8" stinks being shorter
Summer 2011- 215 lbs. Peak weight

September 2012- Made my goal of competing at feather weight for Bjj (under 149 with a little water cut)
Now I'm just trying to maintain around 152ish to leave me in easy cutting range. Also trying to relax and eat more like a normal person now, balancing enjoying life and staying healthy.
