I've been trying to do the IF approach for a while now. My work/kid schedule sometimes gets in the way but most of the time I can just get up in the morning and not worry about breakfast or lunch and then come home a lift and really really plow some food away in my 6 or 7 hour window. I've actually gotten use to working out in a fasted state and enjoy it now (cuz I know there is gonna be a 6 egg omelet on the other side)
you guys follow http://www.leangains.com/ at all? I'm considering becoming one of his clients to help me lay out the IF program a little better. 2 words - protein fluff!
