I have been following the Zone Diet for the past year with great results. I am intrigued by the IF concept, but wonder about the implementation for those of us who typically workout in the early evening. Most of the folks that I know who are experimenting with IF typically workout first thing in the morning, eat the day's worth of food over the next 4-6 hours, and then fast until the next day. I worry about working out until 7-8 pm and then trying to cram 4000 calories into my system over the next 2 hours prior to going to bed. Any advice or thoughts on potential implementation you could offer would be helpful.
