A. A dieting plan I could stick to consistently. Because I was only eating during a small window of the day, satiety wasn't a concern. I found myself eating "unclean" foods for at least some part of my meal each night, which basically nullified any cravings on a nightly basis.
B. A solid training program (similar to PHAT except 4 days/week, upper/lower) + HIIT
C. Unprogrammed rest days (these were key! Basically means that I took the day off whenever I started feeling run-down)
D. Proper sleep
The crucial supps were the stims: and ECA. Why? Typically when I get into single digit BF%, my energy levels drop, regardless of how wholesome my diet is. It gets tough to go and do an training session and finish it off with HIIT on a near daily basis. Without some potent "extra help" in the stimulation department, I don't think I would have sustained the drive to complete the cut.
