Just a quick update for those who are interested. I'm about 3/4 of the way through Phase One. I'm now at 127.5kg, down 2.5kg from when I started. A little slower than I would have liked but at least it's progress. I've been increasing the intensity of my exercise as well, now doing a 23 minute interval session on the bike, 20 minute intervals on the treadmill, 1km swim, plus weights, three times a week. I'm following the Couch to 5K intervals program for the running portion. I've stopped being hungry all the time as I was in the first week, and no longer craving the footlong subs, curry and pasta that I was in the beginning.
