I have now lost about 16 pounds. Not a huge amount but dropped a good dress size and look and feel a million times better.
At first I dropped steadily at about 1lb a week then about 1/2lb a week. But now I find that the pattern is to stick around a plateau going up and down by a pound or two (I now weigh every day) for about 4-6 weeks then drop about 3 lbs. It has happened 3 times now. Each time I think I have stuck but keep doing the same thing, and eventually it drops again. I have heard other people saying something similar and since I have been doing this for so long I wanted to add my experience.
I just want to encourage everyone to stick with it. If this is to be a way of life, and not a fad where you pile the weight back on, you need to find a way to sustain this. So, I have never gone to 4:3, I have rarely missed a week (although occasionally could only do 6:1 due to social commitments). I have just plodded on, fasting on Mondays and Thursdays and eating 'normally' the rest of the time (not calorie counting). I exercise twice a week but did that before starting this.
Sometimes when my weight has stuck I feel a bit slimmer but think I must be imagining it as I have not lost weight. Often this is just before the scales drop again. Strange.
