I've been doing this for over a week now. I have lost 13lbs and I seem to have got over the hunger pangs - though it really was touch and go on days 4 and 7, and I felt miserable and hungry for 3-4 hours on each of those days. Our local pharmacy sell the female shakes to men and they just tell us to have 4 a day instead of 2 large ones. Apparently it works out just the same. I'm in a better pattern of drinking the shakes now. I didn't eat breakfast when I was eating (I'm never hungry in the morning) so now I have my first one at lunchtime, one after work, one about 8 and one before bed - it works well for me, tonight I didn't really feel like having my fourth one as I felt pretty full up, but I had it anyway to prevent hunger from keeping me awake. I haven't felt hungry at all today, so hopefully I'm past the worst. I was seriously thinking of jacking it in last night, but I hung on because I'm tired of looking all 'jowly' and getting middle aged spread. It looks bad on blokes, Clarkson on Top Gear last night had a sizeable belly on him and it just makes him look awful. Well, that and his 'haircut'. I'll keep going until I feel I can't do this any longer or until I get to my goal of 14 stone. I'm 16'5 at the moment, started at 17'4, so I reckon there's about 6 weeks more to do. It may take longer than that but if I take up running again that might help to accelerate the weight loss. It gets easier, they say, and that is certainly what I'm finding. The hard times seem to come just before it gets easier; a lot easier.
