Well done SV, you have done really well, and I know 448 seems like a long time, but it isn't really.
Compared to you I sometimes feel a cheat because I only joined the ff thread in Feb (I think). But did lose 2 stone doing pmk on my own the year before last, unfortunately due to circumstances beyond my control I gained weight again last year.
This time I am doubly motivated, as in serious need of getting rid of boobs because they are knackering my back, and am too chicken to have them operated on.
setting time targets brings out the diet mentalist in me, which has never ever worked for me, so I love the chilled approach of pmk, your body loses at its speed which has to be more healthy
