I am very over-weight and I saw details of the diet in a magazine in February - I started in March. DH and I had a long discussion about it, and with our DC, and we decided, if it enabled me to live for a few years longer, it was worth spending our savings. So I have been doing it for three months and have already lost three stone. I visit the clinic every week for treatment and to pick up the food sachets which I then make into meals. I am absolutely slap bang in the middle of the estimate of the time it would take to lose the weight I wanted - 22 - 28 weeks (should be 25 for me).
I am very, very focused and have kept very rigidly to the diet (I am also very well aware of how much money it is costing, so why would I not stick to it?). If you know that by having a sweet or biscuit, it will take you three days to get back on track and you will have wasted over £200 it concentrates your mind wonderfully.
My problem with ordinary diets is that I am happy to do them for a few months, I lose 1 - 2 stone, then I get fed up and revert back to how I was eating before and the weight always goes back on. The particular clinic I go to helps with maintenance, etc., which is very important to me. I have deliberately not mentioned the diet before as I knew it would be contentious - however, it is working for me and the difference to my health is staggering. My health is being monitored by a GP and, for me, giving up 28 weeks of my life to be fit and healthy again was worth that (as is the money, to be honest).
Anyway, back to nails - I have no idea whether or not the QH are helping, just saying that my nails are definitely better now.
