I don't think its cheating either. I live in fear at the moment that I won't manage it, will have wasted my money and let myself and everyone rooting for me down!
Its a very difficult diet I think, but the results are the quickest available, which gives us additional motivation, which then overcomes how hard it is, does that make sense? Its a good lesson in how having the correct motivation for anything in life can help us to then do seemingly difficult things.
I have a vague and distant memory when I was made to climb Ben Nevis as part of a team building thing when I was 18. We wandered along getting ourselves up the mountain, to be honest none of us wanted to do it, we were all grumbly. Then when we were half way up, our clever instructor played a wee mind trick on us. She said.... I can see some of you are struggling, so anyone who wants to can stay here, at the half way point, and the rest of us will go to the top, and collect you guys on the way back down.
Well, something interesting happened in my head, and it wasn't just me. We were all kind of 'oh my God.... you've dragged us half way up and NOW you don't mind if we stop? and then we go home and say we went 'half way up a mountain' no bloody way, you've dragged us this far you can bloody well drag us up the rest of it!!!!'
So.... after that I will never forget how the journey changed. It was SO much easier, of course it was still difficult, but not like it seemed before. The difference I guess is that we had switched from doing something we didn't want, into having made a choice, and with that choice, the motivation then arrived and got us to the top! I may have forgotten bits of that journey, but never the lesson. It was 18 yrs ago, so half my lifetime.
I see this diet as the same. We have all tried every other thing going I assume, and most of the time we don't want to be there. The journey just seems too long and too hard. However at this point I'm guessing most of us are desperate to be here, desperate for the answer to our weight issues, and cambridge is a much shorter, faster route. Because we can see results the motivation (hopefully) remains good, but its still the same mountain we are climbing!
Other diets allow all sorts of 'treats' to keep the slimmer interested, all we can hope for is a chewy bar! there are huge sacrifices we all make every day, this is NOT easy! Our 'treat' is seeing the difference it makes.
