As part of my research into this diet, I’ve been looking at success stories, failure stories, bad press from people who have never tried it, and any medical research good or bad that I can get my hands on.
The main conclusion that I have come to is that those people who knock the Cambridge diet just aren’t understanding the whole package of it. It is more than just a starvation plan. Looking at the success stories (and by success I mean those people who have lost the weight, gone through the maintenance program and kept the weight off even after the maintenance program have finished I can see plenty of things to learn from.
As far as I can see these are the main objections to the Cambridge diet that are voiced on the internet, plus my own response to them:
1: It tastes disgusting. Well I’m not exactly expecting gourmet food, and I don’t expect its going to taste as good as the sweet sickly gunk that I’m eating at the moment, but it’s only for a short time & I know I can do it. Besides which, I quite like powdered milkshake, mousse, cup a soup, pot noodles and all kinds of chocolate covered candy bars, so I’m sure I can survive on this.
2: As soon as you finish you’ll just pile the weight back on because it hasn’t taught you a new way of eating. This one is all about mental attitude. If you do it for a few weeks than go back to eating exactly what you did before then you will regain the weight, and possibly more as your metabolism will have slowed down a bit. The whole idea of this diet is that you use the time off food to wean yourself off some of your previous vices, and when you do introcduce food again (in a slow and controlled manner) you start to relearn good habits and portion control.
I really think I need to break certain snacking habits - on previous diets I’ve allowed myself to have lots of little treats and counted them in, until eventually they just took over and I was back to square 1. This time I won’t have to negotiate with myself for treats - there will be none. If I was trying to give up smoking, I wouldn’t try to find a smaller cigarette or a different flavoured one - I would want to go away from the places I used to smoke and learn different ways to behave.
3: 400 calories is a ridiculous amount and not enough to live on. Reasonable point. So I’ve decided not to do the lowest level of the diet - after all I’m not chronically obese. So I’m going to start on the 700 calorie programme. Even that seems very low compared to other programmes I’ve been on & this has put me off in the past. I was sure that it had to be harmful to the body going into starvation like this
This is where the internet has been great - I’ve seen lots of stories of people who have done it successfully and suffered no ill effects. Most have experienced vast improvements in their health - blood pressure, cholesterol etc. When I tried to look for people who have ruined their health by doing it all the stories I found were from the 80s, when it was only 300 calories and less well researched than it is now. Now the medical consensus seems to be that 400 calories is the minimum for health and I am going to have nearly twice that.
For the most part people who are on the net saying that it doesn’t work either haven’t tried it, or have tried and failed to complete it. Anything works if you do it properly and I believe that Cambridge does have a good and proper way to reintroduce proper eating - you just have to follow it.
4: Its going to wreck my metabolism. This criticism comes mainly from me - from previous studies I have done in the area of health and fitness - including my personal trainer training. I realise that my metabolism will go down slightly and that when I have finished the diet I will have to eat less food than before if I keep my fitness at my current level. But I see Cambridge as the first step on my health and fitness programme. When I am on the 790 calories part of the diet I will not be able to exercise as regularly as I would like to nor at the intensity that I normally would. But as I start to increase the calories on the maintenance stages, there is nothing to stop me slow ly but surely ramping up the exercise. Once I am back to normal levels of eating, I can start a self-designed exercise programme to boost my metabolism back - I am a fitness professional after all. With the advantage that I will be starting to exercise without the 3 stone of surplus flab round my waist, which should allow me to do a bit more.
5: I’m going to feel hungry, grumpy and tired. Hell I already do feel hungry, grumpy and tired most of the time anyway. It’ll be worth it to just feel them a bit more acutely for a few weeks - then once I get properly into ketosis and the weight starts to come off I look forward to having more energy and feeling fabulous.
I’ll probably think of more stuff as I carry on preparing, and who knows what ugly thoughts will come into my head once I’m on the diet. But at least no-one can say that I went into this with my eyes closed.
