Miss r and others do have a point. I know a couple of CDCs who have, themselves, regained all their weight plus plenty more. This is by no means unusual. The problem is not the diet. It is, I honestly believe, the too-rapid reintroduction of carbohydrate foods.
Even following the steps to maintenance and beyond does not guarantee that the old cravings won't strike again, with terrible force. I speak from personal experience, here. When they do strike they can be devastating. Maintenance is a long, slow journey and has to be approached with great care.
For the carb-sensitive I think this is doubly true. Extra carbs can often mean the return of hunger, cravings, and the tendency to nibble we were able to avoid on a TFR diet. It's no coincidence that many just love to have food 'taken out of the equation'. It is when the food is reintroduced that the problems so often start.
Don't be too hard on people like Miss r whose own personal experience of a VLCD was not encouraging. Opinion is sharply divided on the value of TFRs over the longer term and statistics show that most dieters, on any diet, regain the weight. Usually quickly.
I think if people low carb after a VLCD, or at least go low GI, they have a far better chance of success. For myself the answer proved to be vegetarian Atkins. I can never overdo carbs without serious consequences! I lost ten stones and over 13 years only regained two after the death of my father and uni Final exams. I have now lost a stone of that regain.
Miss r was most polite and not at all nasty or accusative. I agree that this is a support forum but surely a polite and reasoned comment is not off-limits? Others are free to disagree, after all.
.....BUT I never will say cambridge is unhealthy or dangerous, i think it's a fab diet if you're in the right mindset
