I am not sure why you cant just calorie count or some other diet/exercise.
CD is not the only diet that works.
I would be very worried that you feel you have to wait a whole year before you tackle your weight.
Walking and healthier eating are free, think about the food you do eat (maybe write a food diary) and how much exercise you do. Then decide how you can make small changes and in a years time you may be at target (and it also be a healthier and cheaper more sustainable method).
Having spoken to my CDC about how many people drop out after 2 weeks of CD, the number is very high (and I have a great CDC) and I would hate for you to wait a year and then find the diet isnt for you.
It is a very hard diet to stick to, I live with my BF, but have no children and I feel so selfish doing this diet as I have to turn down so many social/family occasions, or if I do go I feel like I am not part of the group as I am not eating or drinking, and this isnt me just being silly, the diet makes other people very uncomfortable.
I also think it is un-healthy to do this diet in front of children, I understand that for most people it really is a last resort (me too after suffering from eating disorders for the last 10yrs). But if you can find another approach to losing weight, Please DO IT!
