I will try to summarise the main points but it is a reasonably long book that you can get on Kindle for £1.99 and it is pretty good.
Rule 1 is to have the right attitude, essentially feel positive about it rather than deprived.
The first suggestion is to make a list of those times when you snack on sugar as a habit and work out what you are going to do instead.
He suggests cold turkey but says that gradual cutting down can work as long as you keep a sugar diary and are really strict about it.
Essentially the rule is no frutose except that found in vegetables and two pieces of fresh fruit per day.
Look at labels - dairy products should have 4.7% sugar as that is the lactose which is ok, bread should have as little sugar as you can find - I have gone for hovis wholemeal granary at 2.4%. Avoid anything labelled as low fat as it is likely to have added sugar.
He suggests snacking on nuts (which I am doing whilst being nervous about the calorie content) - He does say that as the sugar addiction disappears the snacking will naturally reduce anyway.
He gives a bit of a mixed message about the occasional bit of sugar - first of all comparing everyone to alcoholics and saying even a little will set us off but also saying that party food is for parties and having a dessert someone has cooked at a dinner party once in a while is not the end of the world.
Drink only water and milk - low sugar alcohol allowed in moderation
withdrawal is worse for women and can last a good few weeks but hopefully with only be up to two weeks and will feel like a nagging hunger and head aches. After that there should be a moment of revelation when you realise that you no longer crave sweet food.
sweetners are fine in relation to sugar addiction but who knows if they are fine in the long term for health. Use them for a bit if you need to but you will find you don't need them forever.
Once withdrawal is over you can use glucose for baking cakes etc. - My thoughts on this is that the calorie content will be the same so I am not planning to do it all that much. The theory is that glucose will fill you up properly so you wouldn't over indulge this way but will maybe have less supper later on for example.
Anyway a bit of a long answer to your question and to be honest your plan sounds good to me and a lot simpler! What is the Whole30?
