Can anyone please advise me on the following?

I am not used to measuring in cups. I prefer to weigh items. Is there a book in the UK that will tell me just how many carbs there are in items [such as the basic items to be used in the first 2 weeks] per ounce or gram.

Many thanks.

ps. This site is a God send to me. I have tried the plan before and failed but I know that with all the ideas that are on this site [such as where to buy food etc.] I will not fail to loose the weight.
