I think that advice to avoid carbohydrate is, with respect, bad advice. The thing is to avoid processed food high in sugar (and fat). Starchy carbs are very good because they are satisfying. The less processed the better. All you need to do is exercise portion control. Pasta and bread in moderation are brilliant, as are spuds and rice. Also, most of the fibre we need is intimately bound to starchy carbohydrate. I lost three stones in nine months and I did not even think of giving up bread, spuds and pasta. So I think it's outrageous to say that you can't eat carbs and lose weight. That is the route to ill-health.
