The food we eat today, high in sugar and easily digestible carbohydrates, is not only making us fat, but is putting us at risk of type 2 diabetes, strokes, dementia, cancer and a lifetime on medication. More than a third of adults in the UK now have raised blood sugar levels and most don't know it. In this timely book, Dr Mosley explains why we pile on dangerous abdominal fat and shows us how to shed it, fast. He demolishes common myths, such as the claim that steady weight loss is always better than rapid weight loss and that those who lose weight rapidly will inevitably put it back on.
