For years we've been told that a low-fat, high-carbohydrate diet is the way to lose weight. But anyone who has followed the regime knows it isn't - Rick Gallop found that out the hard way.
Frustrated, he set out to discover a diet that was genuinely healthy, that wouldn't leave him starving and that would actually work. When he came across the Glycemic Index - or G.I. - he knew he'd found what he was looking for.
To lose weight it's critical to avoid foods that have a high G.I., such as cornflakes and watermelon, because they are digested too quickly. Rick Gallop has created the easiest, most satisfying eating plan possible in The G.I. Diet by listing foods in one of three colour-coded categories based on their G.I. ratings.
