Recent research has shown that a diet that is very low in carbs and high in good fats is effective for weight loss, can counteract many diseases and also help athletic performance and endurance. The drawback is that it is difficult to stick to - because most people love carbs. But, as The Hybrid Diet demonstrates, we don't need to choose. The human body has been designed through millions of years of evolution to burn two different sources of fuel - glucose (which comes from the carbohydrates in fruit and vegetables) and ketones (which are made in the body from fat) - and to switch between them when food is scarce. The point of The Hybrid Diet is to show you how to make the best use of both options when you need them, and how best to switch between them. In their quest to discover the perfect diet, leading health journalist Jerome Burne and nutrition expert Patrick Holford have examined the latest cutting-edge science and have put together a plan that is sound, simple and delicious - one that is based on how your body works best.
