Drawing from the latest sleep and nutrition research, Dr Harrington reveals the science behind what happens to our bodies when we don't sleep, and how this critically affects our appetite-controlling hormones, our metabolism and how we think and feel. She explains why proper sleep is the missing link in the on-going and often agonising attempts to lose weight. This books shows how to develop habits that deliver high-quality, restorative sleep. She provides a plan for healthy eating and a guide to making sure our improved eating and sleeping habits lead to lasting weight loss. The Sleep Diet is both a scientifically proven approach and a practical guide to losing weight and improving overall health and wellbeing.
