Getting energy

About this book

"Every part of your body needs energy to keep it working. Your muscles need energy to keep you moving and your brain cells need energy to pwer your thoughts. The energy your body uses comes from the food you eat and the oxygen you breathe. Getting Energy describes how your body generates energy. It shows how you digest food and turn it into usable energy. It explains what makes us feel hungry and why it is important to eat enough, but not too much, food. And it outlines what can happen if any part of your body's complex food-processing system doesn't work properly."--Back cover.
