Answering questions such as what a calorie is, how many we need, how much we should weigh for our height, what our metobolic rate is, and how it affects weight loss, this is a guide to keeping track of your calorie consumption and managing your weight. It classifies foods by type, so that, in a supermarket, readers can compare the different types of, for instance, cheese, fish or bread, and can easily calculate the calorific value of, say, each individual biscuit or each slice of bacon. Low-calorie recipes are included, with a view to demonstrating that food which is low in calories does not have to be equally low in taste.
