When we feel happy we smile or laugh. When we feel sad we cry. These are physiological responses to our environment, and everybody has them. They are written into our genes. When we lose weight we evoke a starvation response, which means the body reacts in a very specific way. One of the body's responses to starvation – or dieting – is the returning of the weight - fat - that has been lost. The Body Controlled Diet not only explains the starvation response, it also offers the dieter the only known biological way to avoid it. In plain English, The Body Controlled Diet – for most people – is the only way to lose weight and stay slim.
