The diet does not bring the desired result, if it is based on a sharp reduction in calorie intake. While some, it appears that it is fasting guarantees the best results. But suddenly canceled pounds - a huge stress to the body! In addition, the body is "grief" begins to put out the water, leaving the fat "in reserve".
