Explain the reason for rapid weight loss in LCHP dieting.

The reason for rapid weight loss in LCHP dieting is that a low carbohydrate intake forces the liver to produce glucose. The source for most of this glucose is body proteins  your lean body mass, including muscle. When the body uses protein instead of a combination of fats and carbohydrates as a source of energy, weight is lost as much as 10 times faster. This is because a gram of protein produces half the amount of energy that fat does. In the case of muscle protein, one-fifth of protein is mixed with four-fifths water. Therefore, each pound of muscle yields only one-tenth the amount of energy of a pound of fat. As a result, most of the weight lost is in the form of water, which on the scale, of course, looks good.
