Plenty of Sleep
Dr. Darden also discovered that plenty of sleep was essential to fat loss. In his research he noted that subjects who were sleep deprived did not lose fat as easily as those who were well rested. It seems that calorie restriction is fairly stressful to the body and any further stressors can result in a protective slowing of the metabolism. My own theory is that a calorie restriction sends a biological signal of starvation and decreased sleep sends a signal that the organism is having to stay up to search for food, or it has to be vigilant because its environment is unsafe. These are probably powerful biological signals that cause a protective slowing of the metabolism.
