Metabolic Rate: The initial part of speedy weight loss often comes with an increased metabolic rate as a result of energy required to process food. However, as weight loss continues, the body may lower its metabolic rate in response to reduced caloric intake. This is a survival mechanism that helps the body preserve energy balance during times of perceived starvation.
