Quizplus · Accepted Answer

When the body receives fewer calories, the body's response is to reduce the basal metabolic rate (BMR). This means that the body is burning fewer calories at rest, making it easier for someone to lose weight simply by eating fewer calories. However, it is important to note that reducing calories too drastically can also lead to negative side effects such as slowed metabolism and loss of muscle mass.
