Question

Quizplus · Accepted Answer

The concept of a weight set point suggests that the body has a built-in mechanism that maintains body weight around a physiologically programmed level. The evidence from prisoners who, despite being fed large amounts of food, gained less weight than expected and returned to their original weights upon resuming a normal diet, supports this theory. It indicates the body's ability to regulate and maintain a stable weight over time, even when significant dietary changes occur.
