Question

Quizplus · Accepted Answer

The increasing prevalence of obesity is a major problem for the set-point theory because if body weight was truly regulated by a fixed set point, obesity rates should remain relatively stable. The fact that obesity rates have been steadily increasing suggests that factors other than a set point are involved in body weight regulation. The other answer choices are not directly problematic for the set-point theory.
