Question

Quizplus · Accepted Answer

The set point theory suggests that the body has a certain predetermined "set point" of adipose tissue, and when this set point is exceeded, a signal is sent that causes food intake to decrease and/or energy expenditure to increase in order to return to the set point. This theory explains why weight loss can be difficult, as the body may resist going below its set point. Option A is incorrect as it suggests an increase in food intake triggers a decrease in food intake, which is contradictory. Option B is incorrect as it suggests insulin, rather than adipose tissue, is the determining factor in weight regulation. Option D is incorrect as it suggests a decrease in serotonin production causing decreased appetite, which is contradictory.
