Question

Quizplus · Accepted Answer

Damage to the ventromedial hypothalamus can result in rapid stomach emptying and high insulin levels, which can cause an individual to feel hungry even if they have recently eaten. This can lead to overeating and weight gain.

Answer: B 
 High CCK levels can help regulate appetite by signaling a feeling of fullness. However, animals with ventromedial hypothalamic damage may be under-responsive to these signals and continue to eat despite feeling full. Additionally, under-responsiveness to tastes may also contribute to overeating.
