Answer: Damage to VENTROMEDIAL nucleus of the hypothalamus might account for his weight gain.
Explanation:
VENTROMEDIAL nucleus is part of the hypothalamus that is responsible for inducing the feeling of fullness after eating. It tells us when we have eaten enough and to stop eating.
When the ventromedial hypothalamus is damaged, digestive reflexes become overactive and empty the gut abnormally fast. Therefore, the animals start eating sooner than normal and therefore overeat. The rush of extra food cannot be metabolized so it is stored as fat.
Will was involved in an automobile accident that caused damage to the VENTROMEDIAL nucleus of his hypothalamus which led to theweight gain.
