The ventromedial hypothalamus is most likely to be the affected brain region in Phyllis's case. This area of the brain is responsible for regulating hunger and satiety signals. Damage or dysfunction in the ventromedial hypothalamus can lead to insatiable hunger, even after consuming large meals, which can result in weight gain.
