The lateral hypothalamus (LH) is primarily involved in regulating hunger and energy balance; it stimulates appetite and promotes feeding behavior. In contrast, the ventromedial hypothalamus (VMH) plays a critical role in satiety and suppressing appetite. Together, these areas help maintain energy homeostasis in the body by balancing hunger and fullness signals. Dysfunction in either region can lead to issues such as obesity or anorexia.
Stimulating specific areas of the hypothalamus can have various effects on the body and behavior. For example, stimulating the lateral hypothalamus can increase hunger and lead to increased food intake, while stimulating the ventromedial hypothalamus can suppress appetite and cause decreased food intake. Stimulating other areas of the hypothalamus can also regulate sleep, thirst, body temperature, and hormone release.

Damage to the ventromedial hypothalamus can lead to overeating, obesity, and impaired satiety signals. This region is involved in regulating feelings of fullness and controlling food intake, so its destruction can disrupt feeding behavior and satiety regulation.
it is the brain stem
Destruction of the lateral hypothalamus can lead to loss of appetite, decreased food intake, and potential weight loss due to disruptions in hunger and satiety signals. It can also impact motivation and drive to engage in behaviors related to food seeking and consumption.
Ventromedial hypothalamus and the lateral hypothalamus.
Ventromedial hypothalamus
Stimulating specific areas of the hypothalamus can have various effects on the body and behavior. For example, stimulating the lateral hypothalamus can increase hunger and lead to increased food intake, while stimulating the ventromedial hypothalamus can suppress appetite and cause decreased food intake. Stimulating other areas of the hypothalamus can also regulate sleep, thirst, body temperature, and hormone release.
in short, yes, your lateral hypothalamus controlls your feeling of hunger, which without feeling this drive you wouldn't be compelled to eat. if your ventromedial hypothalamus were to suffer damage it would have the opposite affect, you would never feel full. as far as i know this has only been tested on mice using lesions in the brain.

Ventromedial Hypothalamus is removed

lateral hypothalamus
The lateral hypothalamus is known to be involved in regulating hunger and feeding behavior. It is also implicated in reward processing and motivation, as well as in the sleep-wake cycle and arousal. Damage to the lateral hypothalamus can lead to decreased food intake and ultimately weight loss.
Destruction of the lateral hypothalamus can lead to loss of appetite, decreased food intake, and potential weight loss due to disruptions in hunger and satiety signals. It can also impact motivation and drive to engage in behaviors related to food seeking and consumption.
The hypothalamus is a small mass below the thalamus and forms floor and part of the lateral walls of the third ventricle.
