Can you live without the Hypothalamus?
people do live with problems that have affect their hypothalamus, but i am not sure if it is possible to be born without one or have it be removed successfully
No; normal, healthy individuals without a disease affecting their hypothalamus do not need to "reset" their hypothalamus with medications.

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.
