Ho much can I drink beer?

I'm going to a party next Saturday and I've decided I'm gonna have one beer. I normally dont drink any type of alcohol because i dont really like it (except white whine here and there with my family) but I've never tried beer before so im gonna give it a try. I only want one though and i just wanna know if one beer will get me any where near tipsy because i dont want to be drunk. I'm a female, age 17, 5'2 and weigh roughly about 150. I heard if you eat more before you drink the less likely you will become drunk so ill eat a good amount beforehand. idk if someone can tell but if so thanks a lot.
