Water and calories are needed to keep a human going. There's no need for the water to come out of beer and there's no need for the calories to come out of candy. Moderation still applies even though water and calories are necessary to life. Dehydration will kill you, Hyperhydrosis will kill you. Starvation will kill you. Overeating will take you to Lord Beetus' torture chamber. And kill you. And contribute to killing the environment. And kill people who are stuck behind you in an emergency. And kill the backs of all the poor health workers who'll have to lift your Fat. Dead. Ass.
