BAD IDEA
Can I survive on beer alone?
No, beer lacks the nutrients your body needs to survive—unless you’re a yeast.
Surviving on beer alone is a terrible plan. Sure, it provides calories, but it lacks essential proteins, fats, vitamins, and minerals your body desperately needs. Drinking only beer leads to malnutrition, organ damage, and eventually death. So unless you want to end up as a cautionary tale, keep the beer as a treat, not a food group.
Relying solely on alcohol is dangerous and can cause serious health problems. Seek medical advice if you or someone you know is doing this.
