An average human that does moderate activity burns 2500 calories per day which is 912,500 calories per year.

22 gallons of beer at 130 calories per serving is 30,507 calories... That just isn't enough...

One keg serves 124 sixteen ounce servings each serving is 173.3 calories. So we need 5265.5 pints rounded up which is 42.5 kegs rounding up.

Okay people so we need to drink 14 beers per day to stay alive.

Although... that means we would only get like 1.36 MPG
