Anyone who's had Guinness will tell you there's nothing else they'd drink except that. It tastes pretty full, heavy sometimes, and it's no surprise people think that this stuff is just jam packed with calories. Scientists decide to provide the facts you didn't know about the libation.

12 ounces of Guinness Draught contains 126 calories.

Drinking freshly-squeezed orange juice is 168 calories.

The reason it's less: Guinness is not very alcoholic.

It looks thick and creamy because it contains nitrogen.

Which doesn't contribute to the calorie count. So don't worry. It's not that high in calories!
