It turns out there’s a scientific reason behind all those warnings from our moms about not drinking on an empty stomach.
Content creator Loryn Powell took to her Facebook page to share her experiment, testing whether drinking on a full stomach compared to an empty one really impacts your blood alcohol content (BAC).
First, she ate an entire pizza before taking “four shots of vodka and breathalyz[ing] every 30 minutes.”
For the second part, she planned to not eat “anything all day” and follow the same steps the next day, taking four vodka shots and using a breathalyzer at regular intervals.

After eating a thick-crust pizza and downing four shots like she was on spring break, Powell’s BAC measured 0.046 percent after the first 30 minutes.
“That’s very high,” she commented. An hour later, her breathalyzer showed 0.044 percent—perhaps the pizza dough was working its magic by soaking up some of the alcohol.
By the fourth hour, Powell’s BAC had returned to zero.
“You’d think four shots of vodka would get me to a 0.08 percent,” she remarked.
The second test, on an empty stomach, took a much different turn.
After taking four shots on an empty stomach, her BAC also hit 0.046 percent in the first 30 minutes—identical to the result after eating pizza.

“The pizza saved me from getting a 0.08 percent,” Powell said, even calling pizza “a superhero.”
She realized, “Okay, the first 30 minutes don’t matter if you have food in your stomach or not. It’s what happens AFTER. Woo!”
Two hours in, her BAC remained high at 0.088 percent. By three hours, it was 0.075 percent.
At four hours, she was at 0.056 percent, and by hour five, it was still 0.044 percent.
It took a full eight hours for her BAC to finally return to zero when drinking on an empty stomach, which was twice as long as it took when she drank on a full stomach.
