On Monday, Molly Schuyler ate two 72-ounce steak meals at The Big Texan Steak Ranch.

In less than 15 minutes.

After breakfast.

"We witnessed history," Big Texan co-owner Danny Lee said. "If there's a zombie apocalypse, I want to stay away from this girl."

Schuyler, a competitive eater from Bellevue, Neb., finished her first medium-rare steak in less than 5 minutes to set the record for fastest time to eat the dinner.

She rushed to finish the first steak and the sides, including a baked potato, shrimp, a salad and a bread roll, she said.

"The second one, I wasn't going really for time," she said. "There was no point. I had to do it in under an hour, so I was fine."

The self-described "bottomless pit" is no stranger to gastric glory. In January, she devoured a record 363 wings in 30 minutes at a competition in Philadelphia, earning a $22,000 prize, according to philly.com. She was listed as being 5-foot-7 and weighing 125 pounds at that contest. She probably weighed about 10 pounds heavier after eating both steak dinners Monday.

Lee said Schuyler's slight frame belies her eating ability and makes her accomplishment that much more remarkable.

"Molly had called about a year ago, she said, and we took it as a hoax," Lee said. "This little girl walked in here and … she's one of the daintiest, smallest ladies that I've see try the 72-ounce steak."

But she's not finished yet. Schuyler said she plans to return to the Big Texan with the goal of eating three of the steak dinners in one sitting.

Schuyler offered advice to anyone who would want to try the challenge.

"Just be careful when you eat steak," she said. "It's a very chokeable food."
