Sonya Thomas broke her own hot dog-eating record in New York on Wednesday, after eating 45 hot dogs and buns in 10 minutes.
In last year's championships, Thomas was the clear winner in the women's competition after devouring 40 hot dogs.
Revealing the method behind her success, 'The Black Widow' told CNN: "My technique is I dunk two hot dogs in the water cup and then eat."
Meanwhile, the men's heat saw Joey 'Jaws' Chestnut win another title, tying his 2009 world record by downing 68 hot dogs in 10 minutes.
Chestnut said of his future ambition: "My record is 68 hot dogs in 10 minutes, and I'm going to break it hopefully just by eating it like a beast."
Thomas and Chestnut weighed in at 100 and 210 pounds respectively.
