For competitive eater Nela, there was only ever one way she could mark reaching a milestone such as 10,000 subscribers to her YouTube channel: by eating. To celebrate her recent achievement, she tucked into a rainbow-colored cake complete with a staggering 10,000 calories. As if that wasn’t enough of a challenge, she munched her way through the entire sweet feast in an impressive time of under 15 minutes! Credit: YouTube/Nela Zisser
