Park Seo-Yeon, 33, who goes by the online handle "the Diva," said she starts her hours-long online meal each night at 8 p.m. and thousands of people log in to watch her devour her food, CNN reported Thursday.
Park said she makes about $9,300 each month from generous fans who donate to keep her channel running.
Park said her fans give various reasons for wanting to watch her eat.
"A lot of my viewers are on diets and they say they live vicariously through me, or they are hospital patients who only have access to hospital food so they also watch my broadcasts to see me eat," she said.
Park said about 60 percent of her viewers are female.
"One of the best comments I ever received from a viewer who said that she had gotten over her anorexia by watching me eat," Park said. "That really meant a lot to me."
Officials with Afreeca TV, which hosts Park's evening meal video stream, said her channel is one of many "eating rooms" available on the site.
"We think it's because of three big reasons -- the rise of one-person households in Korea, their ensuing loneliness and finally the huge trend of 'well-being culture' and excessive dieting in Korean society right now," Afreeca TV spokeswoman Serim An said.
