The 36-year-old reality star took to Twitter on Tuesday, joking that she recently lost a few pounds as a result of the virus.
“The flu can be an amazing diet,” Kardashian West wrote. “So happy it came in time for the Met lol #6lbsdown.”
The tweet left some social media users scratching their heads, with one writing, “THIS IS NOT A THING.”
Another Twitter user wrote: “Girl I love you and all but what.”
Kardashian West doesn’t always rely on such peculiar diets, though. The mother of two revealed to PEOPLE in October that she had lost nearly 70 pounds after welcoming her son Saint almost a year earlier.
“I think dieting is so important to weight loss, whereas, I didn’t really ever think that before,” she said then. “I thought, ‘Oh, I can work out, I can just eat whatever I want.’ But you have to work out all the time.”

The star worked hard to reach her weight goal, 120, and hasn’t been shy about showing off her body.
