“Yeah, the gross stuff,” she said of testing for the “issues” she had going on with her stomach.

“I kept losing weight and I didn’t know what was going on. I was just like, ‘I’m eating everything.’ I was so hungry,” she added of her symptoms.

Claire thinks she got the parasite in Morocco, and that she had it for “at least five years.”

“They travel as a pair. I got told by the doctor, gross, absolutely rank. It’s disgusting,” she continued.

“So that’s why I gave up caffeine. I basically had to go on this diet…I didn’t want to take really hardcore antibiotics and stuff like that, I took all this little gross stuff, and part of that was giving up caffeine. Once you’ve given it up, it’s such a mission to give it up.”

Claire said she used to have “at least 15 cups of tea a day” and typically two coffees.

She also said she has an unnamed autoimmune condition.

“This is my big secret, I feel like I’m in The Traitors or something, and I’m letting everyone know that I’m related to someone. I don’t actually eat gluten or sugar except when I go out for dinner,” she said, apart from exceptions during certain special events.

“It doesn’t have an impact on me,” she went on to explain. “It’s just because I have an autoimmune condition, so I should avoid anything which causes more inflammation.”
