Claire Foy reveals years of undiagnosed parasites and her radical diet shift

Actress Claire Foy has revealed she lived with parasites for years without realizing it. The discovery came after she struggled with unexplained weight loss. Doctors later confirmed the issue, which she believes began during a trip to Morocco.

Foy first noticed something was wrong when she kept losing weight for no clear reason. Tests eventually showed she had been hosting parasites, possibly for five years or more. Instead of using antibiotics, she decided to tackle the problem through diet alone.

Her new routine involves cutting out gluten and sugar due to an autoimmune condition. She also removed caffeine entirely, despite previously drinking up to 15 cups of tea a day. While she follows strict eating habits at home, she occasionally makes exceptions when dining out.

The actress has not shared exact details of her dietary plan or how long it took to adjust. However, she has made it clear that caffeine will no longer be part of her life.

Foy's health changes came after years of unknowingly living with parasites. Her approach relied on diet rather than medication. The adjustments now form part of her daily routine, though she remains flexible when eating out.
