The British actor, 52, attributed her thinness to a “physical manifestation of grief” following the deaths of her mother and stepfather.
Her mother, Judy Loe, died in July 2025 from cancer, and her stepfather, Roy Battersby, passed away in January 2024.
Beckinsale explained that watching her loved ones suffer and die caused her body to “close down” due to shock and trauma, leading to a loss of appetite.
She criticized those making "nasty" comments, stating she refuses to become like them and appreciates the upbringing her parents provided.
