United Kingdom, July 30 -- Hilaria Baldwin "started dieting" at the age of five.

The 42-year-old star has opened up about her struggles with various eating disorders, revealing that she became "afraid of how many calories might be in toothpaste" at the peak of her problems.

Speaking to Page Six Radio, Hilaria explained: "I did all of it. I did anorexia, I did bulimia, I did overeating, I did undereating."

On reflection, Hilaria now believes looked "fine" at the height of her troubles - but she saw things differently in that moment.

She explained: "I look back and I looked fine. But I thought I was a whale [back then]. I just thought there was something broken inside of me."
