Geldof spoke to The Sun back in 2011 at the premiere of the film One Day with her husband Thomas Cohen and addressed the growing speculation at the time that she was anorexic.
But the TV presenter explained that her doctors told her to clean up her diet and focus on living a healthier lifestyle.
"I had cholesterol and the doctors said stop eating s--t. So I did. If you stop eating pizza and chips you then don't look like you used to," she said.
"Do I really look that thin? Let's be honest. How did I do it? I just stopped eating McDonald's and f--king s--t every day."
Peaches added, "I used to eat s--t every single day. I used to wake up with my boyfriend and eat crap. I had the heart of a 90-year-old gangster….People are like, 'Peaches is scary and anorexic.' Not really. It's ridiculous."
And less than a week after her sudden passing, Peaches' Instagram account seems to have been removed. In addition, her Twitter page has been made private.
The mother of two was an active user on the site and shared lots of photographs of her adorable two sons, Astala and Phaedra.
The last picture that she uploaded was on Sunday, just hours before she was found dead, and showed her late mother Paula Yates holding her as a little toddler.
Her father Bob Geldof said in a statement that the family was "beyond pain."
Peaches "was the wildest, funniest, cleverest, wittiest and the most bonkers of all of us," he added. "Writing 'was' destroys me afresh. What a beautiful child."
