The Diet That Changed Miley Cyrus' (33) Life

Miley Cyrus has gone through more public dietary transformations than almost any other pop star, each one tied to a real health discovery rather than a passing trend. What changed her life most, though, was not adopting a diet, it was the moment she finally had to walk away from one.

Her journey stretched across more than a decade, from a defensive teenage tweet about gluten to an emotional admission on a major podcast years later. Both moments reshaped how she actually eats today.

None of it followed a straight line. Here is the real story behind the diet that changed Miley Cyrus’s life.

It Started With A Tweet About Gluten

In 2012, Cyrus publicly clarified that she was not battling an eating disorder, but rather managing a gluten and lactose allergy, tweeting bluntly that gluten is crap anyway, according to Fox News. She encouraged fans to try cutting gluten for just a week to notice the difference themselves.

That early shift toward gluten and dairy free eating stuck, and became the foundation for an even stricter diet a year later. By 2013, she had moved into full veganism, a lifestyle she would follow with real intensity for the next several years.

Seven Years Of Strict Veganism Took A Toll

Cyrus described her vegan years, which ran from 2013 to 2019, as the strictest version of the diet imaginable. Performing at Glastonbury during that stretch, she has said she felt like she was running on empty, according to Yahoo, despite loving the actual performance itself.

She has since said she believed she was malnourished during parts of that period, describing her brain as noticeably less sharp than it is now. Joint pain and persistent brain fog eventually became impossible to ignore, pushing her toward a real reconsideration of the diet entirely, according to Sportskeeda.

Ending It Meant Grieving, Literally

Her first meal back on animal products came from her then husband, Liam Hemsworth, who cooked her fish on the grill. “I cried, like, for a long time. I cried for the fish,” she admitted, describing just how emotionally difficult the shift actually was for her.

The backlash followed almost immediately, with fans upset and some nutritionists publicly questioning her reasoning as vague, according to The Things. Cyrus has maintained the decision came down entirely to her own health, not a rejection of the values that led her to veganism in the first place.

Miley Cyrus’s diet today looks like neither extreme she has lived through, mostly plant based with fish and gluten reintroduced specifically where her body seemed to need them. The real change in her life was never a single food group, it was learning to let her own health outrank the fear of disappointing anyone watching.
