A Nutritionist Watched Miranda Kerr Describe Her Diet and Said the 43-Year-Old Model Is “Probably Tired All The Time” and “Probably In A S–Tty Mood.”

Miranda Kerr’s diet skips bread, dairy, wheat, eggs, and seed oils, and experts say cutting that much can leave real gaps in protein, fiber, calcium, iron, and energy. One dietitian says she wouldn’t put a woman in her 40s on it.

Kerr, 43, laid out her eating habits on Kristin Cavallari’s “Let’s Be Honest” podcast, and dietitians who watched had concerns.

“Miranda genuinely seems to care about eating for her health, but her diet is very restrictive,” said Sophia Deahl, who told The Post it’s not one she’d recommend for the average client Kerr’s age. Cutting bread, dairy, wheat, eggs, and seed oils, she says, risks leaving out protein, fiber, calcium, iron, B vitamins, and omega-3s.

The restrictive style isn’t random biohacking. Kerr spent years following Medical Medium protocols, the controversial Anthony William system built on heavy elimination of eggs (his claim: viruses “feed” on them), dairy, and gluten, plus daily celery juice. She’s appeared alongside William, credited him publicly with changing her health, and folded his rules into her KORA Organics content. In a May interview she said she’d moved on to a microbiome-focused plan with gastroenterologist Dr. Sabine Hazan, but that one is still dairy-free, gluten-free, and egg-free.

The bigger worry is what all that restriction does over time. Deahl says the more foods that become off-limits, the harder it gets to eat flexibly at restaurants, while traveling, or when you just want something different, and that can slide into anxiety around food.

Dr. Idrees Mughal, a lifestyle medicine doctor, called the plan “disordered” on TikTok, while noting he couldn’t diagnose off a video clip. “A healthy diet is not defined by how many foods you eliminate, how exotic your meat is or whatever wellness trend you happen to be doing,” he said.

Deahl does credit a few “positive foundations”: whole foods, a variety of protein, and eating before coffee, which can help energy and blood sugar. Her advice is to borrow the principles, not copy the prescription. “Assuming you need to eliminate the same foods as a 43-year-old celebrity because it works for her? That’s where I’d be much more cautious.”
