Identical twins Hugo and Ross Turner, known for their jaw-dropping experiments to explore how genetics and environment shape the human body, are back with their next audacious challenge: a 30-day diet swap that will see one twin eat only ultra-processed foods while the other sticks to a clean, whole-food regimen. The twist? They’re doing it to uncover the truth about how modern diets impact our health—and whether we’re really what we eat.
The British adventurers, who’ve previously tested everything from altitude training to alcohol consumption, are no strangers to pushing their bodies to the limit. But this experiment, conducted in partnership with leading nutrition scientists, might be their most revealing yet. “We’ve always been fascinated by how small changes can have huge effects,” says Hugo. “This time, we’re tackling one of the biggest debates in health: processed food.”
For 30 days, Ross will consume a diet packed with ready meals, sugary snacks, and fast food—staples of the modern Western diet. Meanwhile, Hugo will eat only fresh, unprocessed foods like vegetables, lean proteins, and whole grains. Both twins will undergo rigorous testing before, during, and after the experiment, tracking everything from gut health and brain function to energy levels and mood.
“We’re not just looking at weight gain or cholesterol,” explains Dr. Sarah Berry, a nutrition scientist involved in the study. “We’re examining how these diets affect everything from sleep quality to mental clarity. The results could change how we think about food.”
The twins, who share 100% of their DNA, are the perfect subjects for such a study. “Any differences we see will almost certainly be due to diet, not genetics,” says Ross. “It’s a unique opportunity to isolate the impact of processed foods.”
But the experiment isn’t without its challenges. Hugo admits he’s dreading the monotony of his “clean” diet, while Ross is bracing for the inevitable sugar crashes and bloating. “I’m not looking forward to feeling like rubbish,” Ross laughs. “But if it helps people understand the risks of processed food, it’s worth it.”
As the twins gear up for their latest adventure, one thing is clear: their willingness to put their bodies on the line for science is as inspiring as it is extreme. “We’re not saying everyone should eat like Hugo,” says Ross. “But we hope this experiment will make people think twice about what’s on their plate.”
Stay tuned—because when the Turner twins are involved, the results are never boring.
