For decades, the fitness community has been torn: is it high fat or high fuel?
A recent experiment put the debate in old age using a pair of identical twins that share 99% of the same DNA. The results can surprise you.
At the end of the 12-week experiment, both Ross and Hugo Turner, 36-year-old professional adventurers from the UK, were more capable and weaker-but a brother had significantly more energy than the other.

For the experiment, the Gemini ate three meals and two snacks a day from a food delivery service, frive, plus 350 calorie protein tremors. Their daily intake reached about 3,500 calories, according to Business Insider.
Hugo went on low fuel, adding high -fat foods such as olive oil, butter, nuts, eggs and avocados in its FRIVE meal plan. Meanwhile, Ross stuck in a more “balanced” plan, loading with carbs like pasta and rice and avoiding fats.
Turners also attended similar drills – cardio training and strength with fitness equipment at home – and rested every three days. Their progress was monitored by sports scientists at the University of Loughborough.
After 12 weeks in the high fuel diet, Ross won 2.2 pounds of muscle, lost 2 pounds of fat, improved its cholesterol level and lowered its inner visceral fat from 11.5% to 11.1%.
Hugo gained 6.6 pounds, lost only 0.6 pounds of fat, with no change in his cholesterol and increased his visceral fat from 11.4% to 12.6% after following the high fat diet.
Visceral fat is the dangerous fat preserved around the internal organs, associated with chronic diseases such as heart disease and type 2 diabetes.
The brothers, both strong and capable before the experiment, also tested their physical ability after 12 weeks. While the two saw almost identical results in force tests, Hugo fought with cardiovascular gym and consistency after the high fat diet.
“I never felt good,” Hugo Business Insider told. “I was eating at least six times a day and never felt full or satisfied, so I was constantly hungry. But equally, I haven’t had clashes that I would probably accompany them with a fuel diet the highest. “
Ross, on the other hand, said he felt complete, but lost the structure and satisfaction of high fat foods. He agreed to come out occasionally on a small piece of dark chocolate to curb his wishes.
Steven Harris, a performance physiologist at Loughborough University who worked with Turners, told Business Insider that it was significant that both twins saw improvements in the cardiovascular gym and metabolic health. However, he noted that the high fuel diet seemed to help Ross push himself a little more difficult, potentially during 12 weeks of training, not just in the final tests.
This is not the first time the Turner brothers have dealt with such a challenge. The duo has completed several three-month fitness programs, including experiments on whether longer drills are more effective than short explosions of exercise and whether a vegan or comprehensive diet affects the mass of muscle and chronic disease biocarkers.
The diet’s restrictive plans are more popular than ever, with regimes such as these, Super Carb, and Whole30 that promises rapid weight loss and other benefits, significantly limiting certain food groups.
While it is true that many of these “fictional” diets can help you pour a few pounds, research suggests that they may not be the best long -term choice for weight management. Some studies also show that they can adversely affect your overall health.
In 2023, researchers from the Nagoya University Graduate School in Japan found that extreme diets that drastically reduce or carbohydrates or fat intake are associated with the highest cause and cancer -related mortality.
After all, experts agree: there is no access to an appropriate size when it comes to food. On the contrary, focus on creating a well -balanced diet that supports all body functions, from the immune system and cognitive function to heart health and mental well -being.
