The Gut Microbiome
The vegan diet also induced interesting changes in Hugo’s gut microbiome, the population of beneficial bacteria within the human digestive system. According to fecal sample analysis performed by Atlas Biomed, Hugo’s microbiome changed in ways that potentially increased his resistance to chronic illnesses such as obesity and type 2 diabetes. Surprisingly, both twins observed a decrease in microbial diversity in their gut, a factor usually associated with reduced resilience against certain chronic illnesses like Crohn’s disease.

The twins acknowledged that a 12-week period is relatively short for a typical dietary study. They expressed that, given a chance to repeat the experiment, they would prefer to conduct the trial over six months to a year for more accurate and comprehensive data. Despite the short duration, the experiment was enlightening, and the brothers expressed their intention to incorporate more plant-based foods into their diet moving forward.
In conclusion, they believe the optimal diet is a blend of plant- and animal-based foods. The experiment underscored that both diets have benefits, and neither one was superior overall. Hugo and Ross suggest starting small by replacing snacks with vegan alternatives for those considering a vegan diet. They aim to encourage individuals, specially dedicated meat-eaters, to broaden their dietary horizons and consider plant-based substitutes.
The Turner twins’ unique dietary journey adds to their repertoire of fascinating experiments. From scaling Mt. Elbrus in Europe in 2015 to replicating Sir Ernest Shackleton’s 1914 expedition in Greenland using vintage gear, the Turner twins continue to inspire and educate the world about the potential of the human body, mind, and spirit.
Contemplating the Switch to a Vegan Diet?
To reap the benefits of plant-based foods, you do not necessarily need to transition completely to a vegan or vegetarian lifestyle. For many individuals, simply incorporating more plant-based foods and reducing the intake of processed foods in their everyday diet can bring substantial improvements in health and reduce the risk of heart disease.

A diet rich in vegetables and fruits, regardless of meat or dairy consumption, is linked to a decreased likelihood of heart disease and premature mortality.
Globally, various dietary patterns that incorporate different amounts of meat and dairy help with longevity and more robust health. Examples from the ‘Blue Zones’ include the traditional Mediterranean diet, the vegetarian diet of the Seventh-Day Adventists, and the largely plant-based diet of Okinawans in Japan. A common characteristic among these diets is their primary reliance on plant-based foods.
