“After eight weeks of testing opposite diets, identical twins show drastic health differences, with veganism taking the lead

In a bold food experiment, identical twins were pitted against each other in a battle of diets to see how drastically their health could change after eight weeks of eating entirely different meals. The twins took part in the Netflix show You Are What You Eat, where one twin went vegan while the other stuck to a traditional omnivore diet, consuming meat and animal products.

The results were surprising, to say the least. Almost all the twins who took part in the experiment reported significant lifestyle changes after experiencing the effects of the two diets. In particular, the twin who followed the vegan diet showed notably improved health markers, including a lower risk of heart disease, a higher life expectancy, and even a stronger sex drive.

Among the most striking transformations were the cheesemaking brothers Charlie and Michael. Before the show, Charlie had been a staunch omnivore, but after trying the vegan lifestyle, he found the benefits so compelling that he decided to become nearly vegetarian. Although he still enjoys a small amount of meat, especially in Chinese dishes, he’s about 90% on the road to eliminating meat from his diet entirely. Michael, who had already been a pescatarian before the show, embraced full vegetarianism after the experiment.

Other twins also made noteworthy changes. Sisters Pam and Wendy stuck to an omnivore diet but reduced their meat consumption by roughly half. Brothers John and Jevon were so impacted by the experiment that they decided to quit red meat altogether, while sisters Carolyn and Rosalyn continued to eat animal products but began phasing out some meats from their meals.

Even outside of this experiment, similar trials have shown twins testing meat versus vegan diets. Twins Hugo and Ross participated in a 12-week version of the challenge, with Hugo trying the vegan route. Initially, Hugo struggled with cravings for meat and cheese but reported feeling much more energetic and healthier as he adjusted to his new diet.

The experiment’s findings reflect a growing body of research supporting the health benefits of plant-based eating, particularly for heart health and overall vitality. It seems that after just a few weeks, the vegan diet offers significant improvements, while the meat-heavy diet could contribute to long-term health risks.

As more people shift toward plant-based diets, the question remains: Could this twin experiment serve as a turning point for others considering the transition to veganism? For these twins, the results speak for themselves—healthier, more energetic, and perhaps most surprisingly, more willing to embrace veganism in the long run.
