An Experiment on Identical Twins – What Happens When One Eats Meat and the Other One Is Vegan?

how to be a vegan

Experiments involving genetically identical twins have fascinated the world of science for many years, as they can provide a real indication of the impact of environmental conditions on the human body. The pair of identical twins Ross and Hugo from the UK, decided to experiment on themselves and see what the impact of vegan diet gives on the human body and how it is different than an omnivore diet.

For 12 weeks Hugo kept on a vegan diet while Ross could eat whatever he wanted emphasizing a meat-rich menu. Scientists from King’s college monitored their weight, cholesterol, sugar-level, fat percentages, and other medical data. The Turner twins thought that because they were genetically identical, comparing their diet menus could give more insight into the impact of nutrition on the human body.

The twins did not just settle for the nutrition menus they were taking care of: the two practiced vigorously five to six times a week. The results surprised both the scientists and the twins.

Results of the Experiment

Ross, who was on a meat diet, began the experiment weighing 79.3 kg and having 13 percent fat. During the experiment he raised his fat percentage to 15%, and the muscle mass by 2 kg. He finished the experiment weighing 86 kg.

His brother Hugo, who was on a vegan diet, had a significant improvement in medical parameters: The cholesterol and sugar in his blood dropped. He reported a high sense of energy. Hugo started the experiment weighing 84 kg with 13% fat, and finished the experiment weighing two kg less, with fat percent dropping to 12%. But there were also some negative results: for reasons he didn’t know, he lost his libido – sexual desire.

The scientists also collected fecal samples before and after the experiment and found that Hugo’s intestinal bacterial population was more resistant and reduced the risk of developing obesity and type 2 diabetes. Ross’s intestinal bacterial population did not change at all from the beginning of the experiment. The twins said that they will consider repeating the experiment in the future, for a longer period of six months. For now, they plan to involve more plant-based products and whole-grain foods on their diet.
