Ross and Hugo Turner, 36-year-old twins from Christow, Devon (UK), both take daily vitamins and follow similar eating habits and exercise routines.

Over the course of 6 months, Hugo supplemented his diet with plant-based liquid vitamins, such as seaweed, and used vegan Omega-3 oil derived from plants found in the ocean, instead of using fish-based products.

Meanwhile, Ross took an animal-derived vitamin pill each day.

At the end of the study, blood test results showed that Hugo, who followed a plant-based supplementation plan, had much higher levels of essential nutrients in his blood compared to his brother Ross, who used animal-derived vitamins.

Throughout the experiment, both brothers were regularly tested for levels of fatty acids, vitamins, and minerals in their blood.

Ross shared on social media, “At the halfway point, our blood tests showed a small difference. But the final results really showed the most significant changes.”

By the end of 6 months, the blood tests showed the positive effects of using plant-based supplements. Hugo’s Omega-3 levels improved, and his Vitamin D3 levels also rose significantly.

Omega-3, found in fatty fish and walnuts, is believed to support brain and heart health, while Vitamin D is important for maintaining healthy bones and teeth.

Some research suggests that a plant-based diet, rich in vegetables, whole grains, and nuts, can lower the risk of heart disease, reduce biological age, and even assist with weight loss.

However, other studies suggest that long-term plant-based diets may lead to nutrient deficiencies and may not be appropriate for all ages.

Other Comparisons

In 2023, the twins also tested whether longer workout sessions would bring more benefits than shorter ones.

For 12 weeks, Hugo trained for 20 minutes, while Ross worked out for twice as long, 40 minutes.

The results showed that their physical fitness, strength, and endurance improved nearly equally.

Earlier this year, Hugo followed a high-fat, low-carbohydrate diet, primarily consuming calories from olive oil, butter, nuts, eggs, and avocados.

Meanwhile, Ross started eating more carbohydrate-rich foods like pasta and rice, while reducing his intake of high-fat foods.

Both continued to eat clean protein sources like chicken and protein shakes.

At the end of 12 weeks, Ross gained 2.2 pounds of muscle and lost 2 pounds of fat, while also lowering his cholesterol and reducing his visceral fat (the harmful fat linked to chronic diseases) from 11.5% to 11.1%.

However, Hugo appeared worse after following the high-fat diet. He gained 6.6 pounds, lost 0.6 pounds of fat, saw no change in his cholesterol, and increased his visceral fat from 11.4% to 12.6%.

The two brothers are now planning to try intermittent fasting and non-fasting diets for 12 weeks to see how this popular weight loss method affects their bodies.
