A set of identical twins decided to put vegan and meat-based diets to the test to see which was best.
Hugo and Ross Turner took part in a study which involved one going plant-based while the other consumed an omnivore diet.
The duo took part in the study with Kings College London for a 12-week long study and ate the same amount of calories each day.
They even carried out the same gym training when Hugo ditched meat and dairy while Ross enjoyed those foods with fish.
At first Hugo said the switch to a plant-based diet wasn’t easy, but he eventually found himself more energetic.
Speaking to the BBC, he said: “I was on the vegan diet and it really does take a hit on your body.”
He added: “I think the first couple of weeks it was really craving and wanting meat and dairy and cheese. I love cheese.
“I was now having to eat fruit and nuts and alternatives that didn’t have any dairy in them.
“I was eating a lot more wholesome food, which meant that my sugar levels were a lot satiated during the day. I felt more energetic.”
Meanwhile his meat-eating twin said his gym performance was “up and down a little bit more”.
Ross noticed how much processed food he was eating after checking out his twin’s super healthy vegan meals.
By the end of the 12-week study, the men found there “wasn’t a huge difference, if any” between the two diets.
But Hugo did see his cholesterol levels drop “off the scale”, while also losing weight and boosting his resistance to type-2 diabetes.
At the start of the diet, Hugo weighed 13.2st and had 13% body fat.
