Looks like the Hodge twins once again have changed their diet. They went from eating meat, to eating vegetarian, to calling themselves 'vegans' even though they were still technically vegetarian. Anyway, now they call themselves "flexatarian."
In the video they say they will be on a mostly plant-based diet, but will consume meat about 3 times a week.
The reason why they stopped the vegan/vegetarian thing was because they said they noticed a decrease in muscle mass. Well, much respect for them trying!
