Nutrient requirements don't increase nearly as much as caloric requirements under high activity. Additionally, vegan diets with enough nutrients tend to be calorie heavy.
So flipping that around, my point is that it's difficult to have a healthy vegan diet that gives you enough nutrients, without an extremely high activity level.
