We have two kinds of vegetarian/vegan at work. The scrawny, dizzy, can barely stand up kind with no muscle tone and huge black bags under their eyes who eat a pile of leaves for lunch and the morbidly obese, chips-and-soda vegans who look like zombies, too, but are very fat. They are both in terrible shape, but one gets excess calories and the other does not. Both look like they need to be admitted and force-fed real chicken soup for a month.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
