King Henry the 8th had an all meat diet. As such he had scurvy. He was called the Scurvy Nave. He had open sores on his legs where pus would leak out. My hope for the guy who is on a grass fed beef diet is that he will be able to thrive with his situation.
Your post tells me you would benefit from a multivitamin. That give you Vitamin C as well as other other supplements the “Lion Diet” would miss.
